Fig. 6From: In vivo imaging of epithelial wound healing in the cnidarian Clytia hemisphaerica demonstrates early evolution of purse string and cell crawling closure mechanismsNon-muscle myosin II is essential for Phase 2 contraction. In the presence of blebbistatin, lamellipodia form (arrowheads) and close the wound gap, and zippering occurs between cells to create a seam (arrows). However, no apparent contraction follows the zippering even 10 min later (see Additional file 9 for greater detail). Experiment was replicated 3 times. Scale bar = 50 μmBack to article page
