B16 cell tumor formation and LN metastasis following footpad inoculation. (A) Footpad tumor volumes (mm3) were measured by a caliper at the indicated dose and time-point. n.s., Not significant. (B) Representative photos (21 days postinoculation) of draining popliteal LNs from pLNCX2-B16 (left)- or CCR7-B16 (right)-injected footpads (4×105 cells/footpad) are shown. One of four experiments with similar results is shown.
