A “three-in-one” injectable hydrogel platform with osteogenesis, angiogenesis and antibacterial for guiding bone regeneration

Bone regeneration is a complex process consisting of three major parts, osteogenesis, angiogenesis, and antibacterial. The absence of any parts will hinder the regeneration process. For now, there are still limited researches on preparing a general platform for properly combining these three parts. Here, we proposed a strategy by using injectable 4-arm-polyethylene glycol-thiol (4-arm-PEG-SH) hydrogel incorporated with liposomes-calcium...
