[cid:image003.jpg@01D9FAB9.71DE0610] BME WEEKLY ROUNDTABLE WEEK OF October 9, 2023 OCTOBERBREAK! INTERIM HEAD'S NOTE To everyone, please enjoy your Octoberbreak. We have finally gotten some autumn weather. Fall has always been my favorite season. The time when everything bursts with its last beauty as if nature had been saving up year for the grand finale. Did you go to the Feast of the Hunters' Moon? If you did, I hope you enjoyed some time off with family and friends. Sweater weather is better together. We are now getting together to go through the thick of the semester which has been crazy so far with the many events and activities in September. Now we are getting together to show our presence at BMES later this week. I want to send my special thanks to Vitaliy, Cindy, and Asem who have worked hard to get everything ready. Thanks in advance to Cindy, Sandy, Tammy, Asem, Darshini, Luke, and Siting for setting up our booth and staying at our booth during the reception on Wednesday. If you plan to attend the Reception on Wednesday, please stop by our booth during the reception (BMES Booth 800). Thank you for all of you who will serve at our booth during the conference. Travel safely, everyone. UPCOMING IMPORTANT DATES Week of October 9 Mon., Oct. 9 - Tues., Oct. 10: Our semi-annual air handling shutdown is tentatively scheduled for Tuesday, October 10th. As a reminder: the entire building air handling system in MJIS will be turned off. ALL chemical hood activity, biosafety cabinet activity, autoclave work and activities in wet labs will need to STOP by 5 PM on Monday, October 9th. Any chemicals stored in the hoods will have to be sealed at that time. Signs will be posted on all hoods to remind users not to use the hoods Monday evening, and removed when the maintenance work is completed and normal operations can resume. Please plan ahead - DO NOT use chemicals in the lab areas that you would normally use in the hoods.

Kyung Sung, Chief of Cellular and Tissue Therapy Branch, Office of Cellular Therapy and Human Tissue, Center for Biologics Evaluation and Research, U.S. Food and Drug Administration, will present "Advanced analytical methods for Assessing the bioactivity of regenerative medicine cellular products." Abstract: Multipotent stromal cells (MSCs) have become popular sources for manufacturing regenerative medicine cellular products due to their ability to undergo lineage-specific differentiation. MSCs, on the other hand, are heterogeneous and responsive to their surroundings, resulting in distinct subpopulations of cells with potentially different properties required for product functional bioactivity. Because there are numerous biochemical and biomechanical factors that influence MSC function, developing reliable high-throughput assays that allow for the efficient exploration of large and complex parameters for evaluating cellular function is critical. Microphysiological systems offer a viable solution to this unmet need. This presentation will provide an overview of regenerative medicine cellular product regulation as well as easy-to-use, microscale technologies that improve throughput, relevance, and reliability. How such technologies could be used to evaluate the efficacy of regenerative medicine cellular products will also be discussed. Biography: Dr. Kyung Sung is the Chief of the Cellular and Tissue Therapies Branch in the Office of Cellular Therapy and Human Tissue at the Center for Biologics Evaluation and Research, U.S. Food and Drug Administration. In addition to overseeing regulatory science research programs, she is responsible for overseeing the regulatory review process for cell and tissue therapeutic products and medical devices. Her research team studies the effects of interactions between living cells and biomaterials by developing novel quantitative assays using a variety of biomedical engineering tools. The overarching goal is to understand how these interactions affect the production and characterization of regenerative medicine cellular products. She earned her Ph.D. in Chemical Engineering from the University of Michigan, Ann Arbor, and completed her postdoctoral training at the University of Wisconsin, Madison. Before joining the FDA in 2015, she had experience working as a patent examiner in Biotechnology at the US Patent and Trademark Office. ~ BME Host: Young Kim ~ Zoom link: https://purdue-edu.zoom.us/j/5593290378?pwd=eFBOZFlNTU50ZDA2S2gwcnpyOWIwUT09<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpurdue-edu.zoom.us%2Fj%2F5593290378%3Fpwd%3DeFBOZFlNTU50ZDA2S2gwcnpyOWIwUT09&data=05%7C01%7Cbmeroundtable-list%40ecn.purdue.edu%7C0db8652b2d94403b439f08dbc8f21c49%7C4130bd397c53419cb1e58758d6d63f21%7C0%7C0%7C638324715187454665%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=pJu2ZMXZDAT0ZYY0hL8DLXuTUaEcHGOmnfX0Fg7sVds%3D&reserved=0> Note: Students registered for the seminar are expected to attend in-person.

Research title: Ultrahigh-Resolution Imaging and Quantitative Analysis Through Brain Tissue with High Accuracy. Thesis Committee members: Fang Huang, Chair; Alexander A. Chubykin; Daniel M. Suter; Kevin J. Webb Abstract: 4Pi single-molecule localization microscopy (4Pi-SMLM) enables the revealing of ultrastructure by combining interferometric coherent fluorescence imaging and single-molecule localization. Current methods model the interferometric point spread function (PSF) by scanning in-vitro beads on coverslips to infer in-situ 3D location of single-molecule fluorophores in specimens. Although a resolution of sub-20-nm throughout the whole cell has been achieved, imaging tissue specimens was impeded by the heterogeneous aberration and scattering in tissue environment. Here, we introduce 4Pi in-situ PSF retrieval method (4Pi-INSPR), which allows 12-nm-resolution visualization and quantitative analysis through brain tissue with high accuracy. 4Pi-INSPR incorporates sample-induced aberrations, previously unattainable by conventional 4Pi-SMLM. 4Pi-INSPR also minimizes reconstruction artifacts from instrumental imperfections such as objective and imaging-quadrant misalignments. We demonstrate 4Pi-INSPR capabilities by revealing the ultrastructure of dendrites and dendritic spines in 50-μm mouse brain sections and quantifying their morphology changes and nanoscale molecular distribution. Together, 4Pi-INSPR provides potential in examining synaptic functions for brain development. Thurs., Oct. 12: BME PhD Preliminary Exam Announcement for Donghyun Yim (T. Kim, advisor).

Advisory Committee: Taeyoon Kim, Chair; Adrian Buganza-Tepole; Daniel M. Suter; Qing Deng Abstract: Directional cell migration is the essential ability of many cells and occurs in the guidance of different types of cues, including substrate stiffness, surface topology, and chemoattractant gradient. In particular, when the external chemotactic stimuli are present, chemoattractant successively activates signaling pathways in the cell, followed by the nucleation and polymerization of actin filaments (F-actins). As a result, F-actin establishment and protrusion are biased at the sites with the maximal concentration of chemotactic cues, leading to migration toward chemoattractant. For the migration, formation of focal adhesions between the cell and an extracellular environment is necessary. Chemotaxis has been studied in various computational studies. However, to our knowledge, the computational model of chemotaxis considering the dynamics of F-actins and focal adhesions still lacks. To address this gap, we introduce a two-dimensional cell migration model comprising nucleus, membrane, F-actins, and underlying substrate. In this model, it is assumed that the elongation rate of an individual F-actin is enhanced by the local chemoattractant level in order to capture the dependence of the F-actin polymerization rate on the chemoattractant concentration. Repulsive forces act between F-actin and the membrane to simulate the membrane protrusion driven by elongating F-actins. F-actins are allowed to bind to substrate via focal adhesions. In preliminary results, it was observed that a cell located in the middle of a linear concentration gradient for chemoattractant protrudes and then migrates toward the region with higher concentration. We expect the current concept of the model will provide better understanding of F-actin-mediated chemotaxis.

Alves, PhD, within the Department of Emergency Medicine at the Indiana University School of Medicine (IUSM), is seeking a highly motivated and independent post-doctoral research fellow. Dr. Alves is a Chemical and Biomolecular Engineer, Associate Professor and the Director of Translational Research for the Department of Emergency Medicine in addition to having an affiliate faculty appointment at Purdue University in Biomedical Engineering. The Alves Lab explores highly interdisciplinary research interests applying engineering and biophysical principles and designs to create translational technologies and treatments in the area of blood coagulation and fibrinolysis. The primary focus of research in the laboratory is to develop targeted clot digesting therapeutic agents to more safely digest clinically relevant blood clots to treat pulmonary embolism (PE, blood clots in the lungs), deep vein thrombosis (DVT), and ischemic stroke. This interdisciplinary research utilizes diverse enzyme assays, chemical synthesis, blood clot formation and digestion assays under shear, and other novel testing/delivery platforms that include multivalent branched molecules and nanoparticle drug delivery systems. Projects Include: (1) Leveraging multivalency to modulate enzyme activity and improve inhibitor selectivity (nanoparticle drug delivery and targeting). (2) Ex-vivo flowing models of clot digestion under shear using in-vivo like fluorescently labeled blood clots from human whole blood. (3) Development of novel fibrinolytic diagnostics tools to assess coagulation state. (4) Mouse models of clot formation/targeting/digestion utilizing intravital microscopy. (5) Study the effects of environmental microplastic exposure on coagulation/fibrinolysis. Projects are funded both externally and internally.
