| Outline of Final Research Achievements |
Odontogenesis is regulated by the sequential and reciprocal epithelial-mesenchymal interactions through the various growth factors and cytokines. We previously performed cDNA subtraction between mouse mandibles collected on embryonic days 10.5 and 12.0 to identify the genes, including protein phosphatase 2A inhibitor 2 (I2PP2A) and facioscapulohumeral muscular dystrophy region gene 1 (FRG1). In this study, we show the specific expression of I2PP2A and FRG1 during the mouse tooth morphogenesis. The expression and localization of FRG1 were also shown using the mouse odontogenic epithelial cell line. Our present findings indicate that I2PP2A and FRG1 may play important roles in mouse tooth morphogenesis.
