Mesenchymal stem cells (MSCs) possess the ability to differentiate into non-mesodermal lineage, and examining their multi-potency will be beneficial for application in regenerative medicine. The present study investigated the differentiation capacity into neuronal cells of ectodermal lineage and pancreatic cells of endodermal lineage in each of MSC lines isolated from three samples of human dental papilla tissues (DPSCs). Isolated DPSC lines expressed CD13, CD44, CD73, CD90 and CD105 cell surface markers, and OCT-4, NANOG and SOX-2 transcription factors. Further, all DPSC lines differentiated into osteocytes, adipocytes and chondrocytes of mesodermal lineage, whereas telomerase activity was at a low level in all isolated DPSC lines. Following induction into neuronal cells of ectodermal lineage, the neuron-like morphological alterations and expression of neuro-filament M by immunocytochemical staining was observed in all types of DPSCs, and expression of neuronal cell-specific transcripts, NSE, MAP-2, and NESTIN was further confirmed by reverse transcription-polymerase chain reaction (RT-PCR). Moreover, following induction into pancreatic cells of endodermal lineage, all DPSC lines exhibited morphological alterations with DTZ-positive spheroid clusters, and expression of pancreatic cell-specific transcripts, INSULIN, PDX-1, and GLUT-2, was positively detected by RT-PCR. However, some of these clusters were negatively reacted with DTZ staining. The present results demonstrated that DPSCs exhibit differentiation capacity into neuronal and pancreatic cells of non-mesodermal lineage, and DPSCs could be an alternative source of MSCs for clinical applications.
