A smaller tissue from patient ID 9561, collected in 2008, had four clusters, including melanoma (PMEL, TYRP1), immune cells (TMSB4X, IL32), keratinocytes (KRT10, KRT1, DSG1), and fibroblast areas (COL1A2, COL1A1, DCN) (Figure 5D–F, and supplementary material, Figure S5B and Table S8). Here, IL32 is linked to melanoma.
