BACKGROUND The Transforming Growth Factors (TGFs) are multifunctional peptides that regulate growth and differentiation in a variety of cells. Recent data suggest that individual TGF-β isoforms (TGF-β 1, -β 2 and _β 3) have overlapping, yet distinct biological actions and target cell specificities, both in developing and adult tissues. TGF-β3 is a new isoform that is presumed to play an important role in wound repair and scarring. TGF-β 3 is also thought to be involved in osteoblast proliferation, chemotaxis, and collagen synthesis.
Recombinant human TGF-β 3 is a non-glycosylated, disulfide-linked homodimer. Each monomer is 112 amino acids, having a total molecular mass of 25.5 kDa.
