| Research Abstract |
We have characterized the multi-differentiation potency, phenotypic marker expression and trascriptome profile of dentalpulp derived stem cell from adult wisdom teeth (DPSC) and exfoliated deciduous teeth (SHED). The data showed that both SHED and DPSC expressing multiple neural linage markers are able to differentiate neuron, astrocyte, oligodendrocyte, osteoblast, adipocyte and chondrocytes. Furthermore, we have optimized the protocol allowing a specific differentiation of SHED and DPSC to tyrosine hydroxylase expressing dopaminerigic neurons. In pre-clinical analysis, we have found remarkable therapeutic benefits of SHED and DPSC for treatment of spinal cord injury, hypoxic brain injury and Parkinson’s disease. In addition to their remarkable neuro-regenerative activities, we did not observe the malignant transformation of engrafted SHEDs 8 weeks after theirimplantation. SHEDs and DPSCs can be obtained from exfoliated deciduous and impacted adult wisdom teeth without adverse health effects. Thus, there are few ethical concerns regarding their clinical use. We propose that tooth-derived stem cells may be an excellent and practical cellular resource for the treatment of various CNS diseases.
