Literature
Research context
TB-500 corresponds to the LKKTETQ actin-binding motif of thymosin beta-4. Preclinical papers describe G-actin sequestration, cell migration in scratch-wound assays, and endothelial tube formation in vitro. It is frequently studied alongside BPC-157 as a comparator in tissue-repair models. Published data is animal and in-vitro only.
Documented research areas
- G-actin sequestration and cytoskeletal dynamics
- Cell migration in scratch-wound assays
- Endothelial tube formation in vitro
