Thymosin Beta-4
Naturally occurring actin-binding peptide
Thymosin Beta-4 (Tβ4) is a 43-residue actin-binding peptide expressed in many human tissues. Published research spans in vitro cell-biology assays, rodent models, human-organoid work, and a small number of early-phase clinical studies (e.g., in ophthalmology and cardiovascular research).
