PEG-MGF
Pegylated Mechano Growth Factor — Muscle Repair Signaling
01
Overview
PEG-MGF (Pegylated Mechano Growth Factor) is a modified form of IGF-1 splice variant that is produced locally in muscles following mechanical damage or exercise. Pegylation extends its half-life from minutes to days. Research indicates it stimulates myosatellite cell activation and proliferation, supporting muscle repair and hypertrophy independently of systemic IGF-1.
02
Mechanism of Action
MGF activates a unique receptor distinct from the canonical IGF-1R, stimulating Akt phosphorylation and protein synthesis via mTOR. The E-domain peptide of MGF specifically activates satellite cells, driving their entry into the cell cycle and subsequent differentiation into mature muscle fibers.
03
Research Highlights
Muscle injury research demonstrates accelerated satellite cell activation compared to systemic IGF-1
Cardiac research shows protective effects against heart failure in murine models
Comparative studies confirm superior local muscle effects versus systemic IGF-1Ea administration
04
