Neural tube formation in a zebrafish embryo. Neural tube is the precursor of our brain and spinal cord. This movie uses mosaic labeling for the neural progenitors allowing them to be followed as well as their morphology and projections analyzed. Transgenic reporters are used to analyze the gene expression changes in the cells.
Annotations: Red: ptch2:kaede signal, Green: cell membrane signal. Movie is a combination of top view (bottom) and cross-sectional view (Top) 3D maximum rendering of the 3-channel timelapse dataset. The cross-sectional view highlights the patterning events of the dorsal-ventral axis of the spinal cord. The temporal resolution between each frame is 6 minutes. Time annotation indcates hours post fertilization.
