Three-dimensional composite aerogel scaffolds based on electrospun poly(lactic acid)/gelatin and silica-strontium oxide short fibers promote bone defect healing

Leveraging the synergistic effects of SiO_2-SrO nanofibers and PG polymers, this study presents a multifunctional scaffold capable of promoting bone regeneration through dual osteogenic and angiogenic stimulation. Our findings highlight the potential of this composite system not only for bone tissue engineering but also for broader biomedical applications.
