Biocompatibility and Bone-Repairing Effects: Comparison Between Porous Poly-Lactic-Co-Glycolic Acid and Nano-Hydroxyapatite/Poly(lactic acid) Scaffolds

Copolymer composite scaffolds and bioceramic/polymer composite scaffolds are two representative forms of composite scaffolds used for bone tissue engineering. Studies to compare biocompatibility and bone-repairing effects between these two scaffolds are significant for selecting or improving the scaffold for clinical application. We prepared two porous scaffolds comprising poly-lactic-acid/poly-glycolic-acid (PLGA) and...
