chick ex ovo culture and ex ovo cam assay: how it really works

在繁殖初期的鸡蛋之间在体外和体内系统，并提供了血管的测试环境，不仅要研究血管生成，但更要研究肿瘤的发生。后的鸡胚绒毛尿囊膜（CAM）的发展，其血管网络可以轻松地访问，操纵和观察，因此对血管生成的实验提供了一个最佳设置。由于淋巴系统没有完全开发的后期阶段，直到孵化，鸡胚作为一个能够维持无特定物种的限制嫁接的组织和细胞的自然免疫缺陷的主机。除了培育发展异体和异种移植，CAM血管网络提供了一个独特的支持性环境对肿瘤细胞的血管内，传播和血管逮捕和被逮捕细胞渗出，形成微转移灶的一个仓库里。 实验目的，在最近期的研究CAM暴露切割通过蛋壳的一个窗口，并进行了实验在 OVO无障碍CAM和效果的观察和照片文件的可能性，造成很大的局限性。当鸡胚无壳培养使用1-4，提供了无实验细节，如果在所有出版，这些文化的存活率低。我们精制的鸡胚前OVO文化的方法显着引进的鸡蛋含量的合理控制挤压。这些当然OVO文化，加强无障碍CAM和鸡胚，使容易在体内影响的文件，并促进胚胎的实验操作。这使得大量的科学问题进行了成功的应用：（1）作为改善血管生成的实验5,6，（2）实验设立便利注射在鸡胚眼7-9的玻璃体，（3）作为一个测试环境中传播和血管内的分散维持移植成功和肢芽鸡和小鼠13以及文化作为一种改进系统 ​​肿瘤细胞从细胞接种于CAM 10-12线，（4（5）嫁接，繁殖，重新嫁接坚实的原发肿瘤组织活检获得表面上的CAM 14）为。 在这个视频文章中，我们描述了建立一个精致的小鸡前OVO文化和CAM与存活率的检测，50％以上。除了 ​​我们提供了一个一步一步前OVO文化的科学应用的大量成功应用的示范。 丹尼尔Dohle，苏珊D.婆娑，和塞巴斯蒂安Gustmann同等贡献这项研究。
