What is TB-500?
TB-500 corresponds to the active actin-binding fragment of Thymosin Beta-4. Research focuses on cell migration, angiogenesis and remodelling of the actin cytoskeleton.
Mechanism of action
Promotes cell migration, angiogenesis and actin remodeling.
Primary research areas
Soft tissue repair, fibroblast migration studies.
Research notes
- Actin-sequestering action underlies its role in migration research.
TB-500: expanded research context
TB-500 is a synthetic version of the active 17-amino-acid fragment (residues 17–23) of thymosin β4. Thymosin β4 is a G-actin sequestering peptide implicated in cell migration, angiogenesis, and dermal, corneal and cardiac wound repair. TB-500 is used as a research reference for regenerative-signalling studies in soft tissue and vascular models.
Reported half-life is short, but downstream effects on actin cytoskeletal reorganisation persist beyond plasma exposure in in-vitro assays. Regulatory status mirrors BPC-157: TB-500 is prohibited by WADA (S2 peptide hormones and mimetics) and is not a licensed medicine.
Literature for orientation
A short reading list of papers that mention TB-500. These are listed so you can find the primary sources yourself — they are not claims about our stock. Look up the full text on PubMed or via the journal DOI.
Thymosin β4 in dermal wound repair
Annals of the New York Academy of Sciences · 2007
Landmark synthesis of thymosin β4 preclinical wound-healing data across dermal, corneal and cardiac models.
Thymosin β4 in myocardial infarction (mouse)
Nature · 2004 (Bock-Marquette et al.)
Systemic thymosin β4 reduced infarct size and improved cardiac function post-MI in a murine model.
Angiogenesis and endothelial migration in vitro
Journal of Cell Science · 2009
Thymosin β4 promoted endothelial cell migration, tubulogenesis and VEGF-driven vascular sprouting.
WADA Prohibited List — S2 peptide hormones and mimetics
World Anti-Doping Agency · 2024
TB-500 and thymosin β4 are prohibited in and out of competition under WADA S2.
