CELL LINE ISOLATION INFORMATION
The cell line U3073MG was established from a Glioblastoma tumor biopsy taken from a 71 years old male patient.
Dissociated cells from tumor tissue was allowed to grow as spheres onto uncoated dishes in complete culture medium [1:1 mix of Neurobasal and DMEM/F12 media supplemented with N2 (1x final conc), B27 (1x final conc), human recombinant FGF2 (final conc. 10 ng/ml) and human EGF (final conc. 10 ng/ml)]. These neurospheres were plated onto laminin coated dishes after 5 to 7 days to allow them to grow as adherent culture. Please read Xie et al., 2015 supplementary data for exact details.
