We found that while melanoma cell lines expressing mutant KIT migrated over 7mm away from the seeding area after 2 weeks of 3D culture, BRAF mutant melanoma cells and wild type melanocytes only migrated less than 4mm from the seeding site at 2 weeks (Figure 2; 2-sided student t-test; p<0.05). This evidence concerns the gene KIT and melanoma.
