FIG. 3.

Ability of TAg-transformed MEFs to grow to high density. Fifty thousand WT, INK4a^−/−, or ARF^−/− MEFs stably expressing the indicated TAg constructs were seeded on replica 100-mm-diameter plates and fed with complete medium containing 10% serum every 2 to 3 days. Triplicate plates were harvested at the indicated day after seeding, and cells were counted. Error bars indicate standard deviation.
