Increased clonogenicity in the CER variants than their parental cell lines. We performed the assay in low-FBS medium as described in Materials and Methods. Comparison of the plates showed that the CER variants are more clonogenic than the parental cell lines, and 2) the CER variants are inhibited with celecoxib in this assay. Passage numbers: SUM149, 24 ; SUM149-CER, 4; BSC60, 9; BSC60-CER, 7.
