| Outline of Final Research Achievements |
First, we analyzed the social functioning behavior of model animals administered with stem cells and the distribution of cells in the brain. We detected that the patient-derived stem cells was difficult to become GAD67 and Parvalbumin-positive GABA interneurons in the brain after administration, and social interaction behavior was decreased in the patient-derived stem cell administered group compared to the control and healthy-derived stem cell administered group. Next, the synapse forming ability of the GABAergic interneuron was analyzed by the actin motility of the precursor structure filopodia, and found the reduction of the filopodia movement in the patient-derived cells. We also found that the possibility of the influence of decreased expression of the transcription factor TBX1 against it.
