DLL3 expression in normal and tumor tissue. DLL3 protein expression via immunostaining (brown color) in A normal pancreatic tissue and B an SCLC tumor section [114]. Staining for DLL3 expression shows weak expression with a cytoplasmic pattern of localization in normal human pancreatic tissue sections (Panel A) and strong membranous and cytoplasmic expression in human SCLC (Panel B). Arrows in Panel A point to pancreatic islet cells. Blue hematoxylin counterstain is used to visualize cell nuclei. Original objective, ×200. DLL3 delta-like ligand 3; SCLC small cell lung cancer
