isolation and genetic manipulation of adult cardiac myocytes for confocal imaging

成人の心臓から単離された心筋細胞は広くどこかにモデル片側の胚および新生児の筋細胞と他の上で働く心臓の間に半分の方法として受け入れられています。従って、心筋細胞は心臓細胞生理および病態生理のため、医薬品の調査のためだけでなく、トランスジェニック動物モデルを検証するための良いモデルとなる。ここでは、心臓から細胞を単離する方法を説明します。さらに我々は心筋細胞で遺伝子操作がトランスジェニック動物を飼育することなく実行できる方法を示します：これは長期の培養（1週間）とアデノウイルス遺伝子導入を組み合わせたものです。後者は、ウイルスの構造から細胞の形質導入に記述されています。それは、RNAiを用いて、例えば、発現とダウンレギュレーションを介して遺伝的に符号化されたバイオセンサー（GEBs）、蛍光融合タンパク質を発現させるためだけでなく、蛋白質に使用することができます。ここでは、細胞内構造（ゴルジ体）を染色する融合タンパク質を発現させるための例を提供しています。このようなタンパク質の発現は、細胞内構造の3次元再構築のためのz -スタックの共焦点イメージングで可視化することができる。プロトコルは、細胞培養、分子生物学と生物物理学の最先端を構成し、従って細胞の心臓病の新たな地平を探索するためのアプローチを提供します。
