The Claim

BPC 157 at concentrations up to 2 μg/ml for 24 hours does not induce proliferation of rat tendon fibroblasts in vitro, as evidenced by no significant change in MTT assay results or PCNA protein expression.

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

Description
1 study reviewed
In plain English

Exposing rat tendon cells to BPC 157 at concentrations up to 2 μg/ml for 24 hours does not increase cell growth, based on measurements of metabolic activity and a protein marker of cell division.

See the scientific wording

BPC 157 does not directly stimulate proliferation of rat tendon fibroblasts in vitro, as shown by unchanged MTT assay results and PCNA protein expression after 24 hours of exposure at concentrations up to 2 μg/ml.

Why this might work

BPC 157 activates a signaling pathway that makes tendon cells move faster and survive stress, but it does not make them multiply. The cells use this increased movement and protection to repair damaged tissue, even though their total number does not increase.

What the research says

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

    The study found that BPC 157 doesn’t make rat tendon cells multiply faster in a dish, even though it helps them move better and survive stress — so its healing power comes from helping cells move and stay alive, not from making more of them.
