Fig. 2. Imaging wound re-epithelialisation in Drosophila embryos and zebrafish larvae. (A-D) Images taken at 30-minute intervals from a movie of a laser wound (broken lines) made to the ventral epithelial surface of a Drosophila embryo expressing -catenin-GFP. Cell shape changes and rearrangements of neighbour:neighbour relationships are apparent, but no cell division occurs during the brief repair period. (E) A scanning electron micrograph view of a similar wound in a zebrafish larva, showing how contraction of the leading edge cells causes the wound margin to ‘scrunch up’ as it is drawn forwards by the action of the purse-string.
