To predict the role of microRNAs within gene regulatory networks of maternal peripheral blood natural killer (pNK) cells during pregnancy, Ishida et al. performed comprehensive miRNA and gene expression profiling of maternal pNK cells using a combination of real-time PCR-based array and DNA microarray analyses. Samples were obtained from the same healthy pregnant females during the first (7–11 weeks) and third trimesters (36–38 weeks) of gestation.
