PHA処理がブタ体細胞核移植卵の体外発生能に及ぼす影響(Effect of phytohemagglutinin(PHA) on nuclear transfer pig embryos in vitro)
ンドゥブイシ・マチェベ, 清水 聡一郎, 秦 仁樹, 大畠 一輝, 谷 哲弥, 加藤 容子
Journal of Mammalian Ova Research   36(1) 33-43   Apr 2019
本研究では、ブタ単為発生卵ならびに体細胞核移植卵の体外発生能に及ぼすPHAの影響を検討した。単為発生卵ではPHA処理するとミトコンドリア活性が向上することがわかった。体細胞核移植卵では細胞融合前にPHAで5分間処理すると卵割率と胚盤胞への発生率が有意に向上した。また、ミトコンドリア関連遺伝子であるATPase6とND1の発現量が有意に増加した。以上の結果から、PHAの前処理は、ミトコンドリア活性に影響を及ぼしてブタ体細胞核移植卵の体外発生能を向上させることが示唆された。(著者抄録)

【目的】哺乳動物では,個体が老化するにつれて生殖能力が低下する。すなわち,雌では,個体の老化に伴い卵子の老化も生じているためである。卵子の老化には,核(染色体)と細胞質中因子の両者に生じる様々な変異が含まれており,一度生じた卵子の老化を消去することは困難で,老齢個体から採取した卵子を若返らすことは容易にはできない。一方,近年,母体の栄養状態や給餌内容(栄養素)が,母体の生殖能力に影響を及ぼすことが相次いで発表されている。そこで,本研究では,老齢マウスの生殖能力を経時的に検討するとともに,給...

【目的】ICSIにより卵母細胞内に注入された精子は,先体反応や卵母細胞膜との融合を経ておらず,卵細胞質内において先体および完全な細胞膜を有したまま存在することになる。そのため,先体および精子細胞膜の存在が,ICSIでの一連の受精現象の不成立,特に精子核の脱凝縮や前核形成の遅延や阻害を引き起こしている可能性が考えられる。TritonX (TX)やリゾレシチン(LL)といった界面活性剤で精子を前処理して,予め細胞膜を除去し,先体反応を誘起すると,マウスICSI卵の産仔作出率が向上することが報告...

【目的】マウス体細胞核移植クローンの作出効率,特に移植後の後期発生率は依然として低く,その改善が求められている。核移植胚では発生を通して多くの遺伝子が異常な発現を示しており,低発生能の一因であると考えられる。我々は核移植胚の遺伝子発現に着目し,その発現を指標に高発生能を有すると推察できる核移植胚を,移植前選別することによる効率の改善を試みてきた(第106回本学会等)。本実験では,Oct3/4,Nanogの発現様式を指標として胚盤胞期での選別を行い,体内発生能を検討した。【方法】核移植のドナ...
