Co-expression of B7H1 and CD133 in HT29 cells and colorectal cancer tissues.

<p>The expression of CD133 (red) and B7H1 (green) in HT29 cells (A) (Bar = 20 μm), and expression of EpCAM (blue), CD133 (red) and B7H1 (green) in colorectal cancer tissues (B) (Bar = 50 μm) were determined by immunofluorescence staining. The nucleuses were stained with DAPI (grey). The rectangle area in the image is enlarged (C) and shows a typical co-expression of CD133 and B7H1 (indicated with arrows). It is shown a representative rectal moderately differentiated adenocarcinoma, T3N0M0.
