Biomimetic 3D aligned conductive tubular cryogel scaffolds with mechanical anisotropy for 3D cell alignment, differentiation and in vivo skeletal muscle regeneration

Developing 3D conductive aligned cryogels has great potential for skeletal muscle trauma treatment because they can mimic anisotropic structure, conductivity, and recoverable cyclic compression of the microenvironment of native skeletal muscle. In this work, a series of cryogels possessing 3D aligned morphology, conductivity, and excellent anisotropic mechanical compression property based on gelatin (GT) and polydopamine coated carbon nanotubes...
