During embryonic development, complex changes in cell behavior generate the final form of the tissues. Extension of cell protrusions have been described as an important component in this process. Cellular protrusions have been associated with generation of traction, intercellular communication or establishment of signaling gradients. Here, we describe and compare in detail from live imaging data the dynamics of protrusions in the surface ectoderm of chick and mouse embryos. In particular, we explore the differences between cells surrounding the lens placode and other regions of the head.

胚胎表面外胚层细胞突起的表征

在胚胎发育过程中，细胞行为的复杂变化产生了组织的最终形式。细胞突起的延伸已被描述为该过程中的重要组成部分。细胞突起与牵引力的产生、细胞间通讯或信号梯度的建立有关。在这里，我们从实时成像数据中详细描述和比较了鸡和小鼠胚胎表面外胚层中突起的动态。特别是，我们探讨了晶状体基板周围细胞与头部其他区域之间的差异。
