Multidimensional scaling plot of Colo205 and HCT-116 samples. Multidimensional scaling plot showing the relatedness of individual samples from Colo205 and HCT-116 to each other in 2D space. The color indicates the size of the tumor sample when harvested: red, 200 mg; blue, 500 mg; black, 1000 mg. The size of text indicates the mouse strain the tumor was grown in: small, Nu/Nu; large, C.B-17 SCID. Samples that are more related to each other are closer together. For Colo205 five samples were analyzed.
