| Research Abstract |
By using transgenic mouse which enabled us to trace NC-derived or mesodermal cells, we showed that dental mesenchyme was composed of mainly NC-derived cells, whereas half of bone marrow(BM) mesenchyme was composed of cells other than NC-derived and mesodermal cells. Furthremore, a colony-forming unit-fibroblast(CFU-F) assay indicated that CFU-Fs in the dental pulp are derived from NC, and BM are derived from both NC and mesodermal cells. Furthermore, we showed that dental mesenchyme supported the differentiation of B lymphocytes and osteoclasts.
