Fig 5
Endothelin receptor B (ETB) immunofluorescence in cross-sectional proliferative diabetic retinopathy and idiopathic epiretinal membranes.
Confocal images of diabetic ERMs (top) show variable ETB (red) staining among tissue samples. Confocal images of idiopathic ERMs (bottom) also showed variable ETB immunofluorescence. Nuclei are labeled with SYTOX Green nuclear stain (green). Patient numbers are indicated in the upper-right corners. Scale bars: 50 μm.
