Comparing glioblastoma tumor cell states in NF1-mutant to NF1 wild-type glioblastomas, no significant differences in the proportion of tumor cells in a given cell state was observed, though a trend toward increased MES-like cells in NF1-mutant tumors was noted as previously described (Supplemental Figure 8B) (2, 7). The gene discussed is NF1; the disease is glioblastoma.
