About Thymosin Beta-4
- What it is
- Thymosin beta-4 is a naturally occurring 43 amino acid protein that binds and sequesters actin, influencing cell migration, tissue repair, blood vessel formation, and inflammation. Laboratory and animal studies describe roles in wound healing and tissue regeneration, and a synthetic ophthalmic formulation has been evaluated for dry eye and neurotrophic keratopathy. It is the full-length protein, distinct from the TB-500 fragment, and it is not approved.
- How it works
- It binds and sequesters actin to regulate the cytoskeleton, supporting cell migration, tissue repair, and blood vessel growth.
