where does myeloid hemopoiesis take place in adults
Haematopoiesis 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.[1] HSCs are self-renewing cells: when they differentiate, 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.[4]  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 cannot 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.[5] This is one of the main vital processes in the body.
Aplastic anemia Aplastic anemia is a rare disease in which the bone marrow and the hematopoietic stem cells that reside there are damaged.[1] This causes a deficiency of all three blood cell types (pancytopenia): red blood cells (anemia), white blood cells (leukopenia), and platelets (thrombocytopenia).[2][3] Aplastic refers to inability of the stem cells to generate mature blood cells.
