I Ex vivo luminescence images of bones, brain, lungs and liver from MM134 engrafted mice 1 month post injection (top) and ovaries (bottom) 12 months post injection. Scale bar, 1 cm. J Dot plot showing ex vivo bioluminescence of different organs from mice xenografted with MM134 and SUM44 cells plotted over organ and time of analysis. Number of mice analyzed MM134 and SUM44 for 30-180: N=5, 10, 180-270 days: N=9, 5, 270-360 days: N=14, 20, respectively. Dashed line indicates background levels.
