University of Illinois researchers have developed a way to produce 3-D images of live embryos in cattle that could help determine embryo viability before in vitro fertilization in humans.
Infertility can be devastating for those who want children. Many seek treatment, and the cost of a single IVF cycle can be $20,000, making it desirable to succeed in as few attempts as possible. Advanced knowledge regarding the health of embryos could help physicians select those that are most likely to lead to successful pregnancies.
The new method, published in the journal Nature Communications, brought together electrical and computer engineering professor Gabriel Popescu and animal sciences professor Matthew Wheeler in a collaborative project through the Beckman Institute for Advanced Science and Technology at the U. of I.
Called gradient light interference microscopy, the method solves a challenge that other methods have struggled with - imaging thick, multicellular samples.
In many forms of traditional biomedical microscopy, light is shined through very thin slices of tissue to produce an image. Other methods use chemical or physical markers that allow the operator to find the specific object they are looking for within a thick sample, but those markers can be toxic to living tissue, Popescu said.
"When looking at thick samples with other methods, your image becomes washed out due to the light bouncing off of all surfaces in the sample," said graduate student Mikhail Kandel, the co-lead author of the study. "It is like looking into a cloud."
Biobots on the front cover of Advanced Healthcare Materials: "Damage, Healing, and Remoeling in Optogenetic Skeletal Muscle Bioactuator"
Published: May 10, 2017
A deeper understanding of biological materials and the design principles that govern them, combined with the enabling technology of 3D printing, has given rise to the idea of "building with biology". With these materials and tools in hand, we are ideally poised to manufacture bio-hybrid robots, or bio-bots, that adaptively sense and respond to their environment. We have developed skeletal muscle bioactuators to power these bio-bots, and present an approach to make them dynamically responsive to changing environmental loads and robustly resilient to induced damage. Specifically, since the predominant cause of skeletal muscle loss of function is mechanical damage, we have investigated the underlying mechanisms of damage in vitro, and developed an in vivo-inspired healing strategy to counteract this damage. The protocol we have developed yields complete recovery of healthy tissue functionality within two days of damage, setting the stage for a more robust, resilient, and adaptive bioactuator technology than previously demonstrated. Understanding and exploiting the adaptive response behaviors inherent within biological systems in this manner is a crucial step forward in designing bio-hybrid machines that are broadly applicable to grand engineering challenges.

What started as a typical summer research program in Boston, MA for undergraduate engineering students, turned into the opportunity of a lifetime for Western New England University senior Kwasi Amofa from Glastonbury, CT. Amofa was recently accepted to participate in research as a prestigious Fulbright Scholar. Recipients of Fulbright awards are selected on the basis of academic and professional achievement, and their record of service and leadership potential in their respective fields.
Amofa spent the summer of 2016 doing research at the Massachusetts Institute of Technology (MIT), where one of his mentors (previously a Fulbright Scholar) encouraged Amofa to apply to the highly respected program. The application process was rigorous, however, Amofa had the support he needed from his faculty advisor and several faculty at Western New England University.
"The support that I received from my professors was tremendous. They were a great help in putting together my application and all the other requirements," Amofa explained. "My education at Western New England prepared me to dive into the research environment, and my advisors helped me discover the type of research I wanted to pursue, which is a critical first step."
Amofa will spend next year in the Netherlands working on a new project to bioengineer a cornea, the eye's outermost layer, which could potentially have a great impact on medical treatment. He will work with a group of researchers across many disciplines, including engineering, biology, chemistry, and material science, which Amofa believes will make the experience even more enriching.
"Kwasi Amofa is an exceptional student and a rigorous young researcher," remarked Hossein Cheraghi, professor and dean of the College of Engineering at Western New England University. "We are excited for this opportunity he has received, and we know he will make the most of it as he works with top researchers from various other institutions in the Netherlands next year."
The Fulbright Program, which began in 1948, is funded through an annual appropriation by the United States Congress to the U.S. Department of State, and managed by the Bureau of Educational and Cultural Affairs. Participating foreign governments and host institutions also provide support.

Microfluidics is invaluable for studying microvasculature, development of organ-on-chip models and engineering microtissues. Microfluidic design can cleverly control geometry, biochemical gradients and mechanical stimuli, such as shear and interstitial flow, to more closely mimic in vivo conditions. In vitro vascular networks are generated by two distinct approaches: via endothelial-lined patterned channels, or by self-assembled networks. Each system has its own benefits and is amenable to the study of angiogenesis, vasculogenesis and cancer metastasis. techniques are employed in order to generate rapid perfusion of these networks within a variety of tissue and organ-mimicking models, some of which have shown recent success following implantation in vivo. Combined with tuneable hydrogels, microfluidics holds great promise for drug screening as well as in the development of prevascularized tissues for regenerative medicine.
EBICS Knowledge Transfer in Action!: Demarcus Briers showcases research collaborations between BU, Gladstone Institute, and Georgia Tech to BU's Bioinformatics PhD program
Published: March 1, 2017
Mar. 1, 2017 - At BU's bi-weekly Student Seminars for their Bioinformatics PhD program, Demarcus Briers, EBICS trainee at Boston University, presented "Pattern Synthesis in Networks of Locally Interacting Stem Cell Aggregates," featuring results of research collaborations with Ashley Libby, EBICS trainee at Gladstone Institutes, and EBICS faculty Melissa Kemp of Georgia Tech and Todd McDevitt of Gladstone Institutes.
Embryonic stem cells (ESC) are generally regarded as the smallest functional units necessary to reproduce multicellular systems such as tissues and organs. However, controlled spatial patterning is likely a necessary precursor for developing organ-like tissues. Starting with 2-dimensional and 3-dimensional local interaction models of ESC dynamics, Briers and his collaborators developed a pattern classification and parameter optimization approach to maximize the occurrence of desired morphogenic patterns. Their approach uses Particle Swarm Optimization (PSO) and a pattern classification method that exploits a quantitative characterization of pattern formation. Since patterning likely imprints subsequent choices that stem cell aggregates make in lineage specification (e.g. precursors of neurons, lung cells, or muscle cells), their parameter optimization approach can be used to synthesize global patterns through local cellular interactions.

EBICS panel makes a case for how EBICS research serves society through science policy at 2017 AAAS Annual Meeting
Published: February 18, 2017
Feb. 18, 2017 - A multi-institutional panel of EBICS faculty presented on the topic of " Integrated Cellular Systems: Building Machines with Cells" at the 2017 American Association for the Advancement of Science (AAAS) Press Briefing in Boston, which brought together thousands of leading scientists, engineers, educators, policymakers, and journalists from around the world to discuss the theme of "Serving Society Through Science Policy," focusing on how to inform policies with the best available scientific evidence.
Their 90-minute session, moderated by Lizanne DeStefano (GT), consisted of three subtopics. On the topic of "Engineered Living Micro Swimmers," Taher Saif (UIUC) demonstrated a family of micro-scale swimmers, a biological machine, that emerges from interactions between muscle cells, neurons and flexible scaffolds. These engineered living machines may deliver drugs to specific locations on their own decision. On the topic of "How to Engineer a Living System," Rashid Bashir (UIUC) described, and provided examples, of several control methodologies that can be used to direct emergence. The emergence of complex connections and interactions between constituent cells is essential for their intended behavior. On the topic of "Simulation of Emergent Behavior in Multicellular Aggregates," Melissa Kemp (GT) discussed results from computational models that simulate the growth, division, and differentiation of multicellular systems into emergent patterns, and the challenges in quantifying and predicting dynamic behaviors in engineered living systems.
Altogether, these presentations address how development of increasingly complex cellular systems will be a major challenge for the next decade and beyond, as we use the knowledge gained from the sub-disciplines of tissue engineering, synthetic biology, micro-fabrication and nanotechnology, systems biology, and developmental biology. They describe the current state-of-the-art in the context of differentiating source cells from more primitive, pluripotent cells, organizing cells into populations of a single cell type to produce the components or building blocks of more higher order systems, and combining multiple cell types to produce greater functionality. Finally, the EBICS panel considers complex ethical implications as these "biological machines" increase in capabilities, exhibit emergent behavior and potentially reveal the ability for self-assembly, self-repair, and even self-replication.
Now you can build your own bio-bot! Instructions revealed by University of Illinois-Urbana Champaign
Published: February 10, 2017
Feb. 10, 2017 - In the cover article of Nature Protocols's March 2017 issue, Professor Rashid Bashir's research group shares the recipe for the current generation of bio-bots. "The protocol teaches every step of building a bio-bot, from 3D printing the skeleton to tissue engineering the skeletal muscle actuator, including manufacturers and part numbers for every single thing we use in the lab," explained Ritu Raman, now a postdoctoral fellow in the Department of Bioengineering and first author of their paper, "A modular approach to the design, fabrication, and characterization of muscle-powered biological machines."
Bashir's group has been a pioneer in designing and building bio-bots, less than a centimeter in size, made of flexible 3D printed hydrogels and living cells. In 2012, the group demonstrated bio-bots that could "walk" on their own, powered by beating heart cells from rats. However, heart cells constantly contract, denying researchers control over the bot's motion. "The 3D printing revolution has given us the tools required to 'build with biology' in this way." Raman said. "We re-designed the 3D-printed injection mold to produce skeletal muscle 'rings' that could be manually transferred to any of a wide variety of bio-bot skeletons. These rings were shown to produce passive and active tension forces similar to those generated by muscle strips. Using optogenetics techniques, we worked with collaborators at MIT to genetically engineer a light-responsive skeletal muscle cell line that could be stimulated to contract by pulses of 470-nm blue light."
"The purpose of the paper was to provide the detailed recipes and protocols so that others can easily duplicate the work and help to further permeate the idea of 'building with biology' so that other researchers and educators can have the tools and the knowledge to build these bio-hybrid systems and attempt to address challenges in health, medicine, and environment that we face as a society," stated Bashir. In addition to Bashir and Raman, Caroline Cvetkovic, a recent graduate student in bioengineering and now a post-doctoral fellow, was a co-author of the paper. Work on the bio-bots was conducted at the Micro + Nanotechnology Lab at Illinois.

Jan. 27, 2017 - Researchers from Tufts University's School of Arts and Sciences, the Allen Discovery Center at Tufts, and the University of Maryland, Baltimore County have had previously shown that pigment cells (melanocytes) in developing frogs could be converted to a cancer-like, metastatic form by disrupting their normal bioelectric and serotonergic signaling and had used AI to reverse-engineer a model that explained this complex process. However, during these extensive experiments, the biologists observed something remarkable: All the melanocytes in a single frog larva either converted to the cancer-like form or remained completely normal. In the new study, the researchers asked their AI-derived model to answer the question of how to achieve partial melanocyte conversion within the same animal using one or more interventions.
The AI model ultimately predicted that a precise combination of three reagents (altanserin, a 5HTR2 inhibitor; reserpine, a VMAT inhibitor, and VP16-XlCreb1, mRNA encoding constitutively active CREB) would achieve that outcome. When this pharmaceutical cocktail was used in vivo on real tadpoles, the result was, in fact, conversion of melanocytes in some regions but not others within individual frog larvae-something never before seen. "Even with the full model describing the exact mechanism that controls the system, a human scientist alone would not have been able to find the exact combination of drugs that would result in the desired outcome. This provides proof-of-concept of how an artificial intelligence system can help us find the exact interventions necessary to obtain a specific result," said the paper's first author, Dr. Daniel Lobo, assistant professor of biology and computer science at the University of Maryland, Baltimore County.
Plans for future research include extending the platform to incorporate time-series data that will enable even more accurate comparisons between computer and in vivo models. Researchers also hope to extend the approach to other aspects of regenerative medicine by discovering interventions that help reprogram tumors, kick start regeneration and control stem cell dynamics. Levin added, "Much of biomedicine boils down to this: We have a complex biological system, and a ton of data on what various perturbations have been seen to do to it. Now we want to do something different--cure a disease, control cell behavior, regenerate tissue. For almost any problem where a lot of data are available, we can use this model-discovery platform to find a model and then interrogate it to see what we have to do to achieve result X."

Jan. 26, 2017 - Malfunctioning microtubules have been associated with various illnesses including cancer and Alzheimer's disease. However, studying a single dynamic microtubule, which measures 24 nanometers in diameter, and up to 10 microns in length, is complicated by established practices of using dyes or stains that are added in order to see the item more clearly, as they can affect the item that is to be scanned in unexpected ways, damaging or even killing biological materials. Researchers in the Quantitative Light Imaging Laboratory at the Beckman Institute, led by Mikhail Kandel, EBICS trainee and lead author on the study, recently published in ACS Nano their technique of using label-free spatial light interference microscopy (SLIM) and computer processing in order to image the microtubules in an assay.
Previous efforts at imaging the miniscule structures have used immunofluorescence, injecting antibodies into fluorescent dyes in order to clearly see the cell as it functions. However, the fluorescence can affect cell function and the length of time that the cell can be imaged. "We imaged them for a very long period of time, not two or three minutes, but more like eight hours," said Kandel. "The label-free aspect is the main breakthrough in my opinion," said Gabriel Popescu, associate professor of electrical and computer engineering. "There have been other efforts towards making this label-free, it's a very important class of challenges. Current techniques yield smaller fields of view, and the image contrast is not as good."
SLIM is a commercially manufactured product that can fit on to upgrade about any microscope, say the researchers. This allows biologists to use other microscopy techniques, including fluorescence, in addition to SLIM. The SLIM product is available through Phi Optics, a company that Popescu founded. The researchers plan to push the boundaries on imaging cells, hopefully imaging microtubules in live cells. "If we manage to push this in a living cell, that would be a real breakthrough," said Popescu.

EBICS Knowledge Transfer in Action!: Kara McCloskey delivers UIUC-developed bio-bot teaching module to UC Merced
Published: January 11, 2017
Jan. 11, 2017 - Kara McCloskey, EBICS faculty member at UC Merced, collaborates with Renuka Nandkishore and Rashid Bashir's lab at UIUC to teach students in her Tissue Engineering Design course to build living, walking robots, aka "bio-bots," out of engineered muscle cells. By harnessing the adaptive response behaviors of biological materials, bio-bots could accomplish more than traditional robots can, due to complex functionalities like self-assembly or self-healing. "Bio-bots have only been around since 2012, so this is really cutting-edge science with multiple technologies - natural materials assembly, 3-D printing, genetic engineering, cell patterning and self-assembly, mechanical force generation - all in a micro-scale platform," McCloskey said.
UIUC developed the bio-bot teaching curriculum and provided the most critical tools, protocols and lecture materials -- the molds for the muscle rings, the 3-D-printed skeletons and the original cell line -- to support delivering the course at collaborating EBICS institutions. McCloskey's UC Merced students are the first from another campus to learn this module as part of their coursework. In learning to assemble cells into functional tissue, McCloskey's students culture the cells in soft, gelatin-like polymers called hydrogels. They pattern the cells in the gel so they will self-assemble into muscle rings, attach the rings to 3D-printed "bones" to create the 7-millimeter-long, light-responsive bots, and then exercise biological machines to build strength called contractile forces.
With an altered design, the bio-bots could be customized for specific applications. Researchers in McCloskey's School of Engineering lab are using similar technology to pattern stem cell-derived heart cells into a sheath of living cardiac tissue that could patch areas of human heart muscle that have been damaged by heart attacks. The sheath would contract and expand just like natural tissue does, in rhythm with the heart. But they must figure out how to integrate patterned synchronously contracting muscle with vasculature to supply blood, and so far, the two have not integrated well.
Ritu Raman, EBICS postdoctoral fellow at UIUC helped design and co-lecture the bio-bot course, focusing on teaching students how to use 3-D printers to design and build their own biological machines. "We see many potential applications for bio-bots ranging from healthcare to national defense to environmental cleanup," Raman said. However, the focus of the curriculum isn't on applications, but on teaching future engineers the fundamental design rules and principles of building with biology. "We want to introduce biological materials into the toolkit of the next generation of makers by giving them hands-on experience with bio-bot design and manufacture," Raman said.

Prof. Laurie Boyer leads Journal Club discussion on "Developmental Engineering of Cell Fate Decisions"
Published: December 12, 2016
Dec. 12, 2016 - MIT hosted Journal Club where the EBICS community across 7 of its affiliated institutions and organizations tuned into Prof. Laurie Boyer's discussion of two papers "Mapping the Pairwise Choices Leading from Pluripotency to Human Bone, Heart, and Other Mesoderm Cell Types" and "Tissue Mechanics Orchestrate Wnt-Dependent Human Embryonic Stem Cell Differentiation" to illustrate the importance of developmental engineering of cell fate decisions. In the context of EBICS, developmental engineering determines parameters that underpin generations of specific and homogeneous cell types, allows identification of key markers for quantifying in vitro emergent behavior in real time, and provides a critical roadmap, both for inferring synthetic circuits driving cell specification and for generating functional 3D-cell systems.
From "Mapping the Pairwise Choices Leading from Pluripotency to Human Bone, Heart, and Other Mesoderm Cell Types," Boyer highlighted:
- Stepwise map of competing signals guiding mesoderm development
- Efficient human mesoderm induction by blocking formation of unwanted fates
- ESC-derived human bone progenitors and heart precursors engraft in vivo
- A transient segmentation program in human embryogenesis marked by HOPX
From "Tissue Mechanics Orchestrate Wnt-Dependent Human Embryonic Stem Cell Differentiation," Boyer highlighted:
- Compliant hydrogel substrates enhance mesoderm differentiation of human ESCs
- Stabilization of adherens junctions primes hESCs for mesoderm differentiation
- Junctional reorganization and Src activity promote nuclear translocation of b-catenin
- On stiff gels, b-catenin degradation inhibits mesodermal differentiation

The research, led by Forrest Goodfellow, a 2012 EBICS REU student and mentored by professor Steven Stice since 2011, presents using a current circulating isolate of Zika virus, MEX1-44, to infect chick embryos, and results are analyzed to develop a neurodevelopmental chick model that could mimic the effects of Zika on the first trimester of pregnancy. This model demonstrates fetal death and brain damage in early chick embryos similar to microcephaly. While high dose infection resulted in embryo death, low dose infections resulted in a decrease in cortical volume. In addition, some embryos displayed structural malformations of the central nervous system, shown in the MRI image (boxed area) of a Zika-infected embryo at embryonic day 20.

Lu Lab exposes masses of hidden traits and possible subtle genetic connections relevant to unseen influences on disease
Published: November 23, 2016
Nov. 23, 2016 - Hang Lu, EBICS faculty member at Georgia Tech, led researchers to develop algorithms and a special microscope slide to expose previously unseen neurological nuances and intricate mutations that may be behind them. Their findings, published in Nature Communications exposes some of the secrets behind gene mutations towards localizing genetic biomarkers for diseases in humans and understanding debilitating disorders, including schizophrenia, bipolar disorder, autism, and autoimmune disorders.
In the Lu lab's latest experiment, researchers track the faintest phenotype changes in roundworms, chosen because their nerves share strong similarities with humans, by marking nerve proteins to appear as dots on roundworms' undersides for the computer to scan. When mutations occur, the dots can change ever so slightly. "To the naked eye, they're just dots on a dark background," Lu said. But the computer sees in them phenotypical shifts.
Lu's technique works via a transparent slide with tiny tubes that suck in one worm at a time under the computer's microscope. The scientists freeze the worm for a moment to take its picture, then unfreezes it. There's a fork in the tube holding the worm. If the algorithm detects a mutant based on its marked pattern in the image - even if this is not visible to the eye - the worm gets sucked down the first path for further study. If it isn't a mutant, it gets sucked down the second path.
Using this technique, the scientists stumbled upon a very subtle allele - a variation of a gene caused by mutation. The worms that had the allele were real mutants, but to the eye, they were completely neat and normal. They even behaved normally at first glance, and the researchers thought the computer may have sorted them out as mutants by mistake -- until a hitch turned up. "After they swam for about 40 minutes, they got really, really weak and couldn't swim well anymore," Lu said. The allele seemed to be associated with some kind of neurological disorder.
"Seen as a metaphor, this is an example of how you might identify something that is relevant to a disease but incredibly subtle," Lu said, "and you would never have found it using eyes and a microscope."

Manu Platt, associate professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory, was recognized by the Atlanta area as one of 40 leaders under the age of 40 who have made significant career achievements and have demonstrated substantial involvement in community service.
One of Professor Platt's mottos is "think globally, act locally, then act globally." This has been enacted in his projects starting with developing a blood test to determine if HIV-positive patients in South Africa were adhering to their antiretroviral medication regimen. Through extension of this work, his lab started projects in Ethiopia, first on HIV-related studies, then later assisting with the training of Ethiopian graduate students to process cancer samples and characterize differences between tumors.
At Georgia Tech, Platt has been hosting and mentoring high school students working in his lab under the Project ENGAGES (Engaging the Next Generation At Georgia Tech in Engineering and Science) program - now in its fourth year. This is a high school research program started with Professor Emeritus Bob Nerem that has brought through 60 African-American students from the Atlanta Public School system.

Popescu and Gillette Labs collaboration develop new imaging method to analyze dynamics of cellular systems
Published: October 26, 2016
Led by professor Gabriel Popescu and professor Martha Gillette, researchers at their respective labs, including former EBICS trainees Ru Wang, Basanta Baduri, Shamira Sridharan, Mustafa Mir, and Raj Iyer, developed a dye and chemical-free imaging method, phase correlation imaging (PCI), to track cells over long periods of time. PCI uses only light to reveal dynamics and provide insight into how cells function, develop and interact.
The study, published in Scientific Reports also uses PCI to look at how elements of the cell's internal skeleton structure guide transportation within the cell. Cells and their internal structures are transparent so researchers commonly use chemicals, like colored or fluorescent stains, to see structures inside cells, but chemicals can disrupt activity, or even poison the cell, and only work for a limited time, making it difficult to track normal cellular activity.
Because PCI only uses light, the researchers can scan a cell culture over and over, creating a timeline of movement within the cell and highlighting hotspots of activity. They can also tell the difference between quiescent cells, cells that are dormant but can become active again when stimulated, and senescent cells, older cells that have stopped dividing. The distinction is important, because quiescent cells are crucial for healing and repair after injury, but are difficult to see without specific chemical labels.
The researchers are now applying PCI to study neurons. They hope to witness emergent behavior, such as neurons in a culture beginning to talk to each other and stem cells developing into neurons. Later on, they plan to apply these dynamic maps to large tissues, such as embryos, brain slices and whole organisms, like worms, to watch development.

Stice Lab produces neurodevelopmental model with potential to accelerate research on Zika-related birth defects
Published: October 19, 2016
Forrest Goodfellow, a 2012 EBICS REU student and mentored by professor Steven Stice since 2011, has been leading a team at University of Georgia's Regenerative Bioscience Center (RBC) since 2015 to develop a neurodevelopmental chick model that could mimic the effects of Zika on the first trimester of pregnancy. This model demonstrates fetal death and brain damage in early chick embryos similar to microcephaly -- a rare birth defect linked to the Zika virus, now alarming health experts worldwide.
Chick embryos have significant similarity to human fetal neurodevelopment and rapid embryonic process: "We wanted a complete animal model, closely to that of a human, which would recapitulate the microcephaly phenotype," said Goodfellow, who has worked extensively with eggs and chickens. In a previous project with Stice and Dr. Qun Zhao, the team developed a unique approach of marrying stem cell biology and MRI to track and label neural stem cells. Using the neurodevelopment chick model, researchers can take a closer look at a multitude of different Zika strains and possibly identify the critical window of susceptibility for Zika virus-induced birth defects, allowing further design and testing of therapeutic efficacy.
Goodfellow presented the findings at the 2016 Southern Translational Education and Research (STaR) Conference. The team's research was also recently featured on WSB-ATL (ABC) news, and the team will be designing the cover of Stem Cells and Development's November 2016 issue.

Aug. 8, 2016 - Brian Williams defended his dissertation "Low Reynolds Number Biohybrid Swimming" at the University of Illinois Urbana-Champaign in front of advisor, Taher Saif, and the rest of his defense committee Hyunjoon Kong, Rhanor Gillette, and Gabriel Juarez.
In Saif Lab, Williams built multicellular biohybrid machines with networks of neurons and myocytes, including a flagellar swimmer that uses the contractions of one to several cardiac myocytes to generate propulsion at low Reynolds number. To achieve the goal of using the complex internal machinery of the eukaryotic cell to build programmable, self-powered, biohybrid robotics, Williams also microfabricated characterizable, compliant platforms to probe specific biological mechanisms, such as the role of mechanical coupling in the collective behavior of large populations of cardiac myocytes. Finally, he analyzed and studied vesicle dynamics in various cell types, and used their transport characteristics to probe the intracellular environment.
Williams was one of EBICS's most prolific developers of outreach demonstrations, used in community events in Champaign, to present core EBICS research concepts, highlights of which include the soft robotics inchworm, the optogenetic bot, and most recently, the Elementary Braitenberg vehicle.
Congratulations to Dr. Brian Williams, who is currently a mechanical engineer at Lam Research in Portland Oregon, and we wish him great success as he moves forward in his career!

Aug. 3-4, 2016 - The 1st International Workshop on Engineering Living Systems convened a cadre of 60 forward-looking thought-leaders across a variety of expertise including: industry, stem cell biology, developmental biology, synthetic biology, tissue chip engineering, robotics, and ethics, whose primary goal is the exploration of the ethical and research implications that arise from the EBICS mission to develop the capability to design, engineer and produce complex integrated cellular systems or "biological machines" that solve real-world problems in health, security, and the environment.
Critical to the successful design of such engineered cellular systems is a fundamental understanding of the interactions between cells and their environment, their control by biochemical and mechanical cues, and the coordinated behavior of functional cell clusters. Examples range from biological robots to organs-on-a-chip, and have broad applications across medicine, manufacturing, agriculture, and energy management, among other disciplines. Whether we achieve this through a "bottom-up" or a "top-down" approach, the basic cellular building blocks can all be derived from pluripotent sources.
In discussing the ethical and research implications of these complex biological interactions, the emergent behaviors they produce, and the ultimate creation of biological machines engineered to perform specific, targeted functions, 2016 Workshop participants agreed to leverage the following broader impacts:
- A position paper on Engineered Living Systems for wide dissemination
- A proposal for a new EFRI call on:
- Advanced manufacturing processes for multicellular machines
- Reduced functionality cells for ELSs
- New collaborations and potential partnerships
- Avenues for continuing EBICS activities
- Transitioning to a regular meeting (e.g. GRC)
- Possibility for a new journal
- Recruiting EBICS Distinguished Visiting Scholars
- Forging new international collaborations (a "virtual center")
- Providing trainees a broader perspective of EBICS-centric activities worldwide
The Workshop on Engineering Living Systems will tentatively next assemble in 2018.

Sebastien Uzel led development of a microfluidic device that replicates the connection between muscles and nerves
Published: August 3, 2016
Aug. 3, 2016 - During his graduate studies at MIT, Sebastien Uzel, now a postdoc at Harvard, led the work on creating a quarter-sized microfluidic device, that allows researchers to influence and observe the interactions between the muscle tissue and motor neurons within a realistic, three-dimensional matrix.
Previously, to simulate the neuromuscular junction in the lab, researchers grew muscle and nerve cells in shallow Petri dishes or on small glass substrates. To recreate more realistic in vitro neuromuscular junctions, Uzel and his colleagues, which includes EBICS faculty Prof. Roger Kamm, Prof. Laurie Boyer, and former EBICS trainee Vincent Chan, fabricated two important features in their microfluidic device: a three-dimensional environment, and compartments that separate muscles from nerves to mimic their natural separation in the human body. The researchers suspended muscle and neuron cells in the millimeter-sized compartments, which they then filled with gel to mimic a three-dimensional environment.
The research results, published online in Science Advances, may help scientists understand and identify drugs to treat amyotrophic lateral sclerosis (ALS), as well as other neuromuscular-related conditions, and could even be tailored to individual patients.
Sebastien and his coauthors have submitted a patent application for their microfluidic device.
