Keywords不妊症 / 着床 / 子宮内膜
Outline of Research at the Start

現在の不妊治療の治療効率を向上するためには現在ブラックボックスである受け入れ側の子宮の着床能を前方視的に評価しその周期ごとの治療方針に反映させなければならない。これまでの我々の研究において、ヒトでは排卵期前に子宮内膜の電気生理学的パラメータを測定する事でその周期の子宮内膜の受容能が前方視的に評価できる事を明らかにした。本研究では、この物質的基盤を明らかにするために月経による子宮内膜の再生機構について、マウスモデルを用いて基礎研究を行う。将来的に、電気生理学的評価の物質的基盤を検討する事でヒト子宮の着床能を前方視的に評価する装置システムの精度の向上だけでなく、治療への応用をめざす。

Outline of Final Research Achievements

Although the social demand for assisted reproductive technologies treatment is high worldwide, the efficiency of the treatment is not sufficient enough.
To improve the efficiency of current treatment, it is necessary to evaluate the prospect of uterine receptivity in each menstrual cycle and incorporate it into the treatment strategy for each cycle. Our previous studies have suggested that the prospect of uterine receptivity can be predicted by measurement of electrophysiological parameters in the uterine cavity before ovulation. In the present study, we investigated this on a molecular basis in the mouse models, focusing on the human menstrual cycle, to assess the degree of the reconstruction of the endometrium.

Academic Significance and Societal Importance of the Research Achievements

これまで、月経周期ごとに子宮の着床能を前方視的に評価するようなシステムはなかった。排卵前の子宮内膜はエストロゲンの作用により増殖だけして、排卵期以降にプロゲステロンの作用により着床能を有するための準備をすると考えられてきたものの、少なくともヒトの子宮内膜の受容能は排卵期より前に運命が決まっている事が示唆された。今回の研究により子宮内膜の再生の度合いを評価できるようなシステムと物質的基盤が一部解明され、子宮内膜の再生を標的とした治療に応用できる可能性がある。
