Tumor-formation ability of CD133+/CD44+ DU145 cells and parental DU145 cells
| Tumor-formation ratio | ||||
|---|---|---|---|---|
| 1W | 2W | 4W | 8W | |
| CD133+CD44+ cells (n=10) | 2/10 | 7/10 | 10/10 | 10/10 |
| Parental cells (n=10) | 0/10 | 1/10 | 4/10 | 5/10 |
| p value | 0.474 | 0.020 | 0.011 | 0.033 |
Tumor-formation ratio is expressed as the number of tumors formed to the number of mice injected. p values < 0.05 are considered statistically significant.
