Pairwise similarity, a measure of marker-like co-expression, of selected marker genes in TCGA. Values of 1 indicate perfect marker-like co-expression. a Mean log2 expression vs. average pairwise similarity of selected cell type markers across TCGA datasets. Cell types in grey have been discarded from the final panel of markers. b Average pairwise similarity of each cell type’s marker genes in each TCGA dataset
