Haematopoietic stem cells (HSCs) reside in the medulla of the bone (bone marrow) and have the unique ability to give rise to all of the different mature blood cell types and tissues. HSCs are self - renewing cells: when they proliferate, at least some of their daughter cells remain as HSCs, so the pool of stem cells is not depleted. This phenomenon is called asymmetric division. The other daughters of HSCs (myeloid and lymphoid progenitor cells) can follow any of the other differentiation pathways that lead to the production of one or more specific types of blood cell, but can not renew themselves. The pool of progenitors is heterogeneous and can be divided into two groups; long - term self - renewing HSC and only transiently self - renewing HSC, also called short - terms. This is one of the main vital processes in the body.
