Mechanism context
BPC-157 is studied for its reported interaction with nitric-oxide and growth-factor signalling (VEGFR2, FAK-paxillin) in repair models. TB-500 research centres on the actin-binding LKKTET motif and cell-migration behaviour. Because the proposed pathways differ, the two are often studied together in combined recovery models.
