Analysis of the apoptosis of bone marrow mesenchymal stem cells from orofacial bone transfected with NC, miR-148b-3p mimics, NC inhibitor or miR-148b-3p inhibitor. Values are expressed as the mean ± standard deviation. ***P<0.001 vs. NC inhibitor; #P<0.05 vs. NC. PI, propidium iodide; FITC, fluorescein isothiocyanate; NC, negative control; miR, microRNA; miR-148b-3p I, miR-148b-3p inhibitor; Q, quadrant; UL, upper left; LR, lower right.
