Levels of placenta-derived mRNA in maternal plasma in normal pregnancy. (A) Box plot of hPL mRNA in maternal plasma and protein levels in maternal serum at various stages of gestation. (B) Box plot of βhCG mRNA in maternal plasma and hCG protein levels in maternal serum at various stages of gestation. The lines inside the boxes denote the medians. The boxes mark the interval between the 25th and 75th percentiles. The whiskers denote the interval between the 10th and 90th percentiles. The filled circles mark the data points outside the 10th and 90th percentiles. (C) Correlation between hPL mRNA in maternal plasma and protein levels in maternal serum. (D) Correlation between βhCG mRNA in maternal plasma and protein levels (IU, international units) in maternal serum.
