Transforming growth factor beta (TGF-β) is a potent cell regulatory polypeptide homodimer of 25kD.[1] It is a multifunctional signaling molecule with more than 40 related family members. TGF-β plays a role in a wide array of cellular processes including early embryonic development, cell growth, differentiation, motility, and apoptosis.[2]
