Distribution of size and proliferation of tumors.

<p><i>Braf^CA/+</i> mice were infected with as indicated and tumor size vs. proliferation as measured by Ki67 staining at 16 weeks post-infection. Each dot on the graphs represents a single tumor, for which the surface area and the percentage of KI67-positive cell was determined. The cDNA encoded in each LEX-iCL lentivirus used to infect mice is indicated on each graph.
