The treatment of critical-size bone defects with irregular shapes remains a major challenge in the field orthopedics. Bone implants adaptability to complex morphological defects, bone-adhesive properties, and potent osteogenic capacity are necessary. Here, shape-adaptive, highly bone-adhesive, ultrasound-powered injectable nanocomposite hydrogel is developed via dynamic covalent crosslinking amine-modified piezoelectric nanoparticles biopolymer networks for electrically accelerated healing. Depending on inorganic-organic interaction between amino-modified bio-adhesive network, adhesive strength prepared exhibited an approximately 3-fold increase. In response ultrasound radiation, could generate controllable electrical output (-41.16 61.82 mV) enhance effect vitro vivo significantly. Rat calvarial defect repair validates addition, bioinformatics analysis reveals that ultrasound-responsive enhanced differentiation mesenchymal stem cells by increasing calcium ion influx up-regulating PI3K/AKT MEK/ERK signaling pathways.

Abstract The osteoimmune microenvironment induced by implants plays a significant role in bone regeneration. It is essential to efficiently and timely switch the macrophage phenotype from M1 M2 for optimal healing. This study examined impact of calcium phosphate (CaP) coating on physiochemical properties highly ordered polycaprolactone (PCL) scaffolds fabricated using melt electrowritten (MEW). Additionally, it investigated influence these polarization their immunomodulation osteogenesis. results revealed that CaP coated PCL scaffold exhibited rougher surface topography higher hydrophilicity comparison without coating. Besides, morphology release Ca 2+ were crucial regulating transition macrophages phenotypes. They might activate PI3K/AKT cAMP-PKA pathways, respectively, facilitate polarization. In addition, could not only enhance osteogenic differentiation marrow-derived mesenchymal stem cells (BMSCs) vitro but also promote regeneration vivo.
