MiR-21, PTEN, and VEGF expressions in model rats. (A) Quantitative levels of miR-21 in model rats among different groups (control, model, BMSC, miR-21 mimics, and miR-21 inhibitors). (B) Western blot analysis of PTEN and VEGF in cardiac tissues of rats with GAPDH as internal control. (C, D) Quantitative protein level of PTEN (C) and VEGF (D) in model rats. Data are presented as mean ±SD. * P<0.05 versus control group, #
P<0.05 versus NC group, @
P<0.05 versus BMSC group, &
P<0.05 versus miR-21 mimics group.
