本研究では、低コストで容易に得られる物質を用いて、mESCからの神経細胞分化の簡便かつ効果的な方法を確立した。この方法では、2日間の胚体形成後に6日間のRA誘導が行われ、MESCsのNPCへの分化を効果的に促進することができる(フェーズI-プロトコル3)。第II相分化のために、N2B27培地II(フェーズII-プロトコル3)は、NPCからニューロンへの分化を最も効果的に誘導する。成功を確実にするため?...

胚性幹細胞(ESC)は多能性であり、神経前駆細胞(NPC)に分化し、その後、特定の条件下でニューロンに分化することができる1。ESCベースの神経新生は、神経新生を模倣するための最良のプラットフォームを提供し、したがって、発生生物学研究のための有用なツールとして機能し、潜在的に再生医療2、3を支援する。過去数十年の間に、トランスジェニック法4のような胚性神経新生を誘導するための多くの戦略が報告されている、小分子5を用いて、3Dマトリックス微小環境6を用いて、および共培養技術7を用いた。しかし、これらのプロトコルのほとんどは、条件が制限されているか、操作が困難であるため、ほとんどの研究室での使用には適していません。
mESCからの効率的な神経分化を達成するために、操作が容易で低コストの方法を見つけるために、ここで組み合わせスクリーニング戦略を使用しました。図1に記載されているように、胚性神経新生の全過程を2相に分けた。フェーズIはmESCからNPCへの分化プロセスを指し、第II相はNPCからニューロンへのその後の分化に関連する。容易な操作、低コスト、容易に利用できる材料および高い分化効率の原則に基づいて、フェーズIの7つのプロトコルおよびフェーズIIの3つのプロトコルは、伝統的な付着単層培養システムまたは胚体形成システム8、9に基づいて選択された。両相におけるプロトコルの分化効率を、細胞形態観察および免疫蛍光アッセイを用いて評価した。各フェーズの最も効率的なプロトコルを組み合わせることで、mESCからの神経分化のための最適化された方法を確立しました。

neuronal differentiation from mouse embryonic stem cells in vitro

マウス胚性幹細胞(mESC)の神経分化は、神経新生に関与する重要なメカニズムを解明し、再生医療に役立つ可能性のあるツールです。ここでは、組み合わせスクリーニングの戦略を用いて、 インビトロでのmESCからのニューロン分化のための効率的かつ低コストの方法を確立しました。ここで定義された条件の下で、2日間の胚体形成+6日間のレチノイン酸誘導プロトコルは、ネスチン陽性であるよく積み重ねられ、神経突起のようなA2loxおよび129誘導体の形成によって見られるように、mESCから神経前駆細胞(NPC)への迅速かつ効率的な分化を可能にする。胚体の健全な状態とレチノイン酸(RA)が適用される時点は、RA濃度と同様に、その過程で重要である。NPCからニューロンへのその後の分化において、N2B27培地II(神経基底培地によって補完される)は、神経細胞の長期的な維持および成熟をよりよく支えることができる。提示された方法は、高効率、低コスト、操作が容易であり、神経生物学や発生生物学の研究のための強力なツールとなり得る。

2日間の胚体形成+ 6日間のRA誘導は、MESCのNPCへの分化(フェーズI)を導くのに最適です。MESCsのNPCへの分化を最も促進する最適なプロトコル(フェーズI)を決定するために、A2loxと129 mESCsの両方で7つのプロトコルをテストし、各群の分化状況を光顕微鏡で監視した。 図3Aに示すように、ほとんどのA2loxおよび129誘導体は「2日間の胚体形成+6日間のRA誘導」処置(フェ...
