Figure 12.

The extent of wound closure in the experiments in Figure 11 was quantitated. Wounds were photographed 0 and 18 h after wounding. For each trial 40 measurements across the wound at distances at least 100 μm apart were made 18 h after wounding. These measurements were used to determine the average wound closure (average width of the wound at 0 h minus average width of the wound at 18 h). This is presented as a percentage of the average width of the wound at 0 h.
