MESC 行派生は日常的に多くの実験室で使用されるよく知られているプロシージャが、その効率は常に多能性維持を妨げることができる複数の要因のために期待高。本稿で示す、ステップバイ ステップ、シンプルで信頼性のあるプロトコルを使用して高効率 mESC ラインを確立する方法。これらの効率は文献で報告されたものに似ています。

胚性幹細胞 (ESC) は、自己更新または [特定の条件1を区別する能力を保持する着床前胚由来多能性細胞です。これらのプロパティに基づいて、esc キー、再生医療、疾患モデル作製、組織工学研究2便利なツールとなっています。
ESC は、初めて着床前マウス胚、低成功3,4マウス ESC (mESC) 線を元から派生しました。長年、導出効率残った多能性体外を維持が困難なのため、低。その上フィーダー細胞の5導出の効率を向上させる存在促進コロニーの添付ファイルと、核型安定性6、多能性維持の改善にプロトコル リードのいくつかの変更。最も重要なだった白血病抑制因子 (LIF) のまた mESC 培7、8、129S2 寛容な背景9からの胚の使用と mESC を添加した培地での培養が定義されています。血清、潜在的な差別化要因10の無料。最近では、説得力のある証拠はまた mESC 培 (2 i として知られている) するシグナル伝達経路の 2 つの小分子変調のカクテルの多能性を維持するために最善であることを示しています。マイトジェン活性化タンパク質キナーゼ (MAPK) 経路を阻害することによって分化信号を減らす、PD0325901 MEK 阻害剤の GSK3β 阻害剤 CHIR99021 は、低密度で細胞の生存を高める組み合わせから成るカクテル 2i11wnt シグナル経路を活性化。
本稿では効率的に mESC 行をマウス胚盤胞に由来する単純なプロトコルをについて説明します。LIF と血清交換12導出培にフィーダー細胞に寛容な系統からの胚を培養標準の手順を従ってください。このプロトコル、mESC ラインは、2 i の中で得られたものと同等の効率で派生できます。これにもかかわらず、非寛容な系統を扱うときに多能性維持、または可能性のある問題を回避する 2 i を追加できます。

derivation of stem cell lines from mouse preimplantation embryos

マウス胚性幹細胞 (mESC) の導出は、着床前の胚からの多能性細胞が確立されたプロセスです。これらの行は、自己更新または特定の条件の下で区別するための能力を保持します。これらのプロパティにより mESC、再生医療、疾患モデル作製、および組織エンジニア リングの研究に有用なツールです。寛容なマウス系統白血病阻害因子を添加した培地でフィーダー細胞から胚盤胞培養 mESC 行高導出効率 (60 ~ 80%) を取得するための単純なプロトコルを説明します。プロトコルは、派生メディア (2i 中) に 2 つの小分子阻害剤のカクテルの簡単な付加によって効率的に mESC 行を非感受性マウス系統から派生にも適用できます。準備とフィーダー細胞、コレクションと mESC 行のマウス胚および派生のカルチャとカルチャのカルチャに関する詳細な手順を提供しています。このプロトコルは、特殊な機器を必要としないし、基本的な哺乳類の細胞の文化の専門知識を持つ任意の研究室で実施することができます。

このプロトコルに従い以上伸長形成の 95% の文化 (図 1 a) の最初の週後達成する必要があります。6 継代後 mESC の樹立は、60-80% の平均成功の実験的複製間で変数です。2i 添加ほど向上しません結果 129S2 のバック グラウンドを持つものなど、寛容なマウス系統を操作するときが、非寛容な系統を使用するときに必要です。
