TB-500 (Thymosin Beta-4 Fragment 17-23) is a synthetic peptide corresponding to the active actin-binding region of thymosin beta-4, a naturally occurring 43-amino acid protein involved in cell migration and tissue repair. Research investigations have focused on its role as the principal actin-sequestering molecule, regulating cytoskeletal dynamics critical to wound healing and regeneration.
In preclinical models, TB-500 has been studied for accelerating the healing of muscle fibers, tendons, and ligaments through enhanced cell migration and differentiation. Investigations have also examined its promotion of angiogenesis — the formation of new blood vessels — and its anti-inflammatory properties in both acute and chronic injury scenarios. Additional research has explored its effects on connective tissue repair, including reduced scar formation and improved biomechanical properties of healing tissues.
