| Research Abstract |
In order to reveal mechanism of filopodia protrusion, we have developed a novel microscopy to detect nano structures like cekk membrane in real time with high contrast. Unfortunately, this development was not achieved for 2 year, however, done after the grant. Since the present developments have some trouble as above mentioned, we developed biological assay system to quantify the dynamics of myosin-X, which is responsible for filopodia protrusion (J Biol Chem., 285, 19605). Furthermore, we developed superresolution microscopy to observe the cell membrane with 90 nm and 80 ms spatial-temporal resolutions (Biophys.J., 99, L50-52).
