Representative fluorescence images and quantification of TUNEL-positive HRMECs. TUNEL staining (green, A2-D2), DAPI staining (blue, A1-D1), and merged image of HRMECs with different treatments. Merged images are presented as A3-D3. Con-5.5, G25-G100: concentration of glucose (5.5, 25, 50, and 100 mmol/l, respectively). HRMECs: human retinal microvascular endothelial cells. Scale bar: 200 μm. ; .
