Similarity of global gene expression and expressed mutations between tumors and organoid cultures. a Heatmap showing the Pearson correlation coefficient (color key) between tumors (rows) and organoids (columns) based on the normalized counts of tumor- and organoid-specific genes. Dendrograms show the hierarchical clustering based on the complete method and Euclidean pair-wise distance. In some cases, multiple passages from the same organoid culture are included. b Mutations as in Fig. 2 colored by whether the mutated allele, the reference allele, or no expression were detected by RNA-seq
