In (a) pancreatic ductal adenocarcinoma sample stained with the anti-tryptase antibody. Big arrow indicates a single red MC and small arrow indicates a microvessel with its lumen. The lumen is marked with an asterisk and there are well visible intraluminal red blood cells. In (b) a highly vascularized pancreatic ductal adenocarcinoma sample stained with the anti-CD-31 antibody. Big arrows indicate single red microvessels with their own lumen and small arrows indicate the bleu nucleus of cancer cells. Magnification: (a-b), 1000 in oil.
