Embryonic Stem Cells: Self-renewal and Early Commitment |
Our team examines the mechanisms of self-renewal and pluripotency in mouse and human embryonic stem cells. We aim to identify novel genes involved in the maintenance of the undifferentiated state and in early commitment towards ectodermal, mesodermal and endodermal lineages. Another aspect of our work focuses on the regulation of the cell cycle, which shows unusual characteristics in pluripotent stem cells. We explore the role of regulators of the G1- to S-phase transition in the maintenance of the undifferentiated state. We also make use of the peptide aptamer technology to create novel recombinant proteins supporting self-renewal of human ES cells. | |
