3D-Printed hydroxysafflor yellow A/hydrogel porous scaffolds for bone regeneration.
The integration of angiogenesis with osteogenesis is crucial for the success of scaffolds in treating bone defects. Here, we present a strategy to address this challenge by engineering a 3D-printed porous scaffold that delivers hydroxysafflor yellow A (HSYA), a pro-angiogenic and osteogenic compound from traditional Ch...
