This video shows the dynamics of the apical cell surface of individual cells of the enveloping layer in a killifish embryo. The fluorescent actin is seen to polymerize and depolymerize in cyclic waves that extend and retract these surface protrusions. Two neighboring cells from a continuous epithelium are expressing the fluorescent GFP-actin. The expression of this inserted gene is mosaic, with some cells expressing, and others not.

本视频展示了鲇鱼胚胎中包被层单个细胞顶端细胞膜的动态变化。荧光标记的肌动蛋白可见于形成周期性波动的聚合和解聚过程，这些波动导致表面突起的伸展与收缩。来自连续上皮层的两个邻近细胞表达荧光标记的GFP-肌动蛋白。插入基因的表达呈现镶嵌状，部分细胞表达，而另一些细胞则不表达。
