We obtain and analyze ultrastructural information of cells and tissues by utilizing electron microscopy for elucidation of principles of life towards applied research.
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.
- Regulation of adherens junction remodellig by forces using alpha-catenin as a mechanotransducer.
- Molecular mechanism of perception of dead cells and signaling of wound closure in cell sheets.
- Role of force generated by myosin II on establishment of epithelial polarity.
