| Research Abstract |
In the present study, we introduced a microdissection technique which can be used in a stereoscopic scanning electron microscope (3D-SEM) and applied this technique to the study on the three-dimensional ultrastructure of cells and tissues.
We developed preparation methods suitable for dissecting samples by the two micro-manipulators in the 3D-SEM. We also used the improved manipulators with a needle, micro-scissors and micro-forceps. Using these micro-manipulators, we succeeded in dissecting some tissue samples(e.g, kidney, inner ear, etc) in a 3D-SEM. Thus, the SEM-dissection technique in a 3D-SEM is very useful for the morphological study on cells and tissues.
