Fig. 4From: Hydroxyapatite microbeads containing BMP-2 and quercetin fabricated via electrostatic spraying to encourage bone regenerationMicro-CT analysis of bone formation in rat calvarial defects. A 3D-reconstructed images of each group at 4 and 8 weeks. Quantitative analysis of B bone volume (BV), C bone surface area, D bone volume fraction (BV/TV), and (E) bone mineral density (BMD) within defects. Scale bar = 1 mm. p < 0.05 compared to the blank (*), HAp (†), Qct (‡), and BMP-2 (§) groupsBack to article page
