In the early 1990s, my lab derived ES cells from an Old World monkey (the rhesus macaque) and a New World monkey (the common marmoset), work that led to derivation of human ES cells in 1998. Much of my lab’s research after that derivation was dedicated to establishing human ES cells as an accepted, practical model system. To that end, we developed defined culture conditions, methods for genetic manipulation, and approaches for the in vitro differentiation of human ES cells to key lineages of clinical importance including hematopoietic, neural, cardiac, and placental tissues., In 2007, my laboratory described the isolation of human induced pluripotent (iPS cells) cells with the basic properties of human ES cells but derived from somatic cells.
My research now focuses on understanding how a cell can maintain or change identity, how a cell chooses between self-renewal and the initial decision to differentiate, and how a differentiated cell with limited developmental potential can be reprogrammed to a pluripotent cell.
My current research interests include:
- Understanding clocking mechanisms that control developmental rates.
- Studying differentiation of vascular progenitors for transplantation therapies
- Examining the transcriptional networks in ES cells that mediate self-renewal and commitment to each of the basic lineages of the early embryo.
- Developing new strategies to convert human pluripotent stem and somatic cells into hematopoietic, vascular, and cardiac progenitor cells. /ul>
