live imaging of drosophila melanogaster embryonic hemocyte migrations

许多研究解决细胞迁移<em&gt;在体外</em&gt;方法，是生物体本身，而有关生理环境。在这里，我们提出了一个协议的安装<em&gt;果蝇</em&gt;胚胎及随后的荧光标记血细胞实时成像，这个有机体的胚胎巨噬细胞。利用GAL4 - UAS系统<sup&gt; 1</sup&gt;我们的驱动器的多种荧光标记基因编码，在血细胞的标记，按照他们在整个胚胎发育疏散的表达。以下收集所需的发展阶段的胚胎，外层的绒毛膜被删除，胚胎，然后安装在卤烃油之间的疏水性，透气膜和实时成像的玻璃盖玻片。此外，如速度和方向性更高分辨率的成像，再加上使用的F -肌动蛋白和微管可以提供更详细的信息，关于这些细胞骨架的动态的荧光记者毛候鸟参数。
