Hematopoiesis cytokines
WebHematopoietic cytokines are large family of extracellular ligands that stimulate hematopoietic cells to differentiate into eight principle types of blood cells. Numerous … In developing embryos, blood formation occurs in aggregates of blood cells in the yolk sac, called blood islands. As development progresses, blood formation occurs in the spleen, liver and lymph nodes. When bone marrow develops, it eventually assumes the task of forming most of the blood cells for the entire organism. However, maturation, activation, and some proliferation of lymphoid cells occurs in the spleen, thymus, and lymph nodes. In children, haematopoiesis occurs in the …

WebHematopoiesis is the process by which a small pool of self-renewing pluripotent HSCs produce red blood cells, platelets, and all leukocyte types. Only 1 of about 10 000 bone marrow cells is an HSC, 11, 12 and these cells are comparatively quiescent with fewer than 5% of them being in cell cycle at any point in time.
