A. MSTO parent, MSTO-CD26 or JMN cells were implanted subcutaneously (s.c.) in the flank of SCID mice. The in vivo tumor samples were stained with hematoxylin and eosin (H&E) (i), or purified mouse anti-human CD26 mAb (19–32 (ii), U16-3 (iv), U38-8 (v)), or purified goat anti-human CD26 pAb (R&D Systems (iii)). Original magnification, 20x. B. The tissue specimens of liver, kidney, prostate or two cases of malignant mesothelioma were stained with purified novel mouse anti-human CD26 mAbs (U16-3 (i) or U38-8 (ii)). Original magnification, 4x. All specimens were counterstained with hematoxylin.
