A seminar hosted by the School of Cellular and Molecular Medicine

The goal of our research is to understand the molecular mechanisms that control early human development. The mechanisms that regulate early cell fate decisions in human development remain poorly understood, despite their fundamental biological importance and wide-reaching clinical implications for understanding infertility, miscarriages, developmental disorders and therapeutic applications of stem cells. We seek to uncover when and how human embryonic epiblast cells are established and maintained, and to understand the molecular mechanisms that distinguish these pluripotent cells from extra-embryonic cells during embryogenesis. We will further develop pioneering methods to investigate gene function during human embryogenesis using CRISPR-Cas9-mediated genome editing, TRIM-Away protein depletion, constitutively active and kinase dead variants of proteins and small molecule inhibitors and activators. These approaches will enable us to directly test the function of genes involved in signalling pathways, and key transcription factors downstream of these pathways, which we hypothesize are involved in the first and second cell fate decision in humans. Altogether, we seek to make significant advances in our understanding of the molecular programs that shape early human embryogenesis, which has the potential to provide fundamental insights and to drive clinical translation.
