| Research Abstract |
The majority of cells in the subodontoblastic layer express Thy-1.Therefore, to clarify the characteristics of cells in the subodontoblastic layer, the differentiation ability of Thy-1-positive cells into mineralizing cells was analyzed in vitro and in vivo. Following stimulation with BMP-2, Thy-1-positive dental pulp cells showed accelerated induction of ALP activity. Additionally, subcutaneous implantation of these positive cells induced numerous mineralized matrix formations. These results collectively suggest that Thy-1-positive dental pulp cells localized in the subodontoblastic layer have the ability to differentiate into hard tissue-forming cells.
