In all experiments, HeLa cells, which are derived from adenocarcinoma of the cervix, expressed B7-H6 at around 48.5%, meanwhile SiHa cells (squamous cell carcinoma), similarly expressed B7-H6 at around 48.9%, on the cell surface as shown in Fig. 1a and b, respectively. This evidence concerns the gene NCR3LG1 and squamous cell carcinoma.
