As expected from previous experiments [30], in this set up the epithelial ZR75-1 breast cancer cells stained positive for Pan-CK, HER2 and Ki67, whereas the T98G glioblastoma cell line was positive for Ki67 and vimentin but remained negative for Pan-CK and HER2 (Figure 5 and Table 2). This evidence concerns the gene VIM and breast carcinoma.
