Migration assays, in which melanoma cells migrated through collagen-coated transwells towards control or SOCS3-overexpressing microglia, demonstrated that YDFR.CB3, M12.CB, and M16.CB3 melanoma cells migrated towards SOCS3 overexpressing microglia cells much more effectively than towards control microglia (Figure 2g). Here, SOCS3 is linked to melanoma.
