Figure 4From: High glucose-induced apoptosis in human coronary artery endothelial cells involves up-regulation of death receptorsRepresentative histograms of HCAECs expressing TNF-R1. Surface expression of TNF-R1 was analyzed by flow cytometry using FITC-labeled anti-human TNF-R1 antibody. Cells were treated with 16.7 mM glucose in the presence or absence of 0.3 nM TNF-α for 24 h. Similar results were obtained with two additional experiments.Back to article page
