dendra2 photoswitching through the mammary imaging window

在过去的十年，活体显微镜的分辨率在单细胞在小鼠和大鼠乳腺肿瘤<sup&gt; 1-4</sup&gt;成如肿瘤细胞迁移，侵袭和血管内的转移行为的机制导致了重要的见解<sup&gt; 5，6</sup&gt;，血管生成<sup&gt; 3</sup&gt;和免疫细胞的反应<sup&gt; 7-9</sup&gt;。最近，我们报道了多个活体成像会议的一种技术活老鼠形象原位乳腺癌<sup&gt; 10</sup&gt;。对于这一点，我们已经开发出乳腺影像窗口（MIW）和优化的成像参数为Dendra2<sup&gt; 11</sup&gt; photoswitching和成像<em&gt;在体内</em&gt;。在这里，我们描述MIW，插入肿瘤成像的Dendra2标记的肿瘤细胞，使用一个定制的成像盒的顶部MIW制造业的协议。该协议可用于不同的微环境在肿瘤中的肿瘤细胞的转移行为形象和长期的血管，肿瘤细胞与宿主细胞的长期成像。
