A Hormone That Stimulates Production of Granulocytes and Monocytes Is

Question

A hormone that stimulates production of granulocytes and monocytes is
A) M-CSF.
B) G-CSF.
C) GM-CSF.
D) multi-CSF.
E) thymosin.

Accepted Answer

GM-CSF (granulocyte-macrophage colony-stimulating factor) stimulates the production and differentiation of granulocytes and monocytes from hematopoietic cell precursors. M-CSF (macrophage colony-stimulating factor) specifically stimulates the production of monocytes and macrophages, while G-CSF (granulocyte colony-stimulating factor) specifically stimulates the production of neutrophils (a type of granulocyte). Multi-CSF and thymosin are not specifically related to the production of granulocytes and monocytes.
