In contrast, the B16F10 mouse melanoma cell line, which exhibited less SCGB3A2-dependent growth suppression effects than LLC in vitro (data not shown), showed focal expression of SDC1 near cell nuclei and faint staining at cell-to-cell contact sites (Figure 3D), while the total cell surface staining was low compared to LLC cells. Here, SCGB3A2 is linked to melanoma.
