Table 1. Fibroblast growth factor 2 loss affects proliferation of lens epithelial cells

The incidence of BrdU-positive lens epithelial cells in each specimen as determined by the method described in the text. The number of animals at each healing interval is described in Methods. In the Healing interval column, "+ mice" refers to fgf2^+/+ mice and "- mice" refers to fgf2^-/- mice. Asterisk indicates a significant difference between fgf2^+/+ mice and fgf2^-/- mice (single asterisk, p<0.05; double asterisk, p<0.01).
