Figure 2From: Effect of vildagliptin, a dipeptidyl peptidase 4 inhibitor, on cardiac hypertrophy induced by chronic beta-adrenergic stimulation in ratsEffect of vildagliptin on cardiomyocyte size in isoproterenol-treated rats. Hematoxylin and eosin staining of hearts in the vehicle, ISO, and ISO-VL treatment groups. The widths of 30 individual cardiomyocytes in rat were measured across a line bisecting the nucleus. Scale bar = 100 μm. Bar graph shows the cardiomyocyte width. Values represent the mean ± SE. n = 6 each. NS = not significant.Back to article page
