Fig. 3From: Systems biology evaluation of cell-free amniotic fluid transcriptome of term and preterm infants to detect fetal maturityDynamic change of expression patterns of genes regulating important pathways/processes in AF samples. Genes related with (a) surfactant physiology and (b) VEGF signaling were induced with increasing gestational ages while genes involved in (c) Hippo signaling and (d) Wnt Signaling had significantly suppressed expression with increasing gestational ages. Prenatal samples are noted in Green, Late Preterm in Red, and Term in BlueBack to article page
