本実施例では、マウスエピブラスト幹細胞(EpiSC)を用いてキメラマウスの作製を試みた。
そこで、発明者らは、様々な因子を検討したところ、抗アポトーシス因子として知られるBcl−2遺伝子を導入したEpiSCは、キメラ形成能を有することを見出した。
本実施例では、EpiSCよりもさらに分化した内胚葉系列前駆細胞であっても、Bcl−2遺伝子の強制発現によりキメラ動物の作製に利用できるかを検証した。
本実施例では、Bcl−2遺伝子以外の遺伝子として、Bcl−2同様に抗アポトーシス機能を有するBcl−xL遺伝子(Genbank Accession No.BC089016)の導入を試みた。
実施例2A〜4Aでは、アポトーシスを抑制する処理をした細胞は、キメラ形成能を向上させていた。そこで、本実施例では、アポトーシスを抑制する処理をしたEpiSCの遺伝子発現解析を行い、EpiSCおよびES細胞の遺伝子発現と比較した。
上記実施例では、アポトーシス抑制因子として、Bcl−2またはBcl−xLを用いたが、本実施例では、さらにXiapおよびcrmAをアポトーシス抑制因子として細胞に強制発現させ、細胞のキメラ形成能を確認した。
実施例1Bでは、アポトーシス抑制処理をしない場合でも、割合は低いながら内胚葉系列前駆細胞がキメラに寄与した。エピブラスト幹細胞においても同様の結果が得られるかを確認するため、本実施例では、アポトーシス抑制処理がなされていないエピブラスト幹細胞のキメラ形成能を検証した。
本実施例では、内胚葉前駆細胞と同様に、始原生殖細胞においても細胞死抑制によってキメラの作製が可能になるかどうかを検証し、さらに導入した始原生殖細胞の生殖細胞への寄与を確認した。
本実施例では、ヒトiPS細胞のキメラ形成能に対する、細胞死抑制処理の効果を検証した。
本実施例では、マーモセットES細胞のキメラ形成能に対する、細胞死抑制処理の効果を検証した。
実施例2A〜4A、1Bおよび2Bにおいてキメラ形成能の低い細胞またはキメラ形成能を有しない細胞を用いて、高効率にキメラ動物を作製できるようになった理由としては以下のようなことが考えられる。本実施例の結果を考慮すると、発生過程の細胞は、異なる時間腔得間的環境、例えば、本来の発生運命と異なる領域に置かれた際に細胞死またはアポトーシスを起こしている可能性が示唆される。そのため、本発明で観察された現象は、細胞のアポトーシスを抑制することにより、細胞は胚発生の段階が適合する時期まで生き延びることができるのではないかと考えられる。
