Normalized expression levels of human genes. The expression levels of human ACTB and OAZ1 reference genes and EPCAM and KRT19 epithelial markers were normalized on murine reference gene Actb, for each PDX sample. Data were expressed as ΔCt values and graphed, sorted on human OAZ1 content. Samples were analyzed in two independent assays for mActb; for human transcripts, qPCR was repeated in four (KRT19) or five (ACTB, OAZ1, EPCAM) independent assays for each gene. In each run, each RNA was measured in duplicate
