NCR3LG1 and cervical carcinoma: We are among the first to show the presence of B7-H6 in these cell lines, and these results are in line with a recent report by our group, where the expression of B7-H6 was consistently seen in cervical cancer specimens [20] As the expression of B7-H6 was not present in the totality of HeLa or SiHa cells, we tried to sort the B7-H6 positive and B7-H6 negative population and found that B7-H6 was selectively maintained or lost in the tumor cell lines.
