Gastrulation is the process by which the germ layers become positioned in an embryo. C. elegans gastrulation serves as a model for studying the molecular mechanisms of diverse cellular and developmental phenomena, including morphogenesis, cell polarization, cell-cell signaling, actomyosin contraction and cell-cell adhesion. One distinct advantage of studying these phenomena in C. elegans is that genetic tools can be combined with high resolution live cell imaging and direct manipulations of the cells involved. Here we review what is known to date about the cellular and molecular mechanisms that function in C. elegans gastrulation.
原肠胚形成是胚层在胚胎中定位的过程。秀丽隐杆线虫的原肠胚形成可作为研究多种细胞和发育现象分子机制的模型,这些现象包括形态发生、细胞极化、细胞间信号传导、肌动球蛋白收缩和细胞间黏附。在秀丽隐杆线虫中研究这些现象的一个显著优势是,遗传工具可与高分辨率活细胞成像以及对相关细胞的直接操作相结合。在此,我们综述了目前已知的在秀丽隐杆线虫原肠胚形成中起作用的细胞和分子机制。
