My research uses embryonic and induced pluripotent stem cells as genetic and developmental models, tools for genetic engineering of the mouse, and as reagents for regenerative medicine. My group is interested in understanding the signaling pathways and genetic hierarchies that regulate gene expression, stem cell self-renewal, and differentiation in pluripotent stem cells. A major project seeks to understand the function of TGF-beta-related signaling pathways in stem cell self-renewal. These efforts have uncovered important and previously uncharacterized roles for the Nodal and BMP signaling pathways in the dynamic heterogeneity that exists in pluripotent cells.
My group makes substantial use of mouse embryonic stem cells for genetic engineering to generate transgenic and mutant mice, for the development of animal models of congenital diseases mapped by human genetics studies. I have a sustained interest in developing novel strategies to generate mutant and transgenic animals to support these studies. These efforts leverage our knowledge of both stem cell and developmental biology.
A major focus of my group also involves the development of pluripotent stem cells and genetically modified mice for modeling rare undiagnosed neurodegenerative disorders. We use patient-specific induced pluripotent stem cell models and genetic modification of the mouse via genome editing to study novel variants identified in these patients.
Another area of interest involves the development of cellular therapies for spinal cord injury using human pluripotent stem cells differentiated to specific neural sublineages. This work makes use of novel engineering strategies for introducing reporters into human iPS cells to monitor directed neural differentiation, and for use in high-throughput screens.
