Figure 1

Overall gene expression profile analysis of the placentas from pre-eclamptic and normotensive pregnancies with or without FGR. A. Correlation coefficient of the microarray data between each sample pair. Red indicates 1.0, whereas black indicates less than 0.9. PE, pre-eclampsia. B. Clustering analysis using the NMF method. K = 2 (upper panel) or K = 3 (lower panel) indicate the number of modeled subclasses. Red indicates a high, whereas blue indicates a low correlation coefficient. The cophenetic correlation coefficients were measured as follows: 0.9313 (K = 2), 0.8350 (K = 3), 0.7915 (K = 4), and 0.7838 (K = 5).
