Gene expression variation. Principal component analysis of protein coding genes. a All human, bulk samples (165,880 samples) with color indicating the library size. b As (a) but only including samples with a labeled tissue (41,218 samples) colored by tissue. c As (a) but only including blood samples (4731 samples) with color differentiating blood and lymphoblastoid cell lines (LCL) samples. Appendix: Fig 12 shows the variation across bulk and single-cell RNA-seq. The percentage of variance explained by the principal component (PC) is given in the axis labels
