Figure 4. Expression pattern of fibronectin in injured lenses. At days 5 (A) and 10 (C), immunoreactivity for fibronectin was detected in the multicellular layer formed at the site of capsular injury in a wild-type mouse (B), whereas no such immunoreactivity was observed in the multicellular layer at day 5 in an injured tenascin-C null lens, although it was readily detected at day 10 (D). Arrows, edge of the injured anterior capsule. AC, anterior capsule; Bar, 10 μm.
