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. (A-D) Courtesy of Will Wood; (E) courtesy of Katie Woolley.
