There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

ABSTRACT
An improved understanding of how stem cells interpret signals from engineered environments is integral to developing better cell therapies. The organization of numerous intracellular components is tightly regulated by the same outside-in signaling events that control cell behavior. In this talk, I describe an imaging-based framework to classify single cell responses to engineered environments. I will first show how we used the spatial organization of nuclear speckle domains to classify stem cell responses to stimulatory soluble factors, surface patterns, and microscale topographies. I will then discuss our work on developing protease-degradable hydrogels to investigate how dimensionality affects mechanotransduction. Lastly, I will present our recent efforts on designing combinatorial hydrogels in tandem with single cell analysis to create hydrogel environments that promote stem cell differentiation into cartilage-producing chondrocytes. The work presented here has the potential to identify signals for developing stem cell environments with broad applications in regenerative medicine.
