Doubling time for Epo-sensitive and Epo-resistant cell lines.
Cells (40,000 cells/well) were seeded in a six-well plate and allowed to grow to 80% confluency. The total number of cells in each well was counted, and the length of incubation was used to obtain the doubling time.
| Cell line | Doubling time (h) | Increase (%) |
|---|---|---|
| A549 | 23.5 | |
| A549.EpoB40 | 31.8 | 35 |
| HeLa | 19.5 | |
| HeLa.EpoA9 | 21.5 | 10 |
| HeLa.EpoB1.8 | 43.3 | 122 |
