Overview
Mechano Growth Factor (MGF) is a peptide derived from the splicing of the IGF-1 gene, specifically triggered by mechanical stress or physical trauma to muscle tissue. While IGF-1 is systemic, MGF acts as a localized repair signal that jumpstarts the regenerative process. It is particularly noted for its ability to stimulate satellite cell activation, which provides the necessary biological "seeds" for new muscle growth and the restoration of damaged fibers.
In the context of physical performance and clinical research, MGF is valued for its potential to reverse age-related muscle wasting and accelerate recovery from intense training. Though human clinical trials are limited compared to other growth factors, it is widely utilized in research settings to explore treatments for muscle-wasting diseases and to enhance physique development by increasing the capacity for muscle cell proliferation.
Mechanism of action
MGF is a splice variant of IGF-1 that responds to mechanical stress by activating muscle stem cell pools and recruiting amino acids to facilitate the regeneration of skeletal muscle tissue.
