Figure 5A illustrates the distribution and abundance of the various cell types. AC-like malignant cells and CD8+Tex cells were found to predominantly express MSN, whereas MT3 exhibited predominant expression in malignant cells, AC-like malignant cells, MES-like malignant cells, OPC-like malignant cells, and oligodendrocytes, with minimal expression observed in NPC-like malignant cells and immune cells, CD8+Tex (Figures 5B, 6). Here, MSN is linked to nasopharyngeal carcinoma.
