Insets from (C) revealing the propagation of fissures between basal cells over time after wounding. Blue arrowheads indicate the appearance of dark puncta at tricellular junctions that precedes full fissuring. Yellow arrowheads indicate large dark puncta that appear within cells after fissuring has occurred. Magenta arrowheads highlight the irregular, beads-on-a-string morphology that fissures develop over time. Insets (Di)–(Diii) follow specific cells over time as they migrate to the wound. The cell followed in inset (Diii) migrates the most, consistent with its position nearest the wound.
