Anti-TGF-β antibodies specifically blocked the effect observed by the A375 (from 152 to 62 gMFI) and RPMI-7951 (from 239 to 64 gMFI) conditioned medium (Figure 4C), thus suggesting that TGF-β is released by the A375 and RPMI-7951 melanoma cell lines and affects MC activities. Here, TGFB1 is linked to melanoma.
