Outline of Final Research Achievements |
Cultured mouse and human dental pulp (DP) cells exhibited strong alkaline phosphatase (ALP) activity compared with mouse osteoblasts and human mesenchymal stromal cells (MSC). To explore candidate genes to explain the character of DP cells, we conducted a GeneChip microarray analysis to detect differences in expression between DP cells and osteoblasts or MSC. The mRNA level of tissue non-specific ALP and BMP-2 in mouse and human DP cells was strikingly higher than that in mouse osteoblasts or human MSC. In contrast, the mRNA level of ENPP1, which hydrolyzes nucleoside triphosphate (NTP) to inorganic pyrophosphate (PPi), in mouse and human DP cells was much lower than that in mouse osteoblasts or human MSC. The mouse and human DP cells were transplanted into the muscle of immunocompromised NOD/Shi-scid IL2Rg (null) (NOG) mice and then recovered after 2 months. Soft X-ray images showed that explants of DP cells but not control explants formed a dense mineralized mass.
