ゲル培地ではない液体培地である、750μLのStemspanACF(Stemcell Technologies)に、第1実施形態の実施例12で分離した5×104個の単核球細胞を懸濁させた。当該懸濁液をウェルディッシュの各ウェルに播種し、ウェルディッシュを37℃のCO2インキュベーター中に静置して、単核球細胞を培養した。
ゲル培地ではない液体培地である、750μLのStemspanACF(Stemcell Technologies)に、第1実施形態の実施例12で分離した1×106個の単核球細胞を懸濁させた。当該懸濁液をウェルディッシュの各ウェルに播種し、ウェルディッシュを37℃のCO2インキュベーター中に静置して、単核球細胞を培養した。3日後、750μLのStemspanACFを各ウェルに添加し、37℃のCO2インキュベーター中に静置した。
第2実施形態に係る人工多能性幹細胞の作製方法は、体細胞を用意することと、体細胞にRNAトランスフェクション試薬を用いて初期化因子RNAを導入することと、ゲル培地中で体細胞を初期化することと、を含む。
ウェルプレートの各ウェルに、1.5mLのPBSに対し、iMatrix−511(nippi)を0.5μg/cm2となるように希釈した基底膜マトリックスの希釈液を入れた。その後、ウェルプレートを37℃のインキュベーターに1時間以上入れた。次に、ウェルプレートの各ウェルから基底膜マトリックスの希釈液を取り除き、ウェルプレートの各ウェルに10%FBS培地に懸濁した繊維芽細胞を約1×105個播種し、繊維芽細胞を接着培養した。
ヒト血液細胞は健康な成人男性から入手した。また、修飾化mRNA(TriLink社)、非接着ディッシュ、15mLチューブ、50mLチューブ、フィコール、サイトフローメータ(BD)、CD34に対する抗体(Miltenyi Biotec)、CD3に対する抗体(Miltenyi Biotec)、MACS(登録商標)バッファ(Miltenyi Biotec)、T細胞培地、低血清培地(Opti−MEM(登録商標)、Gibco)、siRNA導入試薬(Lipofectamine(登録商標)RNAiMAX、ThermoFisherScience)、及びTRA−1−60に対する抗体(BD)を用意した。
リポフェクションを開始してから7日目に、細胞の一部を12ウェルプレートから取り出し、取り出した細胞を初期化され始めた細胞で特異的に発現する表面抗原であるTRA−1−60対する抗体であって、Allophycocyanin(APC)蛍光色素で標識された抗体で染色した。その後、蛍光活性化セルソータ(FACS(登録商標)、BD)で、TRA−1−60陽性細胞の割合を確認することによって、細胞においてリプログラミングが開始され、iPS細胞遺伝子が発現し、iPS細胞ができてくる事を確認した。
