Clearance of fetus-derived mRNA from maternal plasma after delivery. (A and B) Maternal plasma hPL mRNA levels (A) and maternal plasma GAPDH mRNA levels (B) before delivery and 24 h after delivery. The results of eight plasma samples are shown, and each line represents one plasma sample obtained from one subject. (C and D) Maternal plasma hPL mRNA levels (C) and maternal plasma GAPDH mRNA levels (D) before delivery and 2 h after delivery. The results of 13 plasma samples are shown, and each line represents one plasma sample obtained from one subject.
