live imaging of glial cell migration in the drosophila eye imaginal disc

脊椎动物和无脊椎动物的生物的神经胶质细胞迁移到最终目标地区，以ensheath，并支持相关的神经元。虽然最近已经取得了进展来形容发展蛹翼（1），研究神经胶质细胞的实时迁移<em&gt;果蝇</em&gt;胶质细胞迁移，通常涉及固定组织的考试。生活的游动细胞的微观分析提供了在整个迁徙过程中，包括确定率和生长方向的变化细胞行为能力的考查。配合使用基因工具，实时成像可以被用来确定在发展过程中特定基因的更精确的角色。以往的工作由Silies<em&gt;等。</em&gt;（2）描述来自光秆，一个发展中国家的眼睛和大脑的结构连接的神经胶质细胞迁移，进入眼内固定的组织成虫光盘。在这里，我们研究神经胶质细胞的实时迁移到一个协议大纲<em&gt;果蝇</em&gt;眼成虫光盘。我们采取了一个果蝇线的优势，遵循在野生型和突变体动物的神经胶质细胞的进展，对发展中的神经胶质细胞的GFP。
