Outline of Final Research Achievements

We have been studying mesenchymal stem cells (MSCs) induced from human induced pluripotent stem cells (iPS cells) to investigate their therapeutic effects on animal models of kidney disease. We also established kidney disease model animals, administration protocols of induced MSCs (iMSCs), and evaluation protocols for therapeutic efficacy. As a result, we have demonstrated a certain therapeutic efficacy of iMSCs for refractory kidney diseases. Further studies are underway to maximize the therapeutic efficacy of iMSCs. The establishment of novel treatment methods using iMSCs is highly promising.

Academic Significance and Societal Importance of the Research Achievements

今回我々は、腎疾患領域における、ヒト人工多能性幹細胞(iPS細胞)を用いた新規治療法開発の可能性について検討した。当教室ではこれまで間葉系幹細胞(MSC)を用いた新規治療法の開発に注力してきた。しかし、MSCは採取できる量に限界があり、均一的な性質や効果を示すとは限らず、また継代を重ねることで“細胞的老化”を示すとされてきた。今回の我々の研究では、iPS細胞からMSCを誘導することで、これまでのMSC治療の問題点を克服することにつながると考えられた。さらにiPS細胞は治療効果を高める工夫も追加しやすく、通常のMSCよりも高い治療効果が期待できる。
