colony-stimulating factors
Definition: a group of glycoprotein growth factors regulating differentiation of myeloid cells. These substances act in either paracrine or autocrine fashion on marrow cells; appear to act synergistically in complex and poorly understood ways; each seems to have the ability to exert action on several lines of progenitor cells, and to influence end cell function.
