Granulocyte-Colony Stimulating Factor (G-CSF)

Granulocyte-Colony Stimulating Factor (G-CSF) is a naturally occurring protein in your body that stimulates the production of white blood cells called granulocytes in the bone marrow. These cells are crucial for fighting infections. G-CSF is also used as a medication to help boost white blood cell counts in patients undergoing treatments like chemotherapy, which can lower immunity. By encouraging the production and release of these immune cells, G-CSF helps reduce the risk of infections and supports recovery of the immune system after medical treatments.
