Endogenous EFs controlled the frequency of cell division. In all groups, cells tended to divide more at 400 and 600 μm away from the leading edge, rather than in the first 200 μm from the wound. PGE₂ and aminophylline significantly increased cell divisions at 400 and 600 μm, but had no effect at 200 μm, or in the limbus. Ouabain significantly decreased cell divisions in the first 200 μm, but had no effect in other areas. Neomycin significantly increased cell divisions at 600 μm and in the limbus, but had no effect at 200 and 400 μm. *, P < 0.05.
