Colony-stimulating factor

Colony-stimulating factor: A laboratory-made agent similar to a substance in the body that stimulates the production of blood cells.

Treatment with colony-stimulating factors (CSFs) can help the blood- forming tissue recover from the effects of chemotherapy and radiation therapy.

The CSFs include granulocyte colony-stimulating factors (G-CSF) and granulocyte-macrophage colony-stimulating factors (GM-CSF).
