Hematopoiesis location
WebPurpose of review: The bone marrow is the main site for hematopoiesis. It contains a unique microenvironment that provides niches that support self-renewal and differentiation of hematopoietic stem cells (HSC), multipotent progenitors (MPP), and lineage committed progenitors to produce the large number of blood cells required to sustain life. WebHematopoietic stem cell (HSCs) mainly reside in the bone marrow, where the bulk of hematopoiesis occurs during adulthood. Bone structures that form and protect the medullary cavity are densely innervated and vascularized with the periosteum lining the outer surface and the endosteum coating the inner surface.
