Myoblast or myoblast-like cell culture method for in vitro myofiber formation

摘要

An object of the present invention is to differentiate myoblasts and efficiently prepare contractible muscle fibers. Prior to differentiation induction, myoblasts are efficiently differentiated into muscle fibers by exposure to endoplasmic reticulum-specific endoplasmic reticulum (ER) stress followed by induction of differentiation.
