Loading efficiency and in vitro release pattern of quercetin and BMP-2 from hydroxyapatite microbeads. A Loading efficiency of quercetin and BMP-2 is represented. B Release quantity of quercetin from microbeads loaded with both quercetin and BMP-2 (gray line) and quercetin from microbeads loaded with only quercetin (blue line). C BMP-2 release behavior of the quercetin- and BMP-2-loaded group (orange line) and the only-BMP-2-loaded group (brown line) is shown
