Injectable Mussel‐Inspired highly adhesive hydrogel with exosomes for endogenous cell recruitment and cartilage defect regeneration

In the early stage of osteoarthritis (OA), cartilage degradation in the surface region leads to superficial cartilage defect. However, enhancing the regeneration of cartilage defect remains a great challenge for existing hydrogel technology because of the weak adhesion to wet tissue. In the present...
