Outline of Final Research Achievements

We developed a system to elucidate neuromuscular pathology using motor neuron disease-specific iPS cells. (1) We created a reporter to visualize the neuromuscular junction (NMJ) and succeeded in visualizing and quantifying NMJ formation. (2) We succeeded in capturing part of the phenotype using disease-specific iPS cells of SBMA.

Academic Significance and Societal Importance of the Research Achievements

疾患特異的iPS細胞を用いることで、患者由来運動ニューロンや骨格筋を用いた解析が可能になる。また、本解析で進める解析法は、様々な運動ニューロン疾患や筋疾患における神経・筋病態の解明に応用可能であり、神経・筋疾患における新たな病態解明と治療開発へと発展するものである。
