TB-500

TB-500 is a synthetic peptide fragment derived from the naturally occurring Thymosin Beta-4 (Tβ4) protein, a 43-amino-acid peptide found in almost all mammalian cells. In pre-clinical and in-vitro studies, TB-500 has been widely examined for its ability to enhance cellular migration, promote angiogenesis, modulate inflammation, and accelerate tissue repair.

TB-500’s biological activity is primarily attributed to its regulation of G-actin polymerization, a process critical to cell movement, structure, and differentiation. Because of this, TB-500 is frequently used in research focused on wound healing, muscle and tendon recovery, angiogenic signaling, and cytoskeletal organization.

  • Used in studies investigating cellular migration, tissue remodeling, and cytoskeletal reorganization.
  • Provides a model for analyzing cellular response to injury and structural regeneration.

Angiogenesis and Vascular Growth Research

  • Demonstrated in pre-clinical models to influence endothelial cell migration, capillary formation, and vascular stability.
  • Enables exploration of angiogenic signaling, oxygenation pathways, and vascular remodeling mechanisms.
  • Often paired with BPC-157 or AICAR in studies related to vascular regeneration and tissue perfusion.

Muscle and Connective Tissue Regeneration Studies

  • TB-500 has been shown to enhance myoblast differentiation and fibroblast activity, supporting research on skeletal muscle recovery and connective tissue repair.
  • Commonly used in pre-clinical models to study myocardial repair, tendon regeneration, and muscle hypertrophy.
  • Provides insight into peptide-mediated anabolic signaling in soft tissue biology.

Anti-Inflammatory and Immune Modulation Research

  • Known to affect cytokine balance, helping researchers understand immune response regulation during tissue recovery.
  • Used in studies focusing on NF-κB inhibition, macrophage polarization, and anti-inflammatory peptide pathways.
  • Facilitates analysis of immune-mediated wound healing and cell migration under inflammatory stress.

Wound Healing and Tissue Remodeling Studies

  • Provides a valuable model for epithelial cell migration, collagen deposition, and extracellular matrix (ECM) realignment.
  • Studied for its potential to support keratinocyte regeneration and angiogenic tissue repair in pre-clinical wound-healing assays.
  • Offers researchers insight into biochemical and cellular cascades responsible for post-injury tissue recovery.

Cardiovascular and Ischemic Research

  • Utilized in laboratory models to study myocardial cell regeneration and tissue response under hypoxic conditions.
  • Supports research into cardiac myocyte migration, angiogenic remodeling, and microvascular reoxygenation following ischemic insult.
