This dual action (proliferate but dont yet differentiate) is mechanistically distinct from mature IGF-1, which primarily drives differentiation, and explains why MGF and IGF-1Ea have sequential, complementary roles in the muscle regeneration programme: Acute phase (024 hours post-injury): MGF/IGF-1Ec mRNA peaks locally in damaged muscle confirmed at T24 in human muscle following eccentric exercise activating satellite cells to exit quiescence and enter the cell cycle Proliferative phase (2472 hours): Satellite cells proliferate, fuelled by MGF signalling, while differentiation is suppressed Differentiation phase (72120+ hours): IGF-1Ea mRNA rises as MGF declines shifting the programme toward myoblast differentiation, myotube fusion, and myofibre maturation PEG-MGF allows researchers to deliver the MGF signal at controlled intervals across this entire time course without the pharmacokinetic limitations of native MGF

A long time ago, pernicious anemia was fatal (pernicious means "deadly")
This is one of the first controlled studies validating copper peptide microneedling for hair specifically
That anti-inflammatory component is particularly relevant for our patient population in Doral, where Fitzpatrick III-V skin types require a treatment approach that produces repair without triggering the melanocyte response
