Description
まず、プローブを細胞中に導入する。

上記得られたシグナルをもとに、細胞の分化状態を評価することができる。
以下のプローブを用いた。
Actb MB:配列番号2の5’末端をTYE665で、3’末端をIBRQ(lowa black RQ)でそれぞれ修飾したプローブ。配列番号1は、1~6位と24~30位がステム領域を構成する相補的な配列であり、7~23位がループ構造を構成する配列である、モレキュラービーコンである。
2-1.ゼラチンナノ粒子の調製
ゼラチン(新田ゼラチン株式会社製、G-2613P)を24mlの0.1Mリン酸緩衝水溶液(pH5.0)に37℃で溶解させた。この溶液に対して、適量のエチレンジアミンを添加した。さらに、塩酸水溶液を添加して、溶液のpHを5.0に調整した。さらに、適量の1-エチル-3-(3-ジメチルアミノプロピル)カルボジイミド塩酸塩を添加し、0.1Mリン酸緩衝水溶液の添加によってゼラチンの濃度を2質量%に調整した。この溶液を37℃で4時間撹拌して、ゼラチンが有するカルボキシル基へエチレンジアミンを導入した。その後、反応物を再蒸留水で3日間透析して、スラリー状のカチオン化されたゼラチンを得た。その後、相分離誘起剤としてのアセトンを添加し、50℃で混合して、スラリー中に析出した粒子を回収し、純水で洗浄して、カチオン化されたゼラチンナノ粒子を得た。このカチオン化されたゼラチンナノ粒子を、cGNSとする。
cGNSと、Pdk1 MBとを室温で15分間混合し、その後、遠心分離して水で洗浄して、上記プローブを担持するゼラチンナノ粒子を得た。このゼラチンナノ粒子を、cGNS(Pdk1 MB)とする。
3-1.Pdk1の発現量と分化マーカー遺伝子の発現量との比較
マウスES細胞(EB5、2×105cells/well)を6wellプレートに播種し、未分化状態を維持するために添加したleukemia inhibitory factor(LIF)の存在下で48時間培養した。その後、OptiMEMに培地交換し、LIF添加あり、およびLIF添加無しの条件でさらに培養した。1日、2日、および3日培養時点でそれぞれの培地から細胞を回収し、RNAを抽出し、逆転写によりcDNAの合成を行った。さらに、qRT-PCRにより、Pdk1、多能性マーカーであるOct-3/4、Sox2およびNanog、ならびに初期分化マーカーであるGata4、Gata6およびSox17(胚体内胚葉マーカー)、TおよびGSC(胚体中胚葉マーカー)、Pax6およびNestin(胚体外胚葉マーカー)、ならびにEomesおよびCdx2(胚体栄養外胚葉マーカー)の増幅を行った。ΔΔCt法により、まずActbを内部標準として使用してこれらのマーカーのmRNAの発現量を標準化し、さらに、LIF添加無しの条件でのこれらのmRNAの発現量に対して、LIF添加ありの条件でのこれらのmRNAの発現量を標準化した。
マウスES細胞(EB5、2×105cells/well)を6wellプレートに播種し、未分化状態を維持するために添加したleukemia inhibitory factor(LIF)の存在下で48時間培養した。その後、OptiMEMに培地交換し、LIF添加あり、およびLIF添加無しの条件でさらに培養した。1日、2日、および3日培養時点でcGNS(Pdk1 MB)を10μg/mL添加し、1hr共培養した後に蛍光顕微鏡で観察した。
マウスES細胞(EB5、2×105cells/well)を6wellプレートに播種し、未分化状態を維持するために添加したleukemia inhibitory factor(LIF)の存在下で48時間培養した。その後、OptiMEMに培地交換し、cGNS(Pdk1 MB)を添加して1時間の共培養を行った。また、cGNS(Pdk1 MB)の代わりに、カチオン性脂質(リポソーム)からなる遺伝子導入試薬であるLipofectamine 2000とPdk1 MBとの複合体、またはPdk1 MB単体を添加して、同様に1時間の共培養を行った。その後、細胞をPBSで洗浄し、さらに6時間の培養を行った後に、蛍光顕微鏡で観察した。
4-1.Pdk1の発現量と分化マーカー遺伝子の発現量との比較
マウスES細胞(EB5、2×105cells/well)を6wellプレートに播種し、未分化状態を維持するために添加したleukemia inhibitory factor(LIF)の存在下で48時間培養した。その後、神経分化培地(NDiff227)に培地交換し、LIF添加あり、およびLIF添加無しの条件でさらに培養した。4日、7日、および9日培養時点でそれぞれの培地から細胞を回収し、RNAを抽出し、逆転写によりcDNAの合成を行った。さらに、qRT-PCRにより、多能性マーカーであるOct-3/4、Sox2およびNanog、神経前駆細胞マーカーであるPax6およびNestin、ならびにニューロンマーカーであるTubb IIIの増幅を行った。ΔΔCt法により、まずActbを内部標準として使用してこれらのマーカーのmRNAの発現量を標準化し、さらに、LIF添加無しの条件でのこれらのmRNAの発現量に対して、LIF添加ありの条件でのこれらのmRNAの発現量を標準化した。
マウスES細胞(EB5、2×105cells/well)を6wellプレートに播種し、未分化状態を維持するために添加したleukemia inhibitory factor(LIF)の存在下で48時間培養した。その後、神経分化培地(NDiff227)に培地交換し、LIF添加あり、およびLIF添加無しの条件でさらに培養した。LIF添加あり、およびLIF添加無しの条件でさらに培養した。4日、7日、および9日培養時点でcGNS(Pdk1 MB)を10μg/mL添加し、1hr共培養した後に蛍光顕微鏡で観察した。
5-1.標準細胞株の分化状態によるPdk1の発現量の変化の観察
マクロファージ様細胞株(RAW264.7細胞、2.0×105 cells、M0)をRPMI1640培地で12wellプレートに播種し、培養した。24時間後、100ng/mlのリポ多糖(LPS)および20ng/mlのインターフェロン-γ(IFN-γ)を加えて、マクロファージM1へと誘導した。その後、培地にcGNS(Pdk1 MB)を添加して、蛍光顕微鏡で観察したところ、全ての細胞からの蛍光発光が観察された。
Balb/cマウス腹腔内に5mlのリン酸緩衝水溶液を投与して、腹腔内をよく洗浄した。その後、腹腔内洗浄液を回収して、12wellプレートに播種し、培養して、腹腔マクロファージを得た。当該腹腔マクロファージ用いて、5-1と同様の実験を行ったところ、マクロファージM1への分化を誘導した状態では、細胞からの蛍光発光が観察されたが、マクロファージM1への分化を誘導したところ、細胞からの蛍光は消失していた。
大腸癌細胞株について、試験2、試験3と同様の実験を行った。分化誘導により解糖系による代謝が優位である状態とした後にcGNS(Pdk1 MB)を添加して、蛍光顕微鏡で観察したところ、全ての細胞からの蛍光発光が観察された。一方で、ミトコンドリアにおける代謝が活性化されている状態とした後に、蛍光顕微鏡で観察したところ、細胞からの蛍光は観察されなかった。
