Fig. 5From: DNA methylation profiling of acute chorioamnionitis-associated placentas and fetal membranes: insights into epigenetic variation in spontaneous preterm birthsSample clustering based on array-wide neutrophil-specific CpG sites. Euclidean clustering of our chorionic villi DNA methylation data (n = 44 samples) using 2069 neutrophil-specific CpG sites largely separated aCA cases from the non-aCA cases. Asterisk indicates stable and significantly different clusters as determined by pvclust and sigclust2 packagesBack to article page
