Experimental metastasis of B16 melanoma cells in anti-asialo GM1 antibody-treated mice. Photographs of the metastatic colonies in the lungs (a–c, g–i) and the liver (d–f, j–l) were taken 14 days after the intravenous injection of 1 × 105 B16 melanoma cells. Wild-type: a, d, g, j; IFN-γ−/−: b, e, h, k; IFN-γR−/−: c, f, i, l; treated with anti-asialo antibody: g–l; without treatment: a–f.
