Outline of Final Research Achievements

The purpose of this study is establishment in vitro perfusion culture system and to elucidate the effects for renal organoids (developmental stage) originated from human iPS cells on perfusion stimulation. With the air-liquid interface perfusion culture system, renal organoid cultured at an adequate perfusion rate was caused liquid diffusion and improved the organization by epithelial cells, while decayed it at a perfusion range above the adequate value. It was suggested that high perfusion rate caused a decrease in signal transduction for renal development in renal organoids.

Academic Significance and Societal Importance of the Research Achievements

組織工学研究の中で、かん流培養は3次元組織に栄養酸素を供給、長期間培養を可能にするとされ、心筋組織等の維持・発達が報告されている。このような中で、腎臓発生に対する適切なかん流刺激の必要性を提唱した本成果は、3次元組織かん流培養技術において、組織の種類、発達度を考慮した条件の重要性を示した。今後、生体外構築された様々な組織において、適正値の設定により長期維持、高機能化が可能になることが期待される。また情報の限られた胎児期発生への影響を、生体外で解析する本研究成果は、今後の創薬研究や医学研究に有効なツールに発展する可能性が示唆された。
