BPC-157: Mechanism, Research & Repair Pathways
BPC-157 (Body Protective Compound-157) is a synthetic 15-amino-acid peptide fragment derived from a protein isolated in human gastric juice. It has become one of the most heavily studied research peptides in preclinical wound-healing and gastrointestinal science.
Mechanism of action
BPC-157 is thought to act through upregulation of VEGFR2, endothelial nitric oxide synthase (eNOS) and the growth-hormone receptor axis. Preclinical models show increased microvascular sprouting, restored blood-flow in ischemic tissue, and normalization of gastrointestinal integrity via NO-dependent pathways.
Research benefits
- Accelerated tendon and ligament repair in rodent models
- Preservation of gastric and intestinal mucosal integrity
- Upregulation of angiogenic markers (VEGF, eNOS)
- Attenuation of inflammatory cytokines in injury models
