Abstract

The effect of granulocyte macrophage-colony stimulating factor (GM-CSF), a well-characterized hemopoietic regulator, on protein synthesis in murine bone marrow neutrophils is described. Bone marrow neutrophils in excess of 95% purity were obtained by fluorescence-activated cell sorting. While GM-CSF did not appear to slow the rate of dying of peritoneal exudate neutorphils or thymus cells, the viability of bone marrow neutrophils after 17 hr was enhanced (40%) by GM-CSF. GM-CFS had no effect on total 35S-methionine incorporation by thymocytes or peritoneal exudate neutrophils over a 17-hr incubation period; however, bone marrow neutrophils showed increased incorporation (approximately 10%) a..
