Because fewer than 6% of these glioma-associated F11r+ cells were dendritic cells, B cells, or NK cells as determined by flow cytometry using CD3, CD4, CD11c, CD8a, CD19, CD103, and NK1.1 antibodies (data not shown), we hypothesized that Sell+ BMDM acquire F11r expression following brain infiltration in GBM. This evidence concerns the gene ITGAE and central nervous system cancer.
