Research Area

This research team analyzes detailed morphological information in various researches of the life science field, which is acquired through ultrastructural techniques using transmission and scanning electron microscopy. In collaboration with many laboratories including within RIKEN, we have accumulated a large amount of experiences to improve methods for better morphology.
