Figure 4. Increased cell proliferation at earlier responses to wounding in K14-cre^+/−/NICD⁺ cornea. A: Quantification of BrdU positive cells in the corneal epithelium of the WT and K14-cre^+/−/NICD⁺ mice at different time points after wounding. The average number of the BrdU positive cells per 1 mm length parallel to the cornea surface was calculated from the counts on three random sections of each four wounded eyes. B: Quantification of BrdU positive cells in the limbal epithelium of the WT and K14-cre^+/−/NICD⁺ mice at different time points after wounding. Each bar represents the average number of the BrdU⁺ cells per 1 mm limbal epithelium±SD. The number was calculated from the counts on three random sections from each four wounded eyes for each experimental group. Two-tail t-test: **p<0.005 and *p<0.05. n=12.
