Cell proliferation of rBMSCs cultured with the extracts from the CaSiO3, Fe and 30CS powders on day 1 (a), day 3 (b), and day 5 (c). Confocal LSM images of the rBMSCs after culturing in the CaSiO3 (d), Fe (e) and 30CS (f) scaffolds for 1 day. Relative gene expressions of the rBMSCs (g–h) cultured with the extracts of the CaSiO3, Fe, and 30CS powders at a concentration of 50 mg/ml. Compared to the Fe scaffolds, the 30CS scaffolds significantly promoted the bone-related gene expression of rBMSCs
