| Research Abstract |
Using cell clones derived from the human dental pulp tissue, we studied genes involved in the differentiation of dental pulp stem cells by analyzing cell growth, differentiation potentials, and gene expression profiles. Some genes involved in signal networks (such as Wnt and Notch signaling pathways) and some gene clusters (such as carbohydrate metabolism-, cell cycle- and differentiation-relating genes) turned out up- or down-regulated in the differentiation process. To elucidate the function of sex hormone receptors on dental pulp cells, the gene expression profiles of the dental pulp cells treated with sex hormones were analyzed. We found that sex hormones could act directly on human dental pulp cells through sex hormone receptors.
