CIL:20066

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Cleavage period at the 1.5 hour 16 cell stage. The animal pole is to the top for the early stages, and anterior is to the top later, except for the two animal polar (AP) views shown below their side view counterparts for germ-ring and shield gastrulas. Face views are shown during cleavage and blastula stages. After shield stage, the views are of the embryo's left side, but before the shield arises one cannot reliably ascertain which side is which. Pigmentation is omitted. Arrowheads indicate the early appearance of some key diagnostic features at the following stages: 1 k-cell: YSL nuclei. Dome: the doming yolk syncytium. Germ ring: germ ring. Shield: embryonic shield. 75%-epiboly: Brachet's cleft. 90%-epiboly: blastoderm margin closing over the yolk plug. Bud: polster. 3-somite: third somite. 6-somite: eye primordium (upper arrow), Kupffer's vesicle (lower). 10-somite: otic placode. 21-somite: lens primordium. Prim-6: primordium of the posterior lateral line (on the dorsal side), hatching gland (on the yolk ball). Prim-16: heart. High-pec: pectoral fin bud. Composite image CIL: 20098 is a low resolution image with a scale bar = 250 microns that shows the entire set of image. Images correspond to Fig 1 of Developmental Dynamics 203:253-310 (1995).

本数据集收录了选定发育阶段斑马鱼胚胎的明视描记法（Camera lucida）手绘草图。本示例图像取自卵裂期的1.5小时16细胞阶段。早期图像以动物极为上方，后续阶段则以前端为图像上方；仅胚环期与盾期原肠胚的动物极（AP）视角被置于其对应侧视图的下方。卵裂期与囊胚期采用正面观。盾期之后的图像均为胚胎左侧视角，但盾期形成前无法可靠区分左右侧。图像中省略了色素沉着结构。箭头标注了各阶段关键诊断特征的早期出现位置，具体如下：1千细胞期：卵黄合胞体层（yolk syncytial layer, YSL）细胞核；圆顶期：隆起的卵黄合胞体；胚环期：胚环；盾期：胚盾；75%外包期：布拉谢裂隙（Brachet's cleft）；90%外包期：胚层边缘闭合于卵黄栓上方；芽基期：前端隆起（polster）；3体节期：第三体节；6体节期：眼原基（上箭头）、库普弗囊泡（Kupffer's vesicle，下箭头）；10体节期：耳板；21体节期：晶状体原基；Prim-6期：后侧线原基（背侧）、孵化腺（卵黄球表面）；Prim-16期：心脏；高鳍期：胸鳍芽。编号为CIL:20098的合成图像为低分辨率版本，附带比例尺（250微米），完整展示了本数据集的全部图像。本数据集图像对应《发育动力学》（Developmental Dynamics）203卷第253-310页（1995年）的图1。本文本内容经约翰威立出版公司（John Wiley & Sons, Inc.）授权转载，版权归1995年WILEY-LISS, INC.所有。
