Background

A recent research breakthrough has demonstrated that the ectopic expression of four genes is sufficient to reprogram human fibroblasts into inducible pluripotent stem cells (iPSCs). However, whether human dental pulp cells (DPCs) could be reprogrammed into iPSCs remains an open question. In this study, we demonstrated that DPCs from deciduous and permanent teeth can be reprogrammed into iPSCs without c-Myc and had the capacity to differentiate into neuron-like cells.

Methods

DPCs were obtained from donors and reprogrammed into iPSCs using retroviral transduction with SOX2, OCT4, and KLF4. Then, these iPSCs were differentiated into neuron-like cells. Microarray and bioinformatics were used to compare the gene expression profile among these iPSCs and iPSC-derived neuron-like cells.

Results

The DPCs displayed a high vitality and capability to quickly restart proliferation and expressed elevated pluripotency similar to mesenchymal stem cells. According to our results, DPC-derived iPSC colonies that could be subcultured and propagated were established as early as 10 days after transduction, in comparison with the skin fibroblast (DPC-derived iPSCs) without c-Myc presented embryonic stem cell-like properties and the pluripotent potential to differentiate into neuron-like cells, which resemble neurons both morphologically and functionally.

Conclusion

The human DPCs from deciduous and permanent teeth can undergo reprogramming to establish pluripotent stem cell lines without c-Myc. These surgical residues, usually regarded as medical waste, can be used as an alternative source of pluripotent stem cells for personalized medicine."xsd:string
