G-CSF
Granulocyte Colony-Stimulating Factor (G-CSF)
A cytokine that stimulates neutrophil production and mobilizes hematopoietic stem cells. FDA-approved for chemotherapy-induced neutropenia and stem cell mobilization.
Mechanism of Action
G-CSF binds to G-CSFR receptors on neutrophil precursors and hematopoietic stem cells, stimulating proliferation, differentiation, and mobilization from bone marrow.
Health Claims & Evidence
Stimulates neutrophil production
Mobilizes hematopoietic stem cells
Potential cardiac repair via stem cell mobilization
Short-Term Effects
Rapid neutrophil increase, bone pain (from marrow expansion).
Long-Term Effects
Sustained neutrophil recovery with continued use.
Side Effects
Bone pain, splenomegaly, rare splenic rupture.
Contraindications
Use with caution in myeloid malignancies.
