Figure 9. Combination treatment decreases the number of actively dividing cells in a transplantable mouse model of breast cancer. Quantification of the number of actively dividing cells in tumor sections using Ki-67 staining. (A) Tissue sections show the amount of positive cells. The stain is specific for cells that are actively dividing. (B) Quantification of the staining using Image J software. Data represent mean values from three different fields and error bars represent standard deviations from the mean.
