The Claim

BPC 157 at concentrations of 0.5–2 μg/ml increases phosphorylation of FAK and paxillin in rat tendon fibroblasts without altering total protein levels, indicating activation of the FAK-paxillin signaling pathway.

Source: The promoting effect of pentadecapeptide BPC 157 on tendon healing involves tendon outgrowth, cell survival, and cell migration.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

BPC 157 at concentrations of 0.5–2 μg/ml increases phosphorylation of FAK and paxillin proteins in rat tendon fibroblasts without changing their total amount, which indicates activation of the FAK-paxillin signaling pathway.

See the scientific wording

BPC 157 at concentrations of 0.5–2 μg/ml dose-dependently increases phosphorylation of FAK and paxillin in rat tendon fibroblasts without altering total protein levels, indicating activation of the FAK-paxillin signaling pathway as a potential mechanism for enhanced cell migration and spreading.

Why this might work

BPC 157 binds to a receptor on the surface of tendon cells, triggering a chain reaction that turns on FAK and paxillin proteins. These activated proteins reorganize the cell's internal skeleton, allowing the cells to spread out and move faster to repair damaged tendon tissue.

  1. Study: The promoting effect of pentadecapeptide BPC 157 on tendon healing involves tendon outgrowth, cell survival, and cell migration.

    BPC 157 helps rat tendon cells move and spread better by turning on a specific internal signal (FAK-paxillin) without making more of those proteins — just making them more active.
