The Fischell Department of Bioengineering (BIOE) left a mark at this year’s Society For Biomaterials (SFB) 2023 Annual Meeting and Exposition. On April 19, 2023, senior Blake Kuzemchak and recent alum Erfan Jabari were awarded the SFB 2023 Outstanding Undergraduate Student Research Award and the C. William Hall Scholarship, respectively. Kuzemchak and Jabari have both worked in BIOE Chair Dr. John Fisher’s Tissue Engineering & Biomaterials Lab (TEBL). 

On receiving his award, Kuzemchak said that it felt great to be recognized for his efforts. However, the most valuable part of this experience, he said, was learning to write and publish a lead-author manuscript. It gives him a head start for what is coming in graduate school.

Kuzemchak is interested in studying regenerative medicine and bionics for amputees. Specifically, he wants to develop neural interfaces that take advantage of the regenerative properties of peripheral nerves to make a far more robust nerve recording device than what the field offers now. Amputees could control more advanced bionics with a more natural feel with this new recording scheme. In fact, these neural implants could, in general, allow the average person to interface their nervous system directly with machines rather than through physical touch. 

Kuzemchak enjoyed working in Fisher’s lab and was given a lot of independence after training—a rare opportunity for undergraduate researchers.

“I have an excellent graduate student mentor, Robert Choe, who helped me understand the key principles of tissue engineering and the workflow of research to shape my raw passion into productive research,” he said. “Robert pushed me to be independent and creative in my work, which I used to publish my manuscript. It has been, and continues to be, a rewarding experience working in the TEBL.” 

This project started as proposed by Fisher and turned into one of his projects. His research was on developing a material that mimics the electrical properties of skin that can be 3D printed on demand into complex structures. This can be used to calibrate Bioimpedance Spectroscopy (BIS) devices that take advantage of the electrical properties of tissue to identify skin cancer. Typical natural materials cannot be readily 3D printed to recapitulate complex tissue and tumor geometries, which can often skew results for BIS devices. However, the semi-synthetic material he developed and characterized is 3D printable and maintains similar electrical properties to the skin. 

Jabari is a recent BIOE graduate and has been a member of TEBL since 2019. He has assisted with osteochondral bioprinting studies and completed an honors thesis in bone regeneration. These experiences helped him better grasp the exciting role bioengineering plays in solving medicine’s most complex challenges and reinforced his interest in regenerative medicine.

Jabari noted that to be nominated by Fisher and to receive this scholarship award were exciting accomplishments. It was encouraging for his previous undergraduate thesis and the planned National Institute of Dental and Craniofacial Research (NIDCR)/TEBL post-bac research endeavors to be celebrated by SFB.

“During my junior and senior years, I completed an honors thesis that explored the role of hematopoietic osteoclasts in bone formation as a tissue engineering strategy for defect repair,” he explained. “The human mesenchymal stromal cell/osteoclast coculture system developed in this work elucidates the anabolic coupling capacity of osteoclasts and provides a platform for future investigations of osteoclast-directed bone formation.” 

Jabari plans to utilize the skills he gained from this experience to develop transplantable bone marrow models and investigate hematopoietic stem cell mechanobiology as an NIDCR/TEBL post-bac.

Maryland Engineering’s John Fisher Appointed MPower Professor

Fischell Family Distinguished Professor and Fischell Department of Bioengineering (BIOE) Chair John P. Fisher was named an MPower Professor by the University of Maryland Strategic Partnership: MPowering the State. Fisher is one of three University of Maryland, College Park (UMCP) faculty members to receive the honor along with three University of Maryland, Baltimore (UMB) faculty members. 

Fisher was recognized for both his collaborative research efforts and the key role he played in establishing new connections between the two campuses. On the research front, Fisher most recently worked with cross-campus collaborators in the areas of stem cell culturing and tissue reconstruction for breast cancer patients. As BIOE department chair, Fisher has been instrumental in the establishment of the joint M.D./Ph.D. and M.D./M.S. programs with BIOE and the School of Medicine (UMB), as well as in the launch ofNeuro-Link, an initiative to provide funding support for joint BIOE and Department of Neurosurgery (UMB) research endeavors. 

The MPower Professorship recognizes, incentivizes, and fosters collaborations between faculty who are working together on the most pressing issues of our time. To be considered for the MPower Professorship, faculty must demonstrate collaboration on strategic research that would be unattainable or difficult to achieve by UMB or UMCP acting independently of one another and must embrace the mission of MPower to collaboratively strengthen and serve the state of Maryland and its citizens. 

Each professor will receive $150,000, allocated over three years, to apply to their salary or to support supplemental research activities. These funds recognize, enable, and support strong collaborations between faculty in the joint research enterprise between UMCP and UMB.

Fisher is the second BIOE faculty member in as many years to receive the honor, following Minta Martin Professor of Engineering Christopher M. Jewell in 2021.

“The MPower Professors have shown incredible dedication and commitment to collaboration, innovation and discovery. Their work to solve major challenges and positively impact the lives of others is bolstered by this investment,” said UMB President Bruce E. Jarrell, M.D.

“The six professors selected for this honor are each working across disciplines to address the most complex challenges facing society today, bridging research and scholarship between institutions to foster innovation that will impact citizens in Maryland, across the country, and around the world,” said UMCP President Darryll J. Pines.

As the director of the Tissue Engineering and Biomaterials Lab, Fisher leads his research team in investigating biomaterials, stem cells, bioprinting, and bioreactors for the regeneration of lost tissues – in particular, bone, cartilage, and cardiovascular soft tissues. Fisher’s lab has published more than 200 articles, book chapters, editorials, and proceedings and delivered more than 340 invited and contributed presentations while utilizing more than $15 million in financial support from the National Institutes of Health (NIH), the National Science Foundation, the U.S. Food and Drug Administration, the National Institute of Standards and Technology, the U.S. Department of Defense, and other institutions.

“Healthcare is a multifaceted challenge that requires collaboration from different fields:  clinicians, engineers, scientists, and public health experts partnering on solutions to today’s most pressing challenges. As leaders in the scientific community, we have a responsibility to strengthen the ties that make human health innovation possible. Dr. Fisher is making good on that responsibility,” said Maryland Engineering Dean Samuel Graham, Jr. “We see Dr. Fisher’s dedication to his students, department, and the broader community every day, and we’re fortunate to benefit from his leadership at Maryland Engineering.”

In addition to his BIOE appointment, Fisher is also the director of the Center for Engineering Complex Tissue, an NIH National Institute of Biomedical Imaging and Bioengineering center established to create a broad community that focuses on 3D printing and bioprinting for regenerative medicine applications.

Fisher is an elected Fellow of the American Institute for Medical and Biological Engineering, the Biomedical Engineering Society, and the International Academy of Medical and Biological Engineering. Among his previous awards, he has received the Society for Biomaterials Clemson Award for Contributions to the Literature, the Tissue Engineering and Regenerative Medicine International Society – Americas’ Senior Scientist Award, and a Fulbright Fellowship to study at the National University of Ireland, Galway. Currently, he serves as editor-in-chief of the journal Tissue Engineering, while also editing six texts in the field of tissue engineering. 

Fisher earned a B.S. in biomedical and chemical engineering from Johns Hopkins University in 1995, an M.S. in chemical engineering from the University of Cincinnati in 1998, and a Ph.D. in bioengineering from Rice University in 2003. He completed a postdoctoral fellowship in cartilage biology and engineering at the University of California, Davis in 2003.

The University of Maryland Strategic Partnership: MPowering the State leverages the sizable strengths and complementary missions of both UMB and UMCP to strengthen Maryland’s innovation economy, advance interdisciplinary research, create opportunities for students, and solve important problems for the people of Maryland and the nation. Working together, UMB and UMCP achieve innovation and impact through collaboration.

The University of Maryland Strategic Partnership Act of 2016 strengthened and formalized the structured relationship between UMB and UMCP, which began in 2012. The law deepens the alliance and enables UMB and UMCP to pursue even greater transformative change and impact, far surpassing what each institution could do independently of the other.

Erfan Jabari Receives Winston Family Honors

Fischell Department of Bioengineering (BIOE) senior Erfan Jabari received the 2022 Winston Family Papers Award for Outstanding Honors Thesis during the University of Maryland (UMD) Honors College Citation Ceremony on Friday, April 29.

Established by Roger (’76, ’79) and Karen Winston (’75), the annual UMD Winston Honors Writing Awards recognize the best essays, research papers, and theses written by honors students.

Erfan, an undergraduate researcher in BIOE professor John Fisher’s Tissue Engineering & Biomaterials Laboratory, focused his thesis on critically-sized bone defect repair in orthopedic medicine.

“Bone tissue is naturally able to repair damage and regenerate completely, but medical intervention becomes necessary when a defect’s size is too large,” Jabari said. “Bone grafts – the current treatment option – are limited in supply and pose a significant risk of donor site morbidity or immune rejection. Bone tissue engineering aims to address these shortcomings by developing synthetic constructs that coordinate biomaterials, cells, and bioactive signals to facilitate tissue repair.”

In bone tissue engineering, mesenchymal bone-forming cells have been explored thoroughly as a tool for defect repair, he noted. The role of osteoclasts – their bone resorbing counterpart – has not been investigated as extensively. Recent bone physiology research shows, however, that osteoclasts have an interesting ability to interact with bone-forming osteoblasts and mesenchymal stem cells (MSCs) through a variety of mechanisms to stimulate bone formation. Motivated by this concept, Jabari and fellow members of Fisher’s lab sought to develop a system whereby osteoclast-directed bone formation could be observed and investigated for bone tissue engineering purposes.

“In this effort, we successfully developed a 2D coculture model of human MSCs and peripheral blood-derived monocytes (progenitors of osteoclasts),” he said. “Our system shows that bone formation is enhanced in conditions where osteoclast development is facilitated, corroborating evidence that osteoclasts support the activity of bone-forming cells. Specifically, we observed known features of osteoclast-directed bone formation such as MSC proliferation and matrix development, and a novel feature – MSC clustering.”

Ultimately, the group demonstrated the potential of osteoclasts in bone tissue engineering to inform future strategies for bone defect repair, Jabari said. The work, which revealed the ability of osteoclasts to induce MSC clustering, also provides an accessible system for further investigation of osteoclast-directed bone formation.

In addition to his Winston Family Honors Award, Jabari was also recently named one of the University of Maryland’s Undergraduate Researchers of the Year.

Jabari plans to graduate in December 2022, after which he hopes to explore an M.D./Ph.D. program.

“I am excited to expand on the experiences the Fischell Department of Bioengineering has granted me, wherever that may be!” he said.
