演題: Flows and stagnation in the brain-forming tectonics 脳形成テクトニクスにおける流れと澱み

講演要旨

Recent 3D live imaging on cells consisting of the developing cerebral cortex has been deepening my impression that the embryonic brain wall is filled with a variety of cellular flows but it also has transient or growing structures where cellular stagnation does occur. Given that these physically opposing events coexist in a spatiotemporally associated manner, it would be meaningful to dissect tissue-forming (morphogenetic) cellular events with an analogy to “tectonics” (which has originally been used to describe movements of mantle plates but can also be used for developing tissues [Blanchard et al., Nat. Methods 2009]). In this talk, I will show two interesting examples of “brain-forming tectonics” where neurons and neural progenitors are physically interacting with each other as mutually opposing elements (i.e., flowing and stagnating components), with analogies to landslides and mantle plumes for discussing “geological” contributions to the formation of the cerebral cortex.
