We noticed that some gB positive cells (green color, Figure 2A) exhibit CD11B-negative/CD45-negative phenotype (green color, Figure 2B), and the majority of gB positive cells represent a OLIG2-positive subclass of glioma cells (yellow signal of colocalization, Figure 2C and Supplementary Figure S1A) or exhibit strong expression for SOX2 (Supplementary Figure S1B). Here, SOX2 is linked to central nervous system cancer.
