Koh et al. performed a longitudinal study on pregnant women that analyzed their combined cell-free RNA transcriptomes across all three trimesters of pregnancy and after delivery. Plasma samples were collected from 4 non-pregnant subjects (2 men and 2 women), as well as from 11 pregnant women who contributed samples at the first, second, and third trimesters and postpartum.
