Actin Sequestration & Satellite Cell Activation

TB-500 is a synthetic analogue of the active Ac-LKKTETQ region of Thymosin Beta-4 (Tβ4), a 43-amino-acid peptide present in virtually all nucleated cells. Its primary mechanism is G-actin sequestration via the Ac-LKKTETQ motif — this promotes cell migration, angiogenesis, and tissue repair by controlling actin polymerization dynamics. TB-500 activates satellite cells (muscle stem cells), upregulates metalloproteinases for ECM remodeling, and reduces pro-inflammatory cytokines including TNF-α and IL-1β. Its systemic cell migration properties make it complementary to BPC-157's local angiogenic mechanism — the two are the most studied peptide repair combination in published literature. Molecular weight: 2174.5 Da.
