Differentiation of Human-induced Pluripotent Stem Cell-derived Dental Stem Cells through Epithelial-Mesenchymal Interaction
Research on tooth regeneration using human-induced pluripotent stem cells (hiPSCs) is valuable for autologous dental regeneration. Acquiring mesenchymal and epithelial cells as a resource for dental regeneration is necessary because mesenchymal-epithelial interactions play an essential role in dental development. We reported the establishment of hiPSCs-derived dental epithelial-like cell (EPI-iPSCs), but hiPSCs-derived dental mesenchymal stem cells (MSCs) have not yet been reported. This study was conducted to establish hiPSCs-derived MSCs and to differentiate them into dental cells with EPI-iPSCs. Considering that dental MSCs are derived from the neural crest, hiPSCs were induced to differentiate into MSCs through neural crest formation to acquire the properties of dental MSCs. To differentiate hiPSCs into MSCs through neural crest formation, established hiPSCs were cultured and differentiated with PA6 stromal cells and differentiated hiPSCs formed neurospheres on ultralow-attachment plates. Neurospheres were differentiated into MSCs in serum-supplemented medium. Neural crest-mediated MSCs (NC-MSCs) continuously showed typical MSC morphology and expressed MSC markers. After 8 days of odontogenic induction, the expression levels of odontogenic/mineralization-related genes and dentin sialophosphoprotein (DSPP) proteins were increased in the NC-MSCs alone group in the absence of coculturing with dental epithelial cells. The NC-MSCs and EPI-iPSCs coculture groups showed high expression levels of amelogenesis/odontogenic/mineralization-related genes and DSPP proteins. Furthermore, the NC-MSCs and EPI-iPSCs coculture group yielded calcium deposits earlier than the NC-MSCs alone group. These results indicated that established NC-MSCs from hiPSCs have dental differentiation capacity with dental epithelial cells. In addition, it was confirmed that hiPSCs-derived dental stem cells could be a novel cell source for autologous dental regeneration.
