RNA-seq of sorted cd8a:EGFP+ myeloid cells from melanoma revealed gene expression resembling murine CD8+ DCs that, in mammals, cross-present antigens with high efficiency to CD8+ T cells.12These cells expressed the zebrafish myeloid markers mpeg and mfap4 but not the neutrophil marker mpx (Figure S1G). This evidence concerns the gene MFAP4 and melanoma.
