Injectable Conductive Micro-Cryogel as a Muscle Stem Cell Carrier Improves Myogenic Proliferation, Differentiation and In Situ Skeletal Muscle Regeneration

Volumetric muscle loss (VML) results in the impediment of skeletal muscle function, and there were still challenges in cell delivery approach with the minimally invasive operation to repair muscle defects. To deliver cells to the VML defects site efficiently, the injectable conductive porous nanocomposite microcryogels based on gelatin and reduced graphene oxide were designed and prepared.
