Thymosin Beta 4 (TB-500) is the naturally derived thymic peptide corresponding to the synthetic TB-500 research compound. As one of the most abundant peptides in mammalian cells, it plays critical roles in actin sequestration, cytoskeletal organization, and cellular migration. Preclinical research has extensively studied its regenerative, anti-inflammatory, angiogenic, and cardioprotective properties in healing models involving cardiac tissue, neurological injury, musculoskeletal repair, and dermal wound closure.
