Discovery and initial characterization
Researchers at the University of Zagreb identified BPC-157 as a stable fragment of a larger protein found in human gastric juice. Early studies by Sikiric et al. established the compound's stability in acidic environments and began documenting its effects in gastrointestinal injury models.

Nitric oxide system interactions documented
Research teams explored BPC-157's relationship with the nitric oxide (NO) system, including interactions with NO synthase pathways. These studies positioned BPC-157 within a broader signaling framework involving vascular function and tissue remodeling.
Curr Pharm Des
Angiogenesis and pathway signaling research
Several publications examined BPC-157's effects on angiogenesis-related pathways, including VEGF expression and FAK-paxillin signaling. Researchers began mapping the compound's influence on cell migration and vascular formation in preclinical models.
Systematic review of 36 studies
Vasireddi et al. published a systematic review in the Orthopaedic Journal of Sports Medicine analyzing 36 studies from 1993 to 2024. The review documented BPC-157's effects on growth hormone receptor expression and multiple pathways involved in cell growth and angiogenesis across preclinical models.

Why This Research Matters
The research trajectory of BPC-157 shows a clear progression from basic gastrointestinal studies to a broader understanding of tissue repair mechanisms. Over three decades, published research has expanded from simple cytoprotection models to complex pathway analyses involving growth factor receptors, angiogenesis, and nitric oxide signaling. The 2025 systematic review represents an important milestone — consolidating findings from dozens of studies into a structured framework that informs future preclinical research directions.
