Engineering Cells and Their Microenvironments 1 (SIG)
Timeslot: Thursday, April 28, 2022 - 2:45pm to 4:45pm
Room: Harborside Ballroom D-E, 4th Floor
The Engineering Cells & Their Microenvironments Special Interest Group focuses on approaches to alter cell microenvironments. These approaches can be used to control biomaterial-induced cell signaling to enable stem cell manufacturing and differentiation, immunoengineering, as well as for the development of biomaterials for cell-based detection and diagnosis. These biomaterial-based approaches can also be utilized to direct cellular responses (e.g., proliferation, differentiation, morphological regulation, motility, matrix production) without the addition of external growth factors, chemicals, or drugs, thereby mitigating potential side-effects and facilitating improved in vitro and in vivo cellular outcomes. This session will focus on translation of these techniques toward a variety of specific applications ranging from, but not limited to, tissue engineering for dynamic disease models and regenerative medicine to therapeutics and direction of stem cell differentiation. Studies that develop biomimetic materials which provide specific physicochemical cues (e.g., composition, topography, stiffness) to achieve a desired cellular response will also be highlighted.
Abstracts will be available for download on April 27, 2022.
