TB-500 (Thymosin Beta-4 Fragment) Research Guide: Tissue Repair Science

Introduction to TB-500

TB-500 corresponds to the active actin-binding domain of thymosin beta-4 (Tβ4), an intracellular protein central to actin polymerization. Research indicates this fragment retains much of the full protein’s biological activity.

TB-500 Key Research Mechanisms
Actin Sequestration
Binds G-actin and modulates cytoskeletal dynamics — regulates cell migration, critical to tissue repair.
Pro-Angiogenesis
Studies documented upregulation of VEGF and endothelial cell migration in wound healing and ischemia models.
Anti-Inflammatory
Documented reduction of IL-1β and TNF-α; NF-κB signalling modulation across multiple model systems.

Cardiac Progenitor Activation
Nature (2004): Tβ4 activates dormant epicardial progenitor cells — a significant cardiac repair research finding.
