Class I MHC expression on primary and metastatic prostate tumor cells

Primary (PA) or metastatic (LMD) prostate tumor cells were incubated with or without different amounts of IFN-γ for 2 days. Surface class I MHC expression was measured in mean fluorescence intensity, and the percentage of positive cells is in parentheses.
