34 Interestingly, it has been shown that the CD271 antibodydetects two subpopulations of cells in GBM, stem cell-like cells andthe rapidly migrating cells.35,36 We therefore pursueda double staining experiment with p-HTMI and CD271 antibodies in GSCcultures and found by FACS that the cell populations in GSC culturesstained by p-HTMI and CD271 are vastly overlapping (Figure 3e). Here, NGFR is linked to glioblastoma.
