灌注的整体器官脱细胞最近获得了为手段，以创建特定的细胞外基质支架，组织工程领域的兴趣，同时很大程度上保留了原生架构的支架。至目前为止，这种方法已经被使用在各种不同的器官系统，包括心脏，肺，肝1-5。没有一个方便的血管网组织往前脱细胞方法都依赖于长时间暴露的组织的解决方案的清洁剂，酸或酶处理，作为一个装置，以除去细胞和核的组件，从周围的细胞外环境6-8。然而，这些方法的铰链的有效性的解决方案的能力后，通过扩散渗透到组织。相比之下，通过自然器官灌注血管系统有效地减少了扩散距离，便利的交通decellularizati代理商进入组织和细胞成分的组织。在这里，我们描述一个的方法完全decellularize通过一个完整的猪心脏冠状动脉逆行灌注。该协议得到充分脱细胞的心肌细胞外基质（ECM）的支架的三维结构体的心脏完好无损。我们的方法，使用了一系列的耦合与高渗和低渗漂洗，以帮助在裂解和去除细胞的酶，洗涤剂，和酸。所使用的协议胰蛋白酶溶液分离后跟的Triton X-100和脱氧胆酸钠的解决方案，以帮助除去多孔材料中的基质细胞。所描述的协议也使用大于2升/分钟的长时间的灌注速度。高流速，加上与解决方案的变化允许运输的代理到组织没有细胞碎片污染和确保有效地冲洗该组织。从National Instruments，简称NI所描述的方法删除了所有核材料维生素E猪心脏组织，创建特定于站点的心脏ECM支架，可用于各种各样的应用。

自然对整个猪心脱细胞的效果的不同而不同的大小的差异，压力，和船只安排。因此，确切的成分派生的细胞外基质支架是不一样的，从心脏到心脏。所描述的协议的完成将产生一个心脏出现白色或半透明状，表明细胞物质的损失。然而，它已被广泛接受的组织可以被视为“脱细胞”的基础上，结合数更多的量化参数8。一个成功的脱细胞协议会产生一个矩阵，每毫克的组织（图6）<...
