Effect of hyperglycemia on EPCs function and regenerative ability حسب Hendawi, Hadeel Khalil

"…For that, we studied BOECs viability, response to shear stress, angiogenesis ability, and barrier function under normoglycemic (5.5mM) and hyperglycemic (25mM) conditions. The results have shown significant effects of chronic hyperglycemic conditions on cell proliferation (n=3, p<0.05), and migration (n=3, p<0.05) which were decreased when compared to control. …"
