miR-125b inhibit NS/PCs proliferation. Cell proliferation was evaluated by bromodeoxy uridine (BrdU) incorporation. Representative images of NS/PCs stained with Brdu (green) and Hoechst dye (blue) 72 h after transfection. After transfection, the NS/PCs were maintained in growth medium until they were fixed and stained. Images were acquired by a microscope using a 20 × objective lens. The percentage of BrdU-positive cells at 72 h after transfection is shown. Bars show mean ± SD. All experiments were repeated three times. * P < 0.05 vs. ctr, ** P < 0.01 vs. ctr.
