Comparison of transcriptomes between different tissue types. A Principal component analysis (PCA) plot of sample triplicates. PC1, principal component 1. PC2, Principal component 2. B Volcano plots for all sample comparisons. FPKM values were compared between two samples. Each volcano plot shows the distribution of fold change and Student’s t-test for all transcripts. Differentially expressed genes (DEGs) were identified with fold change > 2 or fold change < 0.5 and P-value < 0.05. Number of up- and down-regulated DEGs are indicated in each plot
