Atkins et al. (2022. J. Exp. Med.https://doi.org/10.1084/jem.20211924) create a PSC differentiation model for human yolk sac hematopoiesis and discover multipotent progenitors with erythro-myeloid and T lymphoid potential. The multipotent progenitors emerge via hemogenic endothelium and share origin with primitive erythroid wave in KDR+CD235a/b+ mesoderm.
