In addition to the population of cells with multilineage phenotype, cells with one or more of the following phenotypes were also observed in different glioblastoma cultures: MAP2+high/GFAP+/CD44-; CD44+/GFAP-/MAP2-; GFAP+/CD44+/MAP2-; MAP2+high/GFAP-/CD44-; CD133+/CD44+/MAP2+/GFAP+ and CD133+/MAP2-/GFAP- (Table 2). Here, GFAP is linked to glioblastoma.
