Abstract/OtherAbstract:
Induced pluripotent stem (iPS) cells possess the ability of self-renewal and can differentiate into cells of the three germ layers, both in vitro and in vivo. Here we report a new method to efficiently induce differentiation of mouse iPS cells into the odontogenic lineage. Using ameloblasts serum-free conditioned medium (ASF-CM), we successfully generated ameloblast-like cells from mouse iPS cells. Importantly, culturing mouse iPS cells in ASF-CM supplemented with BMP4 (ASF-BMP4) promoted odontogenic differentiation, which was evident by the upregulation of ameloblast-specific as well as odontoblast-specific genes. On the other hand, culturing mouse iPS cells in ASF-CM supplemented with noggin (ASF-noggin), an inhibitor of BMP4, abrogated this effect. These results suggest that mouse iPS cells can be induced by ASF-BMP4 to differentiate into ameloblast-like and odontoblast-like cells. The results of our study raise the possibility of using patient-specific iPS cells for tooth regeneration in the future. Copyright © 2013 John Wiley & Sons, Ltd.
