What was studied?
Tendon fibroblasts isolated from male rats were assessed with gene-expression assays and protein measurements. Investigators then examined the response of pre-exposed cells to growth hormone, including proliferation-related markers and JAK2 signaling.
What did the researchers report?
BPC-157 increased growth-hormone receptor expression under the tested conditions. Subsequent growth-hormone exposure produced changes in proliferation-related measurements and downstream signaling in those cells.
What are the limits?
Receptor expression in cultured tendon cells does not show that BPC-157 raises circulating growth hormone or heals human injuries. The combined laboratory conditions are not a recommendation to combine substances. Cell assays, species and the precise experimental materials matter when interpreting this proposed mechanism.
