| Outline of Final Research Achievements |
In this study, we investigated the mechanism of morphological self-renewability of radial glia (RG) during the development of the mammalian cerebral cortex, and the importance of this ability on the tissue architecture. We found that RG has the ability to regenerate the apical endfoot, even if it is lost by the perturbation of the spindle orientation, at the proliferative stage of the brain development. We also found that this morphological robustness is reduced at the neurogenic stage, suggesting that the change in morphological self-renewability is a key to understand the mechanism of the generation of outer RG, which forms an additional proliferation zone, OSVZ, at the late stage of the neurogenesis.
