Figure 3. Colocalization of TGF-β-RII and
the fibroblast marker prolyl-4-hydroxylase. Native conjunctiva (A)
and scarred filtering bleb specimens (B, C) were
double-stained for TGF-β-RII (green) and prolyl-4-hydroxylase (red). C
is a close-up of a portion of B as indicated by the frame.
Arrows point to a TGF-β-RII positive fibroblast, which are positive for
both TGF-β-RII and prolyl-4-hydroxylase. Scale bar represents 50 µm (A,B)
and 10 µm (C).
