Mechano growth factor
Mechano-growth factor can refer to an IGF-I splice form or its proposed C-terminal E-peptide. Synthetic MGF peptide, stabilized analogues, and full-length IGF-I are different materials.
At a glance
- Evidence stage
- Preclinical
- Regulatory status
- Research reference; the cited studies do not establish a human muscle-repair indication or an approved MGF product.
- Research context
- Mechano-growth factor can refer to an IGF-I splice form or its proposed C-terminal E-peptide. Synthetic MGF peptide, stabilized analogues, and full-length IGF-I are different materials.
What this is
- Mechano-growth factor can refer to an IGF-I splice form or its proposed C-terminal E-peptide. Synthetic MGF peptide, stabilized analogues, and full-length IGF-I are different materials.
What this isn't
- A recommendation to use, prepare, combine, or administer a product
- Evidence that a related molecule or a differently formulated product has the same effects
Key terms
Mechano-growth factor can refer to an IGF-I splice form or its proposed C-terminal E-peptide. Synthetic MGF peptide, stabilized analogues, and full-length IGF-I are different materials.
Exercise-associated changes in IGF-I gene splicing motivated the hypothesis that an E-domain peptide independently promotes muscle regeneration. That hypothesis must be separated from the known activity of mature IGF-I. The primary replication study directly tested the synthetic peptide rather than assuming that increased expression of a splice transcript proves a benefit from administering its isolated fragment.
Evidence limits
How to read the evidence
An analytical study developed blood detection methods for MGF and related compounds; it did not demonstrate human therapeutic benefit. Identifying a substance in a test panel, studying human-derived cells, and treating humans are different activities. The exact sequence, modification, and biological preparation must be specified before comparing findings, and contradictory preclinical results should remain visible in any discussion of recovery or performance.
