After treatment, cells were immediately analyzed for apoptosis and the cell cycle using a BD FACSCelesta Cell Analyzer with an Annexin V-FITC/PI Apoptosis Detection Kit and PI/RNase Staining Buffer (BD Biosciences, Franklin Lakes, NJ, USA), respectively, according to the manufacturers instructions
FAK-paxillin pathway: Cell culture work suggests BPC-157 activates focal adhesion kinase (FAK) and paxillin, proteins involved in cell migration important for wound closure
In addition, the peptide supports glycosaminoglycan synthesis, including hyaluronic acid, which improves hydration and barrier function
Composed of 15 amino acids, this pentadecapeptide has been shown in research to stimulate angiogenesis, collagen formation, and tissue remodeling.- It may interact with nitric oxide pathways, growth factor expression, and inflammatory cascades to support endothelial function and cellular recovery.- Suggested mechanisms include upregulation of VEGF, engagement with FAK-paxillin signaling, and protective effects under oxidative stress conditions
Most patients start at 300 mcg/day and titrate toward 500 mcg/day
