Scientific reports

In a rat model of hind-limb ischemia-reperfusion injury, BPC-157 administration reduced oxidative-stress markers (MDA, TOS) and apoptosis-related gene expression (p53, Bax, Caspase-3) while restoring antioxidant capacity (SOD, TAS) and Bcl-2 expression; immunohistochemistry showed reduced Caspase-3 and IL-6 reactivity alongside partially restored VEGF expression in skeletal muscle tissue, consistent with oxidative-stress and angiogenesis pathway research.

In ex vivo human internal mammary artery rings obtained during coronary bypass surgery, BPC-157 produced concentration-dependent vasorelaxation that was significantly greater in endothelium-intact tissue and was attenuated by the nitric oxide synthase inhibitor L-NAME, indicating an endothelium-dependent nitric oxide signaling mechanism underlying vascular tone effects in human arterial tissue.

Using chick chorioallantoic membrane and endothelial tube-formation assays alongside a rat hind-limb ischemia model, this study found BPC-157 increased vessel density and blood-flow recovery, upregulated VEGFR2 expression and internalization in vascular endothelial cells, and activated the VEGFR2-Akt-eNOS signaling pathway, mechanistically linking the peptide to angiogenesis pathway research.

In cultured rat Achilles tendon fibroblasts, BPC-157 upregulated growth hormone receptor expression at the mRNA and protein level and potentiated growth-hormone-driven fibroblast proliferation via Janus kinase 2 signaling, identifying a growth hormone receptor pathway implicated in tendon fibroblast research models.

In rat Achilles tendon explant and fibroblast cultures, BPC-157 accelerated tendon outgrowth, increased fibroblast survival under oxidative stress, and promoted fibroblast migration and spreading via activation of the FAK-paxillin signaling pathway, characterizing a cell-migration mechanism relevant to tendon repair research models.
