Quantified immunocytochemical analysis of odonto/osteoblasts. a Immunofluorescence staining revealed positive expression of odontoblast specific markers (ALP, DMP-1, and DSPP) in odonto/osteoblasts from all dental stem cells. Nuclei were stained with DAPI (scale bar 25 µm). b All marker proteins positive cells were showed in odonto/osteoblasts from DPSCs, indicating that DPSCs were the highest potential stem cell source for in vitro odontoblastic differentiation. Data are represented by the mean ± SD of four independent experiments. Lettered subscripts indicate statistical differences between groups (p < 0.05)
