Reported in preclinical, in-vitro literature in the following research areas:

• Actin regulation & cytoskeletal dynamics
• Cell-migration models
• Angiogenesis research
• Tissue-repair signaling

These are areas of laboratory investigation only. No physiological, clinical, or health outcome is claimed or implied for any use of this compound.

TB-500 is derived from the actin-binding region of thymosin β4. In published research, thymosin β4 sequesters G-actin and influences cell-migration and repair-associated signaling; the fragment is used to probe these pathways in vitro.
