| Outline of Final Research Achievements |
The purpose of this project is to establish in vitro system to detect and recapitulate the unusual phenomena which could cause ictogenesis and epileptogenesis in EL mice at an early stage of neurodevelopment. To develop this system, EL-mice derived embryonic stem cells (EL-ESCs) were established. To analyze the processes of neural differentiation of EL-ESCs by modified NSS method which is a simple method to induce uni-directional differentiation of ESCs into neural stem cells (NSCs), EL-ESCs uni-directionally differentiated into NSCs as well as HK-ESCs which are derived from B57BL/6 mice as control. However, long term culture (at least 6 days under differentiation condition) promoted astrocytogenesis of EL-ESCs-derived NSCs, whereas NSCs derived from HK-ESCs mainly generating neurogenesis in this period. By contrast, NSCs established from both EL-ESCs and HK-ESCs normally proliferated under the proliferative condition.
