Abstract

Hematopoietic stem cells (HSCs) generate blood and immune cells. Here, we present a protocol to differentiate human pluripotent stem cells (hPSCs) into hematopoietic progenitors that express the signature HSC transcription factors HLF, HOXA5, HOXA7, HOXA9, and HOXA10. hPSCs are dissociated, seeded, and then sequentially differentiated into posterior primitive streak, lateral mesoderm, artery endothelium, hemogenic endothelium, and hematopoietic progenitors through the sequential addition of defined, serum-free media. This 10-day protocol enables the manufacturing of blood and immune cells in monolayer cultures. For complete details on the use and execution of this protocol, please refer to Fowler and Zheng et al.1.
