Outline of Final Research Achievements |
We have attempted to develop a novel animal model that individual immunodeficient mouse (SCID-hu) possesses the common characteristics of endometriosis: (1) transplanted endometrial tissue in the abdominal cavity, (2) immune response against it, and (3) menstrual-like hormone cycle. In fact, SCID-hu mice engrafted with intra-abdominal endometrial and intra-vessel myeloid tissues and ovariectomized ICR mice regulated with estrogen secretion has been completed, respectively. Although supported period has been already passed by, we are estimating the novel model possessed with all factors of endometriosis, 1, 2 and 3.

Academic Significance and Societal Importance of the Research Achievements |
子宮内膜症は一部の霊長類種でしか自然発症せず、解剖学的並びに生理学的特徴の相違から自然発症しないマウスを用いた疾患モデルでは子宮内膜症の表現型の一部しか再現できない。本計画のマウスは、カニクイザルの子宮内膜組織、免疫細胞、月経様性周期が付与された、これまでにない、霊長類に見られる子宮内膜症のすべての表現型を有している。子宮内膜症の探索的研究は、部分的な表現型を有する疾患モデル動物を用いることで、研究開発の拡がりが妨げられていた。このモデル動物の開発は、子宮内膜症の基礎的並びに探索的研究に大きく貢献する。
