Ovarian tumor cells express intracellular B7-H4. B7-H4 expression was analyzed by RT-PCR and FACS in (a) fresh primary ovarian tumor cells and (b) ovarian tumor cell lines. FACS results expressed the mean percentage of B7-H4–expressing cells. OC8, OC21, and OC38 are three established ovarian tumor cell lines. Fresh primary ovarian tumor cells were isolated and sorted from ascites and tumor tissues with a phenotype of linEpCam+CD45CD14. Two of six representative patient samples are shown for panel a. Three of eight cell lines are shown for panel b. Filled histogram, B7-H4 expression; open histogram, isotype control.
