Hierarchical clustering of tissues and miRNAs using Pearson correlation. Heatmap was constructed based on the relative cloning frequencies of miRNAs. Only those miRNAs occuring at least 20 times in all libraries are shown. Green and red indicate low frequency or high frequency miRNA cloned in the library, respectively.
