| Outline of Final Research Achievements |
Essential proteins for lingual papillae morphogenesis are likely present during embryonic development. We searched for the responsible genes and selected candidates involved in lingual papillae morphogenesis. Then to establish regeneration techniques, preliminary transfection of siRNA was performed. Transfection of the synthesized siRNA together with vectors for fluorescent proteins expression into rat embryonic lingual tissues was performed using the electroporation method. After the transfection, the lingual tissues were organ-cultured and observed. Twenty-four hours after the transfection, fluorescence markers started illuminating inside of the lingual tissues and were continuing to glow up to the 72 hour intervals. However, the quality of fluorescence was being occasionally unstable. Optimization of electric pulse parameters was required in order to maintain cell viability and more efficacious transfection methods also would be required.
