Overexpressed miR-18b-3p ameliorates pathological change and suppresses apoptotic cells of placenta tissues in PE rats. a HE staining was utilized to test pathological features of placenta tissues. b TUNEL staining was implemented to determine apoptotic cells of placenta tissues in PE rats. c Cell apoptosis rate was detected by TUNEL staining. n = 10, *p < 0.05 versus the normal group. ^p < 0.05 versus the miR-NC group. ^@p < 0.05 versus the miR-18b-3p antagomir group. ^&p < 0.05 versus the si-NC group. Measurement data were depicted as mean ± standard deviation, and comparisons among multiple groups were assessed by one-way ANOVA followed by Tukey’s test
