Immunohistochemistry and immunofluorescence analysis of human PDAC. (a) Representative images from immunohistochemistry analysis of human PDAC samples from post-mortem showing ectopic PNAd⁺ venules (marked by * in the images, n = 6, scale bar = 100 μm). (b) A representative high-magnification IHC image of a PNAD⁺ vessel in the PDAC (Scale bar = 75 μm). (c) Immunohistochemistry staining of the human PDAC prior to implantation into the NSG mice confirming PNAd expression in the tissue. (d) Representative images of PNAD⁺ vessels (green) surrounded by Fibronectin (red) and αSMA (red) (Scale bar = 100 μm).
