CIL:20079

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Gastrula period at the 5.7 hour germ ring 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).

本数据集为采用投影描绘器（Camera lucida）绘制的斑马鱼胚胎特定发育阶段草图。本图处于原肠胚形成期（Gastrula period）的5.7小时胚环（germ ring）阶段。早期阶段以动物极（animal pole）朝上，后期则以前端（anterior）朝上；仅胚环和原盾原肠胚的动物极视图（animal polar view, AP视图）置于其侧视图下方，为上述规则的例外情况。卵裂期与囊胚期展示胚胎正面视图。原盾期（shield stage）之后，所有视图均为胚胎左侧视角，但在原盾结构形成前，无法可靠区分左右侧。图中省略了色素沉着细节。箭头指示以下各发育阶段关键特征的早期出现情况：1细胞期（1 k-cell）：卵黄合胞体层（Yolk Syncytial Layer, YSL）细胞核；圆顶期（Dome）：隆起的卵黄合胞体；胚环期（Germ ring）：胚环；原盾期（Shield）：胚胎原盾（embryonic shield）；75%外包期（75%-epiboly）：布拉谢裂隙（Brachet's cleft）；90%外包期（90%-epiboly）：胚盘边缘闭合于卵黄栓上方；芽基期（Bud）：脊索前板隆起（polster）；3体节期（3-somite）：第3体节；6体节期（6-somite）：眼原基（上方箭头）与库普弗囊泡（Kupffer's vesicle，下方箭头）；10体节期（10-somite）：耳基板（otic placode）；21体节期（21-somite）：晶状体原基（lens primordium）；原基6期（Prim-6）：后侧线原基（位于背侧）与孵化腺（位于卵黄球上）；原基16期（Prim-16）：心脏；高鳍期（High-pec）：胸鳍芽（pectoral fin bud）。组合图像CIL:20098为低分辨率图像，附带250微米比例尺，完整展示了本图像集合。本系列图像对应《Developmental Dynamics》203卷：253-310页（1995年）中的图1。本文献经John Wiley & Sons公司授权转载，版权所有©1995 WILEY-LISS, INC.
