Research Abstract

胎仔生殖細胞の形成、分化や増殖・生存能の低下、減数分裂の開始、精原細胞への分化は、環境因子とそれに対するこれらの細胞の反応性の変化により制御されていると考えられる。しかしこういった過程を制御する分子機構はこれまであまり明らかになっていない。そこで本研究では、こういったことを解明する目的で、発生段階特異的あるいは性特異的に生殖細胞やその支持細胞で発現する遺伝子をサブトラクションcDNAスクリーニングにより単離し、その機能を解明することを目的とした。まず、始原生殖細胞の形成に関わる遺伝子の単離を目的に、始原生殖細胞で特異的に蛍光タンパク質であるGFPを発現するOct3/4GFPトランスジェニックマウスから単離した移動期始原生殖細胞と、全能性幹細胞を含む胚盤胞からcDNAを合成し、それらの間でサブトラクションスクリーニングを行い、前者で特異的に発現する遺伝子の候補を得た。さらにそれらの発現パターンをRT-PCRおよびin situハイブリダイゼーション法により調べ、移動期および生殖隆起内の始原生殖細胞で発現しているが、全能性幹細胞や体細胞組織では発現しない遺伝子を見いだした。また、胎仔生殖細胞の性分化、減数分裂開始を制御する遺伝子を得るために、12.5日胚の雄、雌の生殖隆起を用いて同様にサブトラクションスクリーニングを行い、雄生殖隆起で特異的に発現している遺伝子の候補を得た。今後、それらの発現パターンの詳細と機能を明らかにする。
