Outline of Final Research Achievements |
Our group developed IVA (in vitro activation) as a novel treatment for POI (premature ovarian insufficiency) . The percentage of the ovarian tissue graft survival rate, which is grafted into the ovary or beneath the peritoneum is not 100%. We still have room for some improvement of graft survival rate to get many follicles in grafted ovarian tissues. As the result of our study, A VEGF (vascular endothelial growth factor)-releasing fiber mat increased the number of follicles in the grafted ovarian tissues and improved the graft survival rate of ovarian tissue.

Academic Significance and Societal Importance of the Research Achievements |
卵胞の発育率を改善させるために世界においてもさまざまな方法が報告されているが、いずれも成熟卵胞の獲得率は低いままである。原始卵胞が存在するが、発育しない状態である卵巣機能不全患者に対する治療法として、VEGF徐放剤が卵胞活性化療法の効果を更に改善させる可能性が高く、良好成熟卵子の獲得により卵巣機能不全患者の妊娠率を向上させる可能性が高い。また、卵巣組織の生着率改善だけではなく、他の臓器移植に対しても徐放剤の有用性が示された。
