Activation of Notch1 signaling in human primary nasopharyngeal carcinoma (NPC) A, Notch1 (green; left panel) and Jagged1 (green; right panel) proteins were expressed in human primary NPC cells. Nuclei were counterstained by DAPI (blue). B, NICD protein (red) was expressed in the Notch1-positive cells (green) in human primary NPC. C, Hes1 protein (red) was expressed in the Notch1-positive cells (green) in human primary NPC. D, NICD (green) was expressed in the Ki-67-positive cells (red) in human primary NPC. Nuclei were counterstained by DAPI (blue).
