All subjects provided written informed consent approved by the Institutional Review Boards at Women and Infants Hospital and Dartmouth College. For each subject and within 2 hours of delivery, samples of placenta parenchyma (totaling approximately 8–10 g of tissue) were excised. All samples were taken from the fetal side of the placenta, 2 cm from the umbilical cord insertion site, free of maternal decidua. RNA was collected from placenta using Qiagen RNeasy Mini Kit, and samples with a RNA Integrity Number above 5.0 were kept for sequencing (n = 19). Paired end libraries were prepared and sequenced on an Illumina HiSeq2000 at the University of Miami Miller School of Medicine Center for Genome Technology following their standard protocol. Across samples, an average of 42.3 million paired reads with an average quality of 34.5 were obtained. Sequences from each sample were aligned to the human genome (hg19) using TopHat2 default parameters, with an average of 27.1 million reads (~64% mapping rate) mapping successfully.

All subjects provided written informed consent approved by the Institutional Review Boards at Women and Infants Hospital and Dartmouth College. For each subject and within 2 hours of delivery, samples of placenta parenchyma (totaling approximately 8–10 g of tissue) were excised. All samples were taken from the fetal side of the placenta, 2 cm from the umbilical cord insertion site, free of maternal decidua. RNA was collected from placenta using Qiagen RNeasy Mini Kit, and samples with a RNA Integrity Number above 5.0 were kept for sequencing (n = 19). Paired end libraries were prepared and sequenced on an Illumina HiSeq2000 at the University of Miami Miller School of Medicine Center for Genome Technology following their standard protocol.
