CIL:37404

A 2.75 hour Zebrafish embryo; the same embryo as in CIL 37403 --later in blastoderm development. The video shows dynamics in a perisagital section of the embryo. The sequence shows blastomeres dividing asynchronously. The surface cells begin to take on epithelial characteristics. A distinct yolk syncytial layer emerges. At each prophase, rapid movements of yolk platelets occur within the yolk. This video made available by Mark Cooper thru Zebrafish - The Living Laboratory. The videos in this group can also be found in the Developmental Landmarks page of the Fishscope web site.

本数据集包含一段时长2.75小时的斑马鱼胚胎（Zebrafish embryo）影像，该样本与CIL 37403中的胚胎完全一致，处于囊胚层（blastoderm）发育后期。视频展示了该胚胎矢状旁切面的动态变化过程：序列中可见卵裂球（blastomeres）发生异步分裂，胚胎表面细胞开始呈现上皮细胞特性，清晰的卵黄合胞体层（yolk syncytial layer）逐渐形成；在每个分裂前期，卵黄内部的卵黄小板（yolk platelets）会出现快速运动。本视频由Mark Cooper通过Zebrafish - The Living Laboratory平台发布，本组视频亦可在Fishscope网站的发育里程碑（Developmental Landmarks）页面获取。
