G-CSF is a cytokine that plays a vital role in the production and differentiation of granulocytes, particularly neutrophils. It is naturally produced by the body, but recombinant forms are often administered to patients to mitigate neutropenia, a common side effect of chemotherapy and radiation therapy. Through binding to specific receptors on hematopoietic stem cells, G-CSF enhances the proliferation and differentiation of neutrophil precursors.
