4. Description:

Stem Cell Factor (SCF) is a potent hematopoietic growth factor required in regulating both embryonic and adult hematopoiesis.SCF protein promotes the survival, differentiation and mobilization of multiple cell types including myeloid, erythroid, megakaryocytic, lymphoid, germ cell and melanocyte progenitors.SCF is primary growth and activation factor for mast cells and eosinophils. And SCF assists in the recovery of cardiac function following myocardial infarction by increasing the number of cardiomyocytes and vascular channels. Stem Cell Factor (SCF) is an important cytokine for ex vivo clinical application. Along with other cytokines, SCF is used in the culture and expansion of hematopoietic stem cells(HSCs) as well as for proliferation and differentiation of both myeloid and erythroid progenitor cells. SCF also can be used in cosmetics to prevent wrinkles formation by creating new epidermal cells, hydrate dry skin and maintain optimal moisture level.
