We study embryonic stem (ES) cells and derivative tissue stem cells. Our goal is to understand the molecular foundations of self-renewal and commitment. We are investigating determinants of the decision to retain or exit pluripotency and the mechanism of lineage choice. We are also interested in the relationship between stem cell lines propagated in culture and progenitor cells in vivo. We are analysing the degree of conservation between pluripotent cells from different mammalian species in order to determine whether there are generic principles underlying embryonic stem cell properties. We hope to apply the knowledge gained to control the derivation, expansion and differentiation of human stem cells. We interact with clinical scientists and bioindustry to facilitate uptake and use of stem cells in the study of disease mechanisms and for drug discovery.
