Overview
TB-500 is the laboratory designation for the 43–amino-acid peptide segment of thymosin beta-4 (Tβ4) responsible for actin-binding, cell migration, and tissue regeneration. Its unique molecular profile makes it a popular choice among researchers in regenerative medicine and sports-injury models across the USA.
TB-500 Peptide Structure
- Sequence: Ac-Ser-Asp-Lys-Pro-Ala-Ile-Glu-Gln-Gly-Glu-Ser-Ile-Gly-Asp-Lys-Lys-Leu-Lys-Glu-Lys-Lys-Ile-Gly-Glu-Gln-Asp-Lys-Ser-Leu-Asp-Lys-Lys-Gln-Gly-Glu-Lys-Gln-Met-Glu-Asp-Lys-Ser
- Molecular Formula: C212H350N56O78S
- Molecular Weight: 4963 g/mol
- PubChem CID: 123829
Mechanisms of Action
TB-500 promotes cell migration by sequestering G-actin and up-regulating VEGF, IL-8, and keratinocyte growth factor pathways. Additional in-vitro data suggest modulation of osteopontin, up-regulation of angiopoietin-1, and suppression of NF-κB inflammatory signaling—collectively supporting tissue repair and anti-fibrotic outcomes.
Research Areas
- Wound Healing & Angiogenesis – Accelerated re-epithelialization, increased capillary density, and reduced scar formation in rodent and porcine models.[1][2][3]
- Muscle, Tendon & Ligament Repair – Enhanced myoblast differentiation, collagen deposition, and tensile strength in musculoskeletal injury studies.[4][5][6]
- Hair-Follicle & Skin Applications – Promotes dermal papilla proliferation and anagen-phase induction in hair-regrowth research.[7][8][9]
- Cardiac & Organ Protection – Demonstrates cardioprotective effects post-myocardial infarction and mitigates ischemia–reperfusion damage in liver and kidney models.[10][11]
- Anti-Inflammatory & Fibrosis Reduction – Down-regulates pro-inflammatory cytokines while inhibiting fibroblast-to-myofibroblast transition.[12][13]
- Metabolic & Performance Research – Preliminary studies indicate improved angiogenesis-mediated endurance capacity, making TB-500 a target for performance-related investigations.[14]
