hematopoiesiaa
Hematopoiesis refers to the biological process by which all types of blood cells are produced and developed from multipotent stem cells. This continuous process occurs primarily in the bone marrow, though it begins in the yolk sac during early embryonic development and later shifts to the liver and spleen before returning to the bone marrow in later stages of fetal development. In adults, hematopoiesis is confined mainly to the axial skeleton, including the ribs, vertebrae, pelvis, and sternum, where the marrow is rich in hematopoietic stem cells (HSCs).
The process begins with hematopoietic stem cells, which are capable of self-renewal and differentiation into various
Hematopoiesis is tightly regulated to maintain a balanced production of blood cells, ensuring adequate oxygen transport,
Research into hematopoiesis continues to advance, with insights into stem cell biology contributing to therapies for
