Leonard D'Amico (2011) CIL:11814, Danio rerio, yolk syncytial layer cell. CIL. Dataset

Epiboly movements of yolk syncytial layer (YSL) nuclei during gastrulation from a dorsal-vegetal pole view. A marginal band of nuclei moves toward the vegetal pole during epiboly, while some nuclei move out of the marginal zone to populate the I-YSL under the blastoderm.

胚胎囊胚层（YSL）核在囊胚形成过程中的表被运动，从背-胚极视角观察。在表被过程中，一环形核带向胚极移动，同时部分核脱离边缘区域，以填充位于胚盘下方的I-YSL。该视频由Mark Cooper通过斑马鱼-活体实验室提供。
