The physiological function of a recently cloned splice variant of insulin‐like growth factor‐I (IGF‐I; mechano growth factor (MGF)) was studied using an in vitro cell model. Unlike mature IGF‐I, the distinct E domain of MGF inhibits terminal differentiation whilst increasing myoblast proliferation. Blocking the IGF‐I receptor with a specific antibody indicated that the function of MGF E domain is mediated via a different receptor. The results provide a basis for localized tissue adaptation and… Expand
