| Outline of Final Research Achievements |
We examined the effect of gravity to the development of vestibular hair cell. In the microgravity environment, the development of hair cell from mouse ES cells seemed to be suppressed. Also we established the organ culture method in the microgravity environment using 3D clinostat system. We observed the hair bundle maintenance of vestibular hair cells both in normal gravity and in microgravity environment. Compared with normal gravity, the number of hair bundle was decreased in the the microgravity environment, but there was no significant difference. So gravity might be important for the development of vestibular hair cell.
