Specifications

Stem cell factor (SCF) is a type I transmembrane protein and hematopoietic growth factor which acts in synergy with other growth factors, and signals through the receptor tyrosine kinase c-Kit (CD117). The interaction between SCF and c-Kit regulates developmental and functional processes of hematopoietic progenitor cells, mast cells, myelanocytes and germ cells, and plays an important role in follicular development. Studies have also shown that the interaction between SCF and c-Kit is associated with the progression and invasiveness of some tumors, including melanomas.
