Stem Cell Factor (SCF) is a protein that plays a crucial role in the development and function of blood cells. It is produced by various cells in the body, including fibroblasts and endothelial cells, and interacts with c-KIT, a receptor found on the surface of stem cells. This interaction is essential for the survival, proliferation, and differentiation of hematopoietic stem cells. In addition to its role in blood cell formation, SCF is involved in other biological processes, such as melanocyte development and immune system regulation. Its importance in these processes makes it a significant focus of research in regenerative medicine and cancer therapy.
