Outline of Research at the Start

本研究では、初代培養由来尿細管オルガノイドの作製を、数十例の腎摘出術を受ける患者から実施してライブラリ化し、個々の患者の特性を再現する、ヒトをベースにした病態モデルおよび薬効・毒性検証のプラットフォームとして確立することを目的とする。これにより、マウスと実際のヒトの間を埋め、かつヒトの個体差をも反映する病態モデルとして活用し、慢性腎臓病を中心とした慢性腎疾患の病態解明と創薬に応用していくことを目指す。

Outline of Final Research Achievements

We established 21 cases of tubular epithelial primary culture cells derived from the resected kidneys of patients with human renal cancer and other diseases, and succeeded in organoidization in almost all of them. We set out to artificially mimic chronic kidney disease (CKD) by drug stimulation of tubular organoids derived from kidneys with normal renal function and found that artificial CKD tubular organoids can mimic most of the phenotypes of CKD, including cellular senescence and inflammatory and fibrogenic cytokine secretion. We also found that our method can be used to establish primary cultured cells from resected kidney fragments and to produce organoids, all under identical conditions. These results are being submitted for publication or will be submitted soon.

Academic Significance and Societal Importance of the Research Achievements

これまで慢性腎臓病の病態モデルは完全な不死化培養細胞株によるものかマウスによるものしか存在しなかった。培養細胞株によるものは、実際の腎臓からの乖離が著しく、また、マウスによるモデルでは、数十年単位で進行する慢性腎臓病を寿命2年のマウスで再現することには限界があった。我々は、ヒトの腎臓に直接由来する初代の上皮細胞でオルガノイドを作製し、さらにそれを人工的に慢性腎臓病の状態にすることに成功している。また末期腎不全の患者の腎臓からのオルガノイド樹立にも成功している。これらの2つの尿細管オルガノイドによる慢性腎臓病モデルは、腎機能を改善しうる治療薬を探索するための重要なツールとなることが期待できる。
