Regulation of hematopoietic stem cells in the niche

Sci China Life Sci. 2015 Dec;58(12):1209-15. doi: 10.1007/s11427-015-4960-y. Epub 2015 Nov 13.


Hematopoiesis provides a suitable model for understanding adult stem cells and their niche. Hematopoietic stem cells (HSCs) continuously produce blood cells through orchestrated proliferation, self-renewal, and differentiation in the bone marrow (BM). Within the BM exists a highly organized microenvironment termed "niche" where stem cells reside and are maintained. HSC niche is the first evidence that a microenvironment contributes to protecting stem cell integrity and functionality in mammals. Although multiple models exist, recent progress has principally elucidated the cellular complexity of the HSC niche that maintains and regulates HSCs in BM. Here we introduce the development and summarize the achievements of HSC niche studies.

Keywords: hematopoietic stem cells; niche; regeneration.
