Electrosprayed microspheres for bone regeneration are conventionally restricted by the lack of osteogenic modulation for both encapsulated stem cells and surrounding cells at the defect site. Here, sodium alginate microspheres encapsulating L‐arginine doped hydroxyapatite nanoparticles (Arg/HA NPs) and bone mesenchymal stem cells (BMSCs) as regeneration‐enhancer‐element reservoirs (Arg/HA‐SA@BMSC)...
Bone Tissue Repair
In article number 2200314, Xin Zhao and co‐workers electrospray microspheres encapsulating stem cells and natural tissue metabolites as regeneration‐enhancer‐element reservoirs to power the inside/outside microsphere cell–cell/cell–material communication for accelerated vascularized bone tissue repair.
Current periosteal grafts have limitations related to low mechanical strength, tissue adhesiveness, and poor osteogenesis and angiogenesis potential. Here, a periosteum mimicking bone aid (PMBA) with similar structure and function to natural periosteum is developed by electrospinning photocrosslinkable methacrylated gelatin (GelMA), l‐arginine‐based unsaturated poly(ester amide) (Arg‐UPEA), and methacrylated...
