(a) ALP staining in cultures of osteoblasts exposed to the different formulations of core-shell microspheres. (b) Alizarin red staining in osteoblasts exposed to the different formulations of core-shell microspheres. (c) Quantitative results for ALP production by osteoblasts exposed to the different formulations of core-shell microspheres, compared with the control group. (d) Quantitative results for Alizarin red staining in osteoblasts exposed to the different formulations of core-shell microspheres, and compared with the control group. (A) BMP-2/VEGF group; (B) BMP-2/blank group; (C) blank/VEGF group; (D) double/double group; (E) VEGF/BMP-2 group; (F) blank/blank group; (G) control group (no microspheres).
