Glioblastoma Cell Lines and Glioma Stem Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human glioma cell lines U118MG, U87MG, LN229 and U251MG were purchased from the Chinese Academy of Sciences Cell Bank and cultured in DMEM medium (Gibco, USA) with 10% fetal bovine serum (FBS). The neural progenitor cell (NPC) and GBM patient-derived GSC cell lines and were kindly donated by Dr. Krishna P.L. Bhat (The University of Texas, M.D. Anderson Cancer Center, Houston, TX). GSC lines (GSC20, GSC267, GSC8–11, GSC11) have been used extensively in previous studies and the subtypes of GSCs have been clarified according to the Verhaak or Philips gene signatures, respectively. GSCs and NPC were cultured in DMEM/F12 (Gibco, USA) with 2% B-27 no serum supplement (Gibco, USA), 20 ng/mL human recombinant bFGF (R&D Systems) as well as 20 ng/mL human recombinant EGF (R&D Systems, USA). The GSC or NPC spheres were digested using accutase solution (Sigma-Aldrich, USA). All cell lines were cultured in a humid chamber at 37 °C and containing 5% carbon dioxide and 5% oxygen.

U118MG, U87MG, and U251MG cells were purchased from the Chinese Academy of Sciences Cell Bank (China) and LN229, LN18, A172, and T98G cell lines were obtained from ATCC (USA). TJ905 cell was separated from human GBM tissue and was cultivated in a mixture consisting of 10% fetal bovine serum (FBS, Gibco, USA) and DMEM/F12 medium (Gibco, USA). DMEM (Gibco, USA) mixed with 10% FBS was used to cultured other seven glioma cell lines which were incubated in 5% CO 2 at constant temperature of 37 °C. Cells were identified by polymorphic short tandem repeat profiling in advance and tested every 6 months for excluding mycoplasma contamination.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
