(A) Expression of Il22, Il10rb, Il22ra1, and Il22ra2 in the fetal membranes of mice intra-amniotically injected with Ureaplasma parvum (n = 8) or SP4 broth (n = 8). (B) Expression of Il22, Il10rb, Il22ra1, and Il22ra2 in the placentas of mice intra-amniotically injected with Ureaplasma parvum (n = 8) or SP4 broth (n = 8). Heatmap representations showing inflammatory gene expression in the (C) lung and (D) intestine of fetuses of mice intra-amniotically injected with Ureaplasma parvum (n = 8) or SP4 broth (n = 8). Stars indicate significant differentially expressed genes. (E) Expression of Nfkb2, Il1a, Il1b, Il6, Tnf, Il12b (Il12p40), Ccl2, Ccl3, Cxcl1, Cxcl5, Cxcl10, Il10rb, Il23a, Il27, and Lrg1 in the lung of fetuses of mice intra-amniotically injected with Ureaplasma parvum (n = 8) or SP4 broth (n = 8). (F) Expression of Nfkb2, Il22ra1, and Lrg1 in the intestine of fetuses of mice intra-amniotically injected with Ureaplasma parvum (n = 8) or SP4 broth (n = 8). P-values were determined using Mann-Whitney U-tests.
