Non disponible en dehors du Royaume-Uni et de l'Irlande

Analysis Note

The biological activity is measured by its ability to inhibit the IL-4-dependent proliferation of mouse HT-2 cells.

Application

Transforming Growth Factor-β3 human has been used to study the role of TGF-β3 in healing tendon-to-bone insertion and in chondrogenic differentiation.

Biochem/physiol Actions

TGF-β (transforming growth factor-β3) isoforms are significantly involved in inducing inflammatory responses. It is associated with vascular diseases, wound healing and ameliorating effect in venous leg ulcer. TGF-β3 has an antagonistic effect on TGF-β1 and reduces the degree of collagen type I deposition and fibroblast differentiation. As a result TGF-β3 might lead to ulcer chronicity due to hindered myofibroblasts formation. TGF-β is a key player in tumor formation and progression. Increased TGF-β3 expression is observed in cancer and adipose tissue fibrosis. TGF-β3 is crucial in tissue regeneration and scarless tissue repair.

TGF-β3 is less prevalent in natural expression than either TGF-β1 or TGF-β2, but it is the most abundant mRNA expressed in chick embryos. It is also expressed in human umbilical cord, in a variety of mesenchymal cells of human and rodent origin, and in several human carcinoma cells.

General description

The TGFβ3 (transforming Growth Factor-β3) gene is mapped to human chromosome 14q24.3.

Physical form

Lyophilized from a 0.2 µm filtered solution in 35% acetonitrile and 0.1% trifluoroacetic acid containing 50 µg bovine serum albumin per 1 µg of cytokine.
