Outline of Final Research Achievements

We aimed to apply the measurement method of cell membrane water permeability established in experiments in vitro to in vivo experiments in rodents. Based on the evidences we also tried to apply it to human MRI.
Additional in vitro experiments were conducted to strengthen the evidence for in vivo applications. A in-vivo-like phantom experiment was performed to adjust the in vivo MRI protocol. In order to quantitatively assess the effects of microcirculation that do not exist in in vitro experiments, the effects were investigated using a unilateral chronic low reflux model mouse. Based on the results of basic research, we obtained feasible results about cell membrane permeability in human using our proposal method.

Academic Significance and Societal Importance of the Research Achievements

腫瘍の悪性度や治療効果で大きく変わるといわれている細胞膜水透過性であるが、これは摘出標本で測定することが困難で、生体そのままでの測定が必要となる。細胞レベルでの測定報告は多いものの、In vivo応用されたケースは極めて少なく、ヒトへの応用性のあるものは皆無といってよい状況であった。そのような中で、本手法は広く臨床で応用されているMRIを用いた非侵襲的な測定技術で、実現できれば新たなバイオマーカーとして有益な生体情報を提供できる可能性がある。
本研究で得られたIn vitro・In vivoの結果から近い将来の臨床応用の可能性を示す複数のエビデンスが得られたことは大きな意義があると考えられる。
