MGF (Mechano Growth Factor)

Research-Grade IGF-1 Isoform
Tagline: Muscle Growth & Repair Research

Product Description

MGF (Mechano Growth Factor) is a splice variant of IGF-1 (Insulin-Like Growth Factor-1) expressed locally in skeletal muscle following mechanical overload or injury. MGF is a potent stimulator of satellite cell activation and muscle regeneration.

Researchers use MGF in studies of muscle hypertrophy, injury repair, regenerative medicine, and age-related muscle decline. Its short half-life provides insight into localized, transient IGF-1 signaling events.

For Laboratory and Scientific Research Use Only. Not for Human Consumption.

Why Researchers Choose MGF

  • Endogenous IGF-1 Isoform: Allows modeling of natural muscle repair processes.

  • Muscle-Specific Expression: Studied as a locally acting growth factor for hypertrophy.

  • Satellite Cell Activation: Key regulator of myoblast proliferation and differentiation.

  • Short Half-Life: Enables research on transient anabolic signaling.

  • Batch Verified: ≥98% purity, HPLC and MS-tested for consistency.

Important Note

For laboratory and scientific research only. Not for human consumption, therapeutic, or diagnostic use.

Research Applications

Muscle Hypertrophy Studies

MGF expression is upregulated following mechanical overload, promoting local muscle growth and hypertrophy [1].

Injury Repair Models

Shown to stimulate satellite cell proliferation and accelerate repair after muscle injury [2].

Age-Related Muscle Loss Research

MGF levels decline with age; supplementation is used in models to investigate sarcopenia reversal [3].

Regenerative Medicine Applications

Explored for its potential to enhance muscle regeneration in degenerative diseases [4].

Mechanism of Action (How MGF Works)

  • Local IGF-1 Splice Variant: Expressed rapidly in muscle after mechanical load, acting as an autocrine/paracrine growth signal [Goldspink 2005].

  • Satellite Cell Recruitment: Stimulates satellite cell proliferation and differentiation, aiding muscle regeneration [Hill 2003].

  • Transient Anabolic Signaling: Short half-life allows for rapid, localized muscle adaptation without systemic effects [Owino 2001].

  • Synergy with IGF-1Ea: Works with other IGF-1 isoforms to complete the hypertrophic response [McKay 2008].
