Effect of AT1R and AT2R antagonists on Ang II-mediated migration of MSCs. a Nondirectional migration ability of MSCs after stimulation with 100 nM Ang II following pretreatment with Losartan (5 μM) and/or PD-123319 (5 μM) examined with the scratch assay. Wound sites (areas cleared of cells in the center of the scratched area) were observed and photographed at 0 and 24 h (200×). b Quantitative results of wound healing. c Directional migration ability of MSCs after stimulation with 100 nM Ang II following pretreatment with Losartan (5 μM) and/or PD-123319 (5 μM) examined using the Transwell migration assay. Migrated cells on the bottom surfaces of the Transwell inserts were stained with crystal violet and observed under a microscope (200×). d Quantitative results of cell migration. Significant differences were found compared with the normal group (n = 3; *p < 0.05) and compared with the control group (n = 3; ^# p < 0.05). Ang II angiotensin II
