Figure 3. Bromo-deoxyuridine labeled cells in the injured lens

Bromo-deoxyuridine (BrdU)-labeled cells in the equatorial region (A and B) and at the site of capsular break (C and D) in the injured lens of a fgf2^+/+ (A and C) or fgf2^-/- (B and D) mouse at day 5 post-treatment. BrdU-labeled cells (black arrows) are seen in the lens of a fgf2^+/+ mouse, but not in that of an fgf2^-/- mouse. Open arrows indicate capsular breaks. The bars represent 50 μm.
