Figure 5. Expression pattern of transforming growth factor β1 (TGFβ1) in injured lenses. At days 2 (A) and 5 (C), immunoreactivity for TGFβ1 was detected in the lens epithelial cells adjacent to the site of capsular injury in a wild-type mouse. Although no such immunoreactivity was observed in the multicellular layer at day 2 in an injured tenascin-C null lens, it was readily detected at day 10 (D). Arrows, edge of the injured anterior capsule. AC, anterior capsule; Bar, 10 μm.
