BME Master's Defense Announcement for Clarisse Zigan
(D. Chan, Advisor),
Tues., July 18, 3:00 p.m., MJIS 2001 and via Zoom. Title of presentation: Exploring Changes to Matrix Mechanics and Composition of Chondrocyte-laden
Hydrogels.
Committee: Dr. Deva Chan, Chair; Dr. Alex Chortos, Dr. Douglas Brubaker
Abstract: To explore the mechanisms of cellular mechanotransduction,
it is necessary to employ biomaterials that effectively merge biofunctionality with appropriate mechanical characteristics. Agarose is a standard biopolymer used in cartilage mechanobiology but lacks necessary adhesion motifs for cell-matrix interactions to
complete mechanostransduction studies. Collagen type I is a natural biomaterial used in cartilage mechanotransduction studies but creates an environment much softer than native cartilage tissue. In these studies, agarose is blended at two final concentrations
(2% w/v and 4% w/v) with collagen type I (2 mg/mL). Our ultimate goal is to determine whether a composite hydrogel of agarose and collagen can create a mechanically and biologically suitable matrix for chondrocyte studies. First, hydrogels were characterized
by rheologic and compressive properties, contraction, and structural homogeneity. Following baseline characterization, primary murine chondrocytes were embedded (1 x 106 cells/mL) within the hydrogels to assess the longer-term
in vitro impact on matrix mechanics, cell proliferation, sulfated glycosaminoglycan (sGAG) content, and cellular morphology. To begin probing questions about physiologic loading conditions that chondrocytes experience
in vivo, a custom compression loading system was validated using cell-laden hydrogels.
Briefly, the 4% agarose – 2mg/mL collagen I hydrogel composites were able to retain chondrocyte morphology over
21 days in culture, resulted in continual sGAG production, and had bulk mechanics similar to that of the stiffest hydrogel material tested, indicating this hydrogel class may be promising towards developing an effective hydrogel
for chondrocyte mechanotransduction and mechanobiology studies, a critical step towards a fuller understanding of cell-matrix interactions.

BME Summer Seminar Series,
Wed., July 19,
9:30 a.m., via Zoom. Cameron Villarreal (Deva Chan, advisor) will present “The gut microbiome modulates the structure-function relationship in musculoskeletal tissue: More than a gut feeling.”
Jae Young Park (Hugh Lee, advisor) will present “Novel stretchable thin-film electronic device-based neuromodulation platforms for less risky, easy, and reliable implantation.”
The gut microbiome modulates the structure-function relationship in musculoskeletal tissue: More than a gut feeling,
Cameron Villarreal (Deva Chan, advisor)
Abstract:
The gut microbiome is a diverse and dynamic ecosystem that modulates numerous physiological processes across organ systems. Microbes and microbe metabolites have been shown to alter systemic inflammation,
intestinal permeability, and nutrient metabolism. Each of these processes can be associated with musculoskeletal development and the underlying structure-function relationship in the various connective tissues of the musculoskeletal system. Beyond these indirect
relationships, other work has shown that modulation of the gut microbiome in rodents by introducing a high-fat diet or antibiotics leads to an altered propensity for musculoskeletal diseases like osteoarthritis and altered bone material properties. While a
wealth of evidence suggests that the gut microbiome has a widespread systemic effect in the musculoskeletal system, how it modulates the connective tissue in joints and underlying subchondral bone remains poorly understood hindering our ability to diagnose,
treat, and prevent musculoskeletal disease. Through our work, we aim to examine how deviations from a steady state gut microbiome, or dysbiosis, may result in deleterious changes to bone quality, cartilage content, and markers of systemic inflammation. We
examine alterations to the structure-function relationship in musculoskeletal tissue through a combination of imaging, biomechanics, and content assays. Additionally, we profile the gut microbiome through 16s with the goal of correlating changes in the gut
microbiome to altered gut composition. This work seeks to enhance our understanding of the interrelatedness between the gut and the musculoskeletal system to enable improved treatment, both adjuvant and preventative, of musculoskeletal disease and injury.

Novel stretchable thin-film electronic device-based neuromodulation platforms for less-risky, easy, and reliable implantation,
Jae Young Park (Hyowon Lee, advisor)
Abstract: Neuromodulation is increasingly utilized to rehabilitate a variety of biological functions, such as vision, hearing, movement, touch perception, and sense of self-movement,
particularly in patients with severe or chronic diseases for whom other treatment options, including medication, have proven ineffective. Nevertheless, due to concerns about the cost and safety of surgical processes, many are hesitant to proceed with this
option. Concerns particularly arise from the potential displacement of the electrode caused by movements at the target site due to air infiltration or cerebrospinal fluid loss during surgery. Other issues including technical errors, failure in lead fixation,
Twiddler syndrome, and Pneumocephalus can also result in electrode dislocation. This misalignment can lead to off-target effect that can have severe repercussions for patients. In address these issues, we have developed two novel platforms and accompanying
surgical strategies to enable safer, more accurate, and easier implantation: 1. Flexible electronic catheter for Deep Brain Stimulation (DBS) 2. Adhesive-hydrogel-integrated cuff electrodes for Vagus Nerve Stimulation (VNS). To achieve these multifaceted objectives,
we designed a stretchable thin-film electronic device using polyimide-based microfabrication techniques, which is compliant to other functional medical platforms. By integrating this device with silicone catheter and adhesive hydrogel, we have endowed the
device with new functionality that facilitate novel implantation methodologies.

Trailblazers in Engineering Keynote Lecture,
Wed., July 26, 8:30-9:30 a.m., The Convergence Center, 101 Foundry Dr., Suite 120. Cato T. Laurencin, University Professor at the University of Connecticut and Chief Executive Officer of the Cato T. Laurencin
Institute for Regenerative Engineering at the University of Connecticut will present “Regenerative Engineering: Chemistry and Materials Science in Regeneration.”
Abstract:
We define the field of Regenerative Engineering as the Convergence of Advanced Materials Science, Stem Cell Science, Physics, Developmental Biology, and Clinical Translation
for the regeneration of complex tissues and organ systems. Work in the area of musculoskeletal tissue regeneration has focused on a number of technologies. Polymeric nanofiber systems create the prospect for biomimetics that recapitulate connective tissue
ultrastructure allowing for the design of biomechanically functional matrices, and next generation matrices that create a niche for stem cell activity. Polymer and polymer-ceramic systems can be utilized for the regeneration of bone. Through the use of inducerons,
small molecules fostering induction, the design of regeneration-inducing materials can be realized. Hybrid matrices possessing micro and nano architecture can create advantageous systems for regeneration, while the use of classic principles of chemistry, materials
science, and engineering can lead to the development of three-dimensional systems suitable for functional regeneration of tissues. Work in the creation of synthetic artificial stem cells present prospects for joint restoration. Through convergence of a number
of technologies, we believe the prospect of engaging future grand challenges is possible.

Prospective BME Faculty Seminar,
Mon., July 31, 9:30 a.m., MJIS 1083 or via Zoom. Cheen Euong Ang, Postdoctoral Researcher, Department of Chemistry and Chemical Biology, Harvard University, will present “Illuminating neurobiology and pathology
by cellular reprogramming and spatial omics.”
Abstract: Genome-wide association studies have revealed single nucleotide polymorphism and copy number variants associated with neurological diseases. Generally, mutations in the coding genes
are decipherable based on our knowledge of splicing and the genetic code. However, how mutations in the regulatory elements or non-coding RNAs contribute to neurological diseases remain an open area of investigation. Elucidating how non-coding regions contribute
to pathogenesis is hindered by: (a) the lack of access to healthy or diseased human brain tissue samples and (b) the lack of tools to visualize the spatial activity of regulatory elements and non-coding RNAs within the nucleus and across brain tissue and how
their spatial activity regulates gene expression.
In the first part of my talk, I will describe the development of reprogramming protocols to obtain human neurons via direct conversion of somatic or embryonic stem cells into induced neurons
and the use of those neurons to model a non-coding RNA mutation found in autism spectrum disorder patients. Additionally, I will present my recent work in developing spatial transcriptomic and epigenomic imaging methods to shed light on gene regulation and
enhancer dynamics during nervous system development. The research presented showcases the promise of using neuronal reprogramming and spatial imaging to deepen our understanding of neurodevelopmental processes and
the role of non-coding mutations in neurological diseases, potentially informing the future development of new therapeutic strategies.
