Genes uniquely expressed in different layers of villus sections. sam algorithm was used to select 230 genes whose expression varied significantly among fetal, middle, and maternal sections. These genes, which were selected with a delta of 0.2 to get a maximum false-discovery rate (q-value) of 0.6, were then used to hierarchically cluster the samples to visualize the expression profile within the villus parenchyma. The three gene clusters were assigned names (shown on the left) based on the sections that show a relatively greater expression of the genes (right). Genes whose names are shown in red are potentially associated with a hypertensive pregnancy disorder, PE, and are expressed mostly in maternal and/or fetal sections. The visualization format is the same as Fig. 3.
