Preparation of 3D Decellularized Matrices from Fetal Mouse Skeletal Muscle for Cell Culture

Overview

This study presents a novel decellularization protocol for fetal mouse skeletal muscle, enabling the creation of matrices that support C2C12 myoblast colonization, proliferation, and differentiation. This in vitro model serves as a valuable tool for investigating skeletal muscle diseases, particularly those that develop in utero.
