How Does TB-500 Work in Published Research?

TB-500 is a synthetic fragment of Thymosin β-4 (Tβ4), a naturally occurring actin-binding protein abundant in human platelets and wound fluid. Its core documented mechanism is G-actin sequestration — binding to and regulating the actin monomers that cells use to reorganize their internal cytoskeleton, a process essential for cell migration toward an injury site.

Published research building on this mechanism documents TB-500 promoting migration and proliferation specifically in endothelial cells, fibroblasts, and keratinocytes — the cell types most directly involved in wound closure and tissue remodeling — alongside angiogenesis (new blood-vessel formation), reduction of post-injury inflammatory cytokine signaling, and stem-cell recruitment to damaged tissue in animal models.
