In order to identify malignant cells from non-malignant cells, we first calculated the average score of sialoblastoma markers reported in previous studies (KRT5, KRT14, KRT23, TP63, EPCAM, KRT7, KRT19, KRT18, ACTA2, CNN2, S100A2), showing that epithelial cells have the highest tumor score (Supplementary Figure S2C). This evidence concerns the gene S100A2 and neoplasm.
