[Phagocytosis and oxidative metabolism of granulocytes in mice after stem cell factor (SCF) injection].
Stem Cell Factor (SCF) can stimulate the growth and development of primitive multipotential and unipotential hematopoietic stem cells, either alone or in combination with other cytokines such as Granulocyte-Macrophage Colony Stimulating factor (GM-CSF) and Granulocyte-CSF (G-CSF). It was found that these cytokines can also stimulate the function of granulocytes but there is no information concerning SCF influence on the function of these mature cells. SCF was injected into mice subcutaneously during 5 consecutive days in a dose of 1 microgram/kg/d. An examination of the percentage of phagocytic granulocytes and NBT test was performed. The activity of acid phosphatase (AcP), alkaline phosphatase (AP), peroxidase (MPO) and esterase were determined by cytochemistry methods. On the basis of obtained results we can conclude that SCF evidently increases all tested parameters connected with the metabolism of phagocytosis.
