Table 1. Tumor formation ability of sorted pancreatic CSCs.
Cell no. | 500 | 1000 | 5000 |
---|---|---|---|
CD133+ | 6/6 | 5/5 | 5/5 |
CD133- | 0/6 | 1/5 | 3/5 |
Assayed for the ability to form tumors after injection into the mice at 500, 1000, and 5000 cells per injection. Data are expressed as number of tumors formed/number of injections.
