Then, based on the following cell markers, we performed cell typing: Tumor cells (MLANA, MITF), T cells (CD3D, CD8A), B cells (CD19, MS4A1, CD79A), Plasma cells (CD79A, IGHG1, MZB1), monocytes and macrophages (CD68, CD14), Retinal pigment epithelium and Photoreceptor cells (RCVRN, RPE65), Fibroblasts (COL1A1), Endothelial cells (PECAM1, VWF). This evidence concerns the gene MZB1 and neoplasm.
