Fig. 2From: Microarray analysis reveals a potential role of LncRNAs expression in cardiac cell proliferationDifferential expression of lncRNAs between fetal and adult heart. Hierarchical clustering analysis shows differential expression of LncRNAs (FC ≥ 5) using a heat map (a). ‘Red’ indicates higher expression, whereas ‘blue’ indicates lower expression. The bar code represents the color scale of log2 transformed values. The scatterplot (b) is a visualization used for assessing the variation between the chips. The X and Y axes in the scatterplot represent the normalized signal values of each group (log2 scaled). The green lines represent FC (FC = 2.0) linesBack to article page
