Supporting the transcriptional data, we detected ZEB1 positive (+) CD68+ macrophages by immunofluorescence (IF) stainings of human CRC (Fig. 1e) and mouse lung metastases (Fig. 1f) formed upon tail vein injection (tvi) of pancreatic ductal adenocarcinoma (PDAC) cells28. This evidence concerns the gene ZEB1 and colorectal carcinoma.
