About TB-500
TB-500 is a synthetic peptide fragment of the naturally occurring protein Thymosin Beta-4 (Tβ4). The active region of Tβ4 responsible for actin binding and cellular migration is replicated in TB-500. Preclinical studies have explored its role in promoting angiogenesis, reducing inflammation, and accelerating wound closure. It has been studied in models of cardiac repair, corneal healing, and dermal wound healing.
