To examine the FTL expression at the single cell level, we performed the single-cell analyses of 15 human glioma samples based on the GSE147275, and 9 clusters were identified (Figure 2F): T cells (Figure S3A), microglia (Figure S3B), tumor-associated macrophages (TAMs) (Figure S3C), neutrophils (Figure S3D), NKTs (Figure S3E), NK cells (Figure S3F), proliferative cells (Figure S3G), APCs (Figure S3H), and B cells (Figure S3I). The gene discussed is FTL; the disease is central nervous system cancer.
