BPC-157: FAK–paxillin and angiogenic signaling in preclinical models
October 24, 2026 · 1 min read · Models: Rat, Cell culture
BPC-157 is a 15-amino-acid sequence derived from a protein found in gastric juice. Cell-culture studies link it to FAK–paxillin signaling in fibroblasts and to VEGFR2 and nitric-oxide signaling in endothelial cells; most other published work uses rodent models.

Background
“Body protection compound” 157 is a synthetic pentadecapeptide (GEPPPGKPADDAGLV) corresponding to a fragment of a gastric protein. Unlike many peptides, it is reported to be stable in gastric juice. That stability is why early work focused on gastrointestinal injury models in rats.
Selected findings
In tendon fibroblast cultures, investigators reported higher cell survival under oxidative stress and increased cell spreading and migration, which they linked to activation of the FAK–paxillin pathway (Chang et al., Journal of Applied Physiology, 2011). Rat Achilles tendon and medial collateral ligament transection models have been used to compare biomechanical and histological endpoints with those of control animals.
Other work reports increased VEGFR2 expression and nitric-oxide-related signaling in endothelial models, consistent with a pro-angiogenic profile. Gastrointestinal studies in rats measured lesion size in several chemically induced injury models.
How strong is the evidence?
The literature is large but concentrated: most papers come from a single research group in Zagreb. Independent replication, blinded outcome assessment and systematic concentration–response studies are limited. Researchers designing new studies should interpret existing effect sizes cautiously and build in appropriate controls.
