Characterization of two new permanent glioma cell lines 8-MG-BA and 42-MG-BA.
The establishment and characterization of two permanent glioma cell lines (8-MG-BA and 42-MG-BA) are described. Both cell lines were derived from the human glioblastoma multiforme. Analyzed cells were within the passage 200 to 220. The cells in both cultures showed similar morphology. In majority they consisted from flat polygonal cells. Growth kinetic studies demonstrated a population doubling time of 20 to 24 h in cell line 8-MG-BA and 48 to 54 h in cell line 42-MG-BA. The cell lines showed different hyperdiploid karyotypes. The immunofluorescence staining was performed for glial fibrillary acidic protein (GFAP) and vimentin. In the culture 8-MG-BA only a small amount of cells showed the GFAP-positive staining. At confluent 42-MG-BA culture the GFAP-positive cells reached 50 to 70% of all cells. Vimentin was found in all glioma cells in both cultures.
