Small-molecule inhibitors targeting INK4 protein p18INK4C enhance ex vivo expansion of haematopoietic stem cells

摘要

The cyclin-dependent kinase inhibitors p18 and p27 confer advantage to the propagation of haematopoietic stem cells (HSCs). In this manuscript, the authors demonstrate that p18 is a potent negative regulator of HSC self-renewal, and identify novel small molecules putatively inhibiting p18 that promote HSC growth in culture and mouse transplant assays.
