What was done
Rats with surgically transected right Achilles tendons received daily intraperitoneal injections of gastric pentadecapeptide BPC 157 (10 µg/kg, 10 ng/kg, or 10 pg/kg) or saline control starting 30 minutes post-surgery until 24 hours before sacrifice. Functional recovery was tracked daily via the Achilles functional index (AFI). Biomechanical properties (failure load, load per area, Young's modulus), histology, and macroscopic defect size were assessed on days 1, 4, 7, 10, and 14. In vitro, cultured tendocyte growth was evaluated with BPC 157 alone and combined with the growth inhibitor 4-hydroxynonenal (HNE) in serum and serum-deprived conditions.
What was found
The abstract reports directional outcomes without exact numerical values or confidence intervals. BPC 157-treated rats showed higher AFI functional scores, increased load of failure, greater Young's modulus of elasticity, and reduced macroscopic tendon defect dimensions compared to saline controls. Microscopically, treated tissues demonstrated higher mononuclear cell counts, fewer granulocytes, and enhanced fibroblast, reticulin, and collagen formation. In vitro, BPC 157 alone did not alter baseline tendocyte growth but reversed HNE-induced growth inhibition under both serum-containing and serum-deprived conditions.
Why it matters
This study provides early preclinical evidence that BPC 157 can enhance structural and functional recovery in transected tendons and protect tendocytes from oxidative growth inhibition.
Limits
The study was performed entirely in rats and cell cultures, precluding direct clinical translation. The abstract omits sample sizes (n), specific numerical values, error metrics, and exact statistical test results.
