The evaluation of mineralization and calcium content in odonto/osteoblasts from four types of dental stem cells. a Odonto/osteoblasts from DPSCs had the strongest staining intensity using ALP and Von kossa stains (scale bar = 100 µm). b ALP activity and calcium content were highest in the odonto/osteoblasts from DPSCs. Data are represented by the mean ± SD of four independent experiments. Lettered subscripts indicate statistical differences between groups (p < 0.05)
