The histological features of patient pancreatic adenocarcinomas (left hand panels: A, C, E, G) are maintained when these tumors are grown as xenografts (right hand panels: B, D, F, H) in SCID mice. The well differentiated glands (arrows) containing secretory material (double arrows) which are seen in surgical specimens, proliferate in xenografts of the same tumors. (Tumor #1: A, B; Tumor #2: C, D; Tumor #3: E, F; Tumor #4: G, H). Original magnification, ×10.
