哺乳類の器官形成のほとんどの面の研究は、生体外でシステムによって促進されています。2 つの主な方法は今前庭感覚的な器官の培養用: 浮遊1と付着性2準備。両方のメソッドは、有毛細胞の脆弱性3と再生1,4 の生体外の調査を許可します。さらに、ノッチ5,6, Wnt7、8、上皮成長因子受容体 (EGFR)9,10内耳のカスケードをシグナル伝達の発達の役割があります。確立されて、一部、感覚上皮の体外培養を使用しています。しかし、細胞の成長と分化制御、細胞間の連絡先など物理的、機械的な手がかりにも介してモルフォゲン シグナル伝達細胞外マトリックスの剛性と機械的伸張または収縮だけではなく。このような機械的刺激の役割は、発展途上の内耳の生体内で調査するは困難です。また、既存の浮遊・付着性文化メソッドはこのような研究の培養に適してではありません。ここで述べるコラーゲンの三次元培養のため私はゲルのさまざまな剛性。このメソッドは主前庭と蝸牛の感覚器官の生体内でアーキテクチャを保持され、により、増殖・分化11機械力の影響の検討。
力学的刺激は、シグナリング経路12,13,14,15、カバなどの下流の分子イベントをアクティブにする知られているので機械的刺激を組み合わせることができることが重要です。生化学的および遺伝的操作。ここで説明した培養法は、ウイルスを介する遺伝子導入を可能し、内耳開発11時両方の機械的および分子伝達を研究するためすることができます。

three-dimensional organotypic cultures of vestibular and auditory sensory organs

内耳の感覚器官は、実験操作と光学観測にその到達不能のための哺乳類の研究に挑戦しています。また、既存の培養技術は生化学的摂動ことは、これらのメソッドが、内耳感覚的な器官の開発中に機械的な力と組織剛性の効果を検討するための手段を提供しません。ここでそのままマウス卵形嚢とこれらの制限を克服して蝸牛の三次元培養法について述べる。ここで説明した三次元マトリックス剛性の調整法は、弾性組織の成長に反対の操作を許可します。このメソッドは、内耳開発中に機械的な力の役割を研究するため使用できます。さらに、文化は、利得と損失-の機能実験に使用することができますウイルス媒介性遺伝子配信を許可します。この培養法は、生来の有毛細胞を保持され、支持細胞し前庭と聴覚の感覚器官の伝統的な二次元文化を代替する可能性のある優れた役割を果たします。

胚の耳から前庭と聴覚の感覚器官はマイク低剛性萌芽期の条件11を模倣したゲル 40 Pa コラーゲン培養、比較的普通の三次元構造 (図 1) を保ち、有毛細胞を維持し、支持細胞 (図 2および図 3)。30% 以上減少する細胞密度をサポート (スチューデントのt検定: n = 4、 p < 0.004) ?...
