dsRed 4 T1 xenograft in GFP nude rat. (A) Subcutaneous 4 T1 dsRed tumor in situ after removing the skin flap of the GFP nude rat (20× magnification). (B) Cell suspension of a dissociated 4 T1 tumor displays a mixture of individual GFP expessing host cells with dsRed transfected tumor cells (20× magnification).
