CIL:20094

Camera lucida sketches of the zebrafish embryo at selected stages. This image is from the Pharyngula period at the 42 hour high pec 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).

投影描绘器（Camera lucida）绘制的斑马鱼胚胎特定发育阶段素描图。该图取自42小时高鳍阶段的咽胚期（Pharyngula period）。早期胚胎以动物极（animal pole）朝上，后期则以前侧（anterior）朝上；仅胚环（germ ring）与盾期原肠胚（shield gastrula）的动物极（AP）视图置于其侧视图下方。卵裂期（cleavage stages）与囊胚期（blastula stages）的胚胎均以正面视图呈现。盾期之后的视图均为胚胎左侧面，而盾期形成前无法可靠区分左右两侧。本图未标注色素沉着情况。箭头标注了下述各阶段关键诊断特征的早期出现情况：1千细胞期：卵黄合胞体层（YSL）细胞核；圆顶期：隆起的卵黄合胞体；胚环期：胚环；盾期：胚胎盾；75%外包期：布拉谢裂隙（Brachet's cleft）；90%外包期：胚盘边缘闭合卵黄栓；芽基期：头部隆起（polster）；3体节期：第三体节；6体节期：眼原基（上方箭头）与库普弗囊（Kupffer's vesicle，下方箭头）；10体节期：耳板；21体节期：晶状体原基；原基6期（Prim-6）：后侧线原基（背侧）与孵化腺（卵黄球表面）；原基16期（Prim-16）：心脏；高鳍期：胸鳍芽。复合图像CIL:20098为低分辨率图像，配有比例尺250微米，完整展示了全部绘图集合。本图像对应《Developmental Dynamics》203卷第253-310页（1995年）中的图1。本材料经约翰威立出版公司（John Wiley & Sons, Inc.）授权转载，版权所有©1995 WILEY-LISS, INC.
