Amphiregulin Lysates

Amphiregulin (AR) is an EGF family growth factor that is released as a soluble protein following proteolytic cleavage of its transmembrane precursor. Amphiregulin is expressed by numerous carcinoma cell lines and epithelial cells of the colon, stomach, breast, ovary and kidney. It acts through ErbB family of receptor to stimulate the proliferation of keratinocytes, mammary epithelial cells, fibroblasts, astrocytes and glial cells. Amphiregulin can also inhibit the growth of certain tumor cells.
