Fig. 1From: Systems biology evaluation of cell-free amniotic fluid transcriptome of term and preterm infants to detect fetal maturitya Transcriptome analysis of RNAs isolated from AF at different gestational stages. RNAs isolated from 16 AF samples (4 Prenatal: 18-24 weeks, 6 Late Preterm: 34–36 weeks, 6 Term:39–40 weeks) were subjected to the AF transcriptome analysis. b Principal component analysis (PCA) of the top 3 identified components of RNA-seq samples showing the primary separation of samples by gestational ages. Prenatal (Green), Late Preterm (Blue) and Term (Red). c Heatmap produced by hierarchical clustering of genes and samples, showing the identification of differentially expressed genes in prenatal vs later preterm vs term AF samplesBack to article page
