Quick answer

What is Mechano growth factor?

Built from index records dated 2026-10-09 to 2026-10-13 Compiled by an automated pipeline, checked by The Peptide Observer editorial desk How this site works

Mechano growth factor is a peptide, grouped on this site under Growth factors and growth hormone-derived compounds, and the 12 research records kept here are 7 from studies in rats or mice and 5 that do not state what kind of study it is.

The literature search returned 222 records. This site keeps 12 of them, which is 5.4 per cent of what came back.

What it is

This site puts it in the Growth factors and growth hormone-derived compounds group.

An IGF-I splice variant whose E-domain peptide is reported in the retrieved records to act on muscle progenitor cells; the 2014 American Journal of Physiology record reports no apparent effect in its model, so the mechanism is contested in the retrieved set.[1, 2]

Stated in the titles of the cited 2011 Mechanisms of Ageing and Development and 2014 American Journal of Physiology papers.

What kind of records

No public chemistry record was found under this name, so the entry describes a preparation, a protein or a mixture rather than one defined molecule.

That sentence is produced by counting, not by reading. What was counted: PubChem returned no compound record for this name, so the subject is a preparation, protein or mixture rather than a defined small molecule; identity fields are unsourced.

What this does not settle
