The range of known purified and cloned growth factors and their target cells within the megakaryocytic lineage is described. Data are reviewed outlining that megakaryocytopoiesis appears to be controlled at two levels: (i) by feedback control via circulating factors, and (ii) by factors within the marrow itself. Hypotheses are presented about the nature of thrombopoietin, its relationship to known growth factors, especially Interleukin-6 (IL-6), and the specificity of a thrombopoietic response following change in the circulating platelet mass.

UI	MeSH Term	Description	Entries
D008533	Megakaryocytes	Very large BONE MARROW CELLS which release mature BLOOD PLATELETS.	Megakaryocyte

D001792	Blood Platelets	Non-nucleated disk-shaped cells formed in the megakaryocyte and found in the blood of all mammals. They are mainly involved in blood coagulation.	Platelets,Thrombocytes,Blood Platelet,Platelet,Platelet, Blood,Platelets, Blood,Thrombocyte
D002454	Cell Differentiation	Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs.	Differentiation, Cell,Cell Differentiations,Differentiations, Cell
D006133	Growth Substances	Signal molecules that are involved in the control of cell growth and differentiation.	Mitogens, Endogenous,Endogenous Mitogens
D006410	Hematopoiesis	The development and formation of various types of BLOOD CELLS. Hematopoiesis can take place in the BONE MARROW (medullary) or outside the bone marrow (HEMATOPOIESIS, EXTRAMEDULLARY).	Hematopoiesis, Medullary,Haematopoiesis,Medullary Hematopoiesis
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D013926	Thrombopoietin	A humoral factor that stimulates the production of thrombocytes (BLOOD PLATELETS). Thrombopoietin stimulates the proliferation of bone marrow MEGAKARYOCYTES and their release of blood platelets. The process is called THROMBOPOIESIS.
