Injectable Decellularized Wharton’s Jelly Hydrogel Containing CD56+ Umbilical Cord Mesenchymal Stem Cell-Derived Exosomes for Meniscus Tear Healing and Cartilage Protection

Modified decellularized Wharton’s Jelly hydrogel (DWJH) was combined with isolated CD56+Exos from CD56+umbilical cord MSCs to fabricate DWJH/CD56+Exos. The in vitro studies were performed to characterize the DWJ.
