Background: Stem cells from human exfoliated deciduous teeth (SHED) are a mesenchymal stem cell type and have recently attracted attention for their high proliferative rate, multipotency, and immunosuppressive properties. However, SHED have not yet been investigated for anticancer properties. We therefore investigated whether SHED can be used as a treatment modality, particularly for anti-glioma therapy. Methods: In vitro, we examined the mobility of SHED and their ability to migrate towards glioma-conditioned medium and specific growth factors secreted by malignant gliomas. In vivo, we transplanted SHED into the left hemisphere of nude mice that had been previously implanted with human malignant glioma U87 cells into the right hemisphere. We assessed whether SHED had tumorigenic potential. Results: SHED exhibited strong migration ability towards malignant glioma in both in vitro and in vivo assays. In vitro, SHED migrated towards glioma-conditioned medium and specific growth factors such as stem cell factor, platelet-derived growth factor BB, C-X-C motif chemokine ligand 12, and vascular endothelial growth factor. SHED were accumulated around tumor cells in the contralateral hemisphere 1 week after transplantation. Moreover, SHED remained in the brains of nude mice 150 days after transplantation. Finally, we verified that SHED had no malignant transformation or engraftment of SHED in the mouse brain. Conclusions: Our findings indicate that SHED can potentially be applied to track malignant glioma.
