The mouse anti-NANOG primary antibody (Fig 7M–7O; green) produced a weaker stain than the rabbit anti-NANOG (Fig 7J–7L; red), but was detected in the cytoplasm of tumor epithelial cells, which showed cytoplasmic and membranous expression of AT2R (Fig 7M–7O; red). This evidence concerns the gene NANOG and neoplasm.
