FIG. 9.

Survival of GM00011 cells following exposure to UV light. NDFs were plated 24 h prior to irradiation. Following irradiation, colonies were allowed to grow for 2 weeks. The plated cells were then fixed and stained, and colonies were counted. Closed symbols indicate the colony-forming ability of NDFs carrying the vector alone following UV exposure; open symbols indicate the colony-forming ability of E7-expressing NDFs following UV exposure. The squares represent the results obtained when 500 cells were plated on each dish; the circles represent the results obtained when 1,000 cells were plated on each dish.
