I have engaged in development of education movies demonstrating real-time biophysical phenomena in vivo and in vitro by two photon laser microscopy. Two photon laser microscopy is a new method based on two photon excitation which generates new photons inside the animal body for visualizing real-time images of cells. These real-time movies demonstrating dynamic phenomena occurring inside our body probably enhance the understanding of students studying biological science. In this study I have obtained the real-time images of normal cells in gastrointestinal tracts, liver, pancreas, kidney, brain, and vessels. I have also observed the real-time images of cancer cells in intestines, which gives me an opportunity to develop a novel method to identify very small cancers at the ultra-early stages. The new method has been submitted as an international patent under the financial support from JST. The education movies obtained in this study will be opened in a free internet service.

我曾从事教育电影的发展，演示实时生物物理现象，在体内和体外的双光子激光显微镜。双光子激光显微术是一种基于双光子激发的新方法，它在动物体内产生新的光子，用于实时观察细胞图像。这些实时电影展示了我们体内发生的动态现象，可能会增强学习生物科学的学生的理解。在这项研究中，我获得了胃肠道，肝脏，胰腺，肾脏，大脑和血管中正常细胞的实时图像。我还观察了肠道中癌细胞的实时图像，这使我有机会开发一种新方法来在超早期阶段识别非常小的癌症。在JST的资助下，新方法已作为国际专利提交。在这项研究中获得的教育电影将在免费的互联网服务中开放。
