Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In mouse osteoblast cells, the abundance of the Eb splice product (mechano-growth factor) was unchanged during osteoblastic differentiation.

    In plain wordsIn mouse bone cells, natural MGF levels stayed the same while the cells matured.

    Summary
    We identified two splice products, exon 4+6 (Ea) and exon 4+5+6 (Eb, mechano-growth factor) and found that their abundance was unchanged during osteoblastic differentiation.

    This result measures the body's own MGF / PEG-MGF. Nobody was given the peptide. It is not evidence about taking it.
