Analysis of Differential miRNA Expression in Primary Tumor and Stroma of Colorectal Cancer Patients

Figure 2

Bootstrap clustering analysis on tumor and stromal samples on the 26 differentially expressed microRNAs. Each row represents a single microRNA, and each column represents a sample (T, tumor; S, stroma). Red colors on the heat map indicate expression levels higher than the median, while green colors show expression levels lower than the median. The red branches on the dendrogram indicate an approximately unbiased (AU) confidence greater than 95%.
