Quantification of Clonal and Nonclonal Changes Per DU145 Cell Line.
| Cell Line | Clonal Changes | Nonclonal Changes | |
| DU145 Parental | Total | 11 | 40 |
| Normalised per cell | 0.65 | 2.35 | |
| DU145 SCC1 | Total | 8 | 23 |
| Normalised per cell | 0.67 | 1.92 | |
| DU145 SCC2 | Total | 1 | 13 |
| Normalised per cell | 0.07 | 0.93 | |
| DU145 SCC3 | Total | 8 | 14 |
| Normalised per cell | 0.62 | 1.08 | |
For each cell line, the total numbers of clonal and nonclonal changes were determined and normalised by dividing by the total number of cells analyzed (17, 12, 14, and 13, respectively). These results objectively support that there is more homogenous pattern of numerical changes in SCC2 than in SCC3 and SCC1. Note that the rate of nonclonal changes approaches that of the parental DU145 cell line, indicating the presence of a CIN-like process.
