Bionic Biphasic Composite Scaffolds with Osteochondrogenic Factors for Regeneration of Full-Thickness Osteochondral Defects

Researchers constructed a bionic biphasic composite scaffold with on-demand osteochondrogenic factors. Kartogenin and extractive MSCs were introduced into a mPEG-block-poly(L-valine) thermogel set as the upper layer to accelerate cartilage repair.
