Figure 5. Expression of fibronectin and
the ED-A fibronectin splice variant. Fibronectin is abundant in normal
conjunctiva (A) and in scarred filtering blebs (B). In
contrast, expression of the fibrogenic ED-A fibronectin splice variant
is restricted to perivascular areas in normal conjunctiva (A),
but expands throughout the tissue in scarred filtering blebs (B).
Specimens were double-stained for total fibronectin (green) and the
fibronectin isoform, ED-A (red). Scale bar represents 50 µm.
