Fresh tumor ascites macrophages were stained with mouse anti-human B7-H4, anti-human CD40, CD54, CD80, CD86, HLA-ABC, and HLA-DR. Results are expressed as the mean percentage of the positive cells for the relevant molecules on B7-H4+ macrophages and B7-H4- macrophages. Mean ± SEM is shown (n = 5-12). MFI, mean fluorescence intensity.

aP = 0.04 (Wilcoxon test).
