Developmental regulation of endothelial-to-hematopoietic transition from induced pluripotent stem cells.

ABSTRACT: Hematopoietic stem cells (HSCs) arise in embryogenesis from a specialized hemogenic endothelium (HE) via endothelial-to-hematopoietic transition (EHT). While induced pluripotent stem cells (iPSCs) give rise to HE with robust hemogenic potential, bona fide HSC generation from iPSCs remains challenging. We map single-cell dynamics of EHT from iPSCs and integrate it with human embryo datasets to identify ligand-receptor interactions that drive transcriptional divergence between iPSC-derived and embryonic cell states. The expression of endothelial genes predicted to be regulated by FGF signaling was incompletely repressed during iPSC-derived EHT. FGF activity declined at the onset of EHT to enable normal hematopoiesis in the zebrafish, and chemical inhibition of FGF signaling during EHT enhanc
