Research Description

The Cosgrove research group is broadly interested in understanding how stem cells use the integrative action of their regulatory circuitry to interpret and balance diverse streams of microenvironmental “information.”  We utilize mouse model systems that exhibit aging-related declines in regenerative capacity, including skeletal muscle, liver, and hematopoietic tissues. In particular, we focus on these main areas of investigation:

(1) We engineer biomimetic microenvironments for evaluating stem cell–niche interactions.

(2) We develop single-cell assay and modeling approaches to deconstruct how stem cell fate outcomes are dictated by diverse niche microenvironmental cues. In particular, we focus on elucidating how heterogeneous stem cell fate outcomes emerge from deterministic signaling and regulatory circuits.

(3) We deconvolve the logic-based communication networks of overlapping autocrine and paracrine signals used by stem cells to communicate with their surrounding microenvironment.

These approaches will enable the improvement of rationally designed, quantitatively predictable stem cell-targeted regenerative medicine therapies to treat tissue aging and degeneration.
