Glioblastoma cell culture protocol

A172 and U251 cells were obtained from the European Collection of Cell Cultures (EACC, UK) in 2014 and authenticated in 2020 by Cell Bank Australia using short tandem profiling. Cells were cultured in DMEM supplemented with 10% FBS and Antibiotic-Antimycotic solution (Life Technologies, Carlsbad, CA, USA) at 37 °C and 5% CO₂. Patient-derived HW1, RN1, MMK1 and RKI1 glioblastoma stem cells^{34 (link)} were cultured in KnockOut DMEM/F-12 supplemented with StemPro NSC SFM, 2 mM GlutaMAX-ICTS, 20 ng/mL EGF, 10 ng/mL FGF-β and Antibiotic-Antimycotic solution (all Life Technologies) as adherent cells on flasks coated with MatriGel (Corning, NY, USA). The protocols were approved by the Human Ethics Committee of the Royal Brisbane & Women’s Hospital (RBWH 2004/161). Cell cultures were routinely tested for mycoplasma infection and culturing did not exceed 15 passages.
