Identifying novel regulators of human pluripotency and embryogenesis 

The mode of specifying pluripotent human epiblast (hEPI)is unclear and may differ from the mouse. Recent advances in single-cell techniques have allowed investigation of gene and transcriptional networks in human pre-implantation development. Numerous transcription factors (TFs), including KLF17, VENTX and ARGFX, are enriched in hEPI, upregulated in “naïve” hESCs, but absent in mouse blastocysts. I am investigating the role of theseTFs in pluripotency in hESCsthrough both loss- and gain-of-function studies, aiming to define human-specific pluripotency regulators acting in vitro and in vivo.
