Skull vault formation in individual WT AB Fish

An individual fish was imaged successively from 12-23 dpf by confocal microscopy, during the period of induction and growth of the frontal and parietal bones. The fish was transgenic for col1a1a:gfp, marking chondrocytes, and for sp7:mcherry, marking osteoblasts.研究人员在额骨与顶骨的诱导及生长阶段，采用激光共聚焦显微镜（confocal microscopy）对单条鱼进行了连续成像，成像时间覆盖受精后12至23日龄（days post fertilization, dpf）。该鱼为双转基因个体，分别携带有用于标记软骨细胞（chondrocytes）的col1a1a:gfp转基因，以及用于标记成骨细胞（osteoblasts）的sp7:mcherry转基因。
