Research Notes
TB-500 is a synthetic peptide that corresponds to the active region of Thymosin Beta-4 (Tβ4), a naturally occurring 44-amino-acid peptide present in nearly all human cells.
Research interest
TB-500 has been investigated in preclinical models for:
- Actin polymerization and cytoskeletal dynamics
- Endothelial cell migration in wound models
- Cardiac and muscle repair signaling
- Angiogenic activity in ischemia models
