Immunohistochemistry analysis of uPA and uPAR expression in human testicular germ cell tumor. Tissue sections from 10 cases of seminomas were incubated with antibodies against human uPA or uPAR and processed as described in the Methods section. A) A representative normal testis stained with uPA antibody. B) A representative normal testis stained with uPAR antibody. C) A representative seminoma stained with uPA antibody. D) A representative seminoma stained with uPAR antibody. E) Negative control for seminoma tissue obtained omitting the first antibody. Tissue sections were counterstained with Mayer hematoxylin. Scale bar = 30 μm.
