Placental ACE2 protein levels are increased in PTB with/without chorioamnionitis (ChA) as compared to term. Protein lysates of placentas from PTB, ChA, ELCS and SVD deliveries were assessed for level of ACE2 protein by western blotting. (A) Representative western blot images and (B) densitometric analysis of ACE2 protein level, normalized by β-actin (loading control for protein), n = 6/group. Statistical differences were tested by Tukey’s multiple comparisons test. Data are presented as mean ± SEM. Different letters indicate a difference between groups of p < 0.05.
