We found no obvious or consistent inverse correlation with tumor cell content as inferred from cytokeratin 19 (KRT19), epithelial cell adhesion molecule (EPCAM) and E‐cadherin (CDH1) expression (Fig. 1E), suggesting that the expression of stromal activation markers including SPOCK1 is not the consequence of increased stromal content. This evidence concerns the gene KRT19 and neoplasm.
