Abstract

Maintenance of hematopoietic stem cells (HSCs) in vitro has been believed to be difficult due to a lack of complete understanding of HSC quiescence maintained by the niche. Recent evidence suggests that in vitro maintenance of human and mouse long-term HSCs (LT-HSCs) is possible through dual inhibition (2i) of both GSK-3 and mTOR in the absence of cytokines, serum, or feeder cells.
