  We isolated mouse bone marrow stroma-derived adult stem cells (MMSC-3) which could be induced for the differentiation not only into mesodermal cells, but also into ectodermal and endodermal cells in vitro.  In order to investigate the possibility of MMSC-3 for the differentiation into odontogenic lineage, MMSC-3 was co-cultured with a rat dental epithelial cell line in the presence or absence of various extracellular matrices such as EMD, Matrigel or GFR Matrigel.  These investigaions revealed that 1) MMSC-3 was capable of differentiating into odontogenic cell lineage, 2) the odontogenic differentiation was promoted by the odontogenic epithelial cells.
