TB-500 Published Research

TB-500 is a synthetic analog of Thymosin Beta-4 (Tβ4), a 43-amino acid peptide naturally occurring in most mammalian tissues. Thymosin Beta-4 was first isolated from thymus tissue in the 1960s and has been the subject of substantial research regarding its role in cell migration, differentiation, and tissue repair processes.

Cell Migration and Actin Regulation

Thymosin Beta-4 is one of the primary intracellular G-actin sequestering peptides. Published research has demonstrated its critical role in actin polymerization dynamics, which underlies cell motility and migration. Studies in cell culture models showed that Tβ4 promotes endothelial cell migration, a key process studied in angiogenesis research.

Cardiac Research

Several research groups have investigated Thymosin Beta-4 in cardiac models. Studies published in Nature examined Tβ4 in myocardial injury models in mice, investigating markers of cardiac function and tissue remodeling. Research has also examined Tβ4 in the context of epicardial progenitor cell activation and coronary vasculogenesis in developmental biology models.

Dermal and Hair Follicle Research

Published research has examined Thymosin Beta-4 in dermal wound models and hair follicle biology. Studies in murine models investigated the role of Tβ4 in keratinocyte migration and hair follicle stem cell activation. Research published in PNAS characterized Tβ4-mediated signaling in hair growth cycle regulation.
