Additional file 12: Movie 7. of In vivo imaging of epithelial wound healing in the cnidarian Clytia hemisphaerica demonstrates early evolution of purse string and cell crawling closure mechanisms
Lamellipodia-mediated closure of a wound of the same approximate size and shape as in Additional File 11, as shown in Fig. 7F–H. Note that after lamellipodia meet to close the gap, there is a contraction around the perimeter. When looking at a healing wound in this contracted state it is impossible to tell whether the wound originally closed through lamellipodia meeting (this movie) or a purse string drawing the cells forward (Additional file 11). Frames were taken every 12–13 s. The duration of the movie is 10 min. Scale bar = 50 μm. (MP4 5766 kb
