Shipping Room temperature in continental US; may vary elsewhere. Background Transforming growth factor-β (TGF-β) is a glycoprotein that acts as a cytokine. This multifunctional cytokine has a pivotal role in the regulation of many cellular activities, such as proliferation, differentiation, and other functions, and also plays a role in immunity, cancer, heart disease, diabetes, Marfan syndrome, Loeys–Dietz syndrome, Parkinson's disease, and AIDS. Three TGF-β isoforms have been found in mammals: TGF-β1, 2, and 3, which are structurally and functionally similar. Transforming Growth Factor β3 expression increases in fetal wound healing and reduces fibronectin and collagen I and III deposition, and also improves the architecture of the neodermis which is a combination of blood vessels and connective tissue during wound healing[1]. Transforming Growth Factor β3 has been found to have an important role in normal developmental biology including systems such as the heart, lung and breast and to display isoform-specific biology at both the in vivo and in vitro level[2]. |
