Our lab focuses on stem cell biology, with an emphasis on somatic cell reprogramming, hematopoietic differentiation from human and mouse pluripotent stem cells, and the role of the Lin28/let-7 pathway in human cancer and metabolic disease. Our subgroups study:

• The differentiation of hematopoietic (blood producing) stem cells from embryonic and induced pluripotent cells. We study hematopoietic development in mouse embryos and in human and mouse pluripotent stem cells to define the molecular genetic programs that enable formation of HSCs in experimental and therapeutic models.

• Derivation of personalized, patient-derived pluripotent stem cells: We use nuclear transfer, parthenogenesis, and reprogramming with defined genes to model combined cell and gene therapy of human genetic disorders.

• The Lin28/let-7 pathway: We have linked this ancient pathway, originally discovered in heterochronic mutants in C. elegans, to human cancer, germ cell development, and regulation of human growth and developmental timing. The pathway is also important in the function of stem cells, and in linking cancer cell proliferation and cellular metabolism.
