The progenitor cluster (ProgNP) (1%), distinguished by the expression of PDGFRA and PLA2G2A, was unique to the non-degenerative samples as reported by Gan et al.14 In addition to 5 NPC clusters, we also identified neutrophils (LYZ+), granulocyte-like myeloid-derived suppressor cells (G-MDSC+; MPO+), macrophages (CD68+), T cells (TRBC2+), endothelial cells (CD34+ and PECAM1+), pericytes (RGS5+ and ACTA2+), and erythrocytes (HBB+) (Fig. 1d, e). This evidence concerns the gene PLA2G2A and nasopharyngeal carcinoma.
