摘要:: Keratin intermediate filaments (Ifs) are specific for epithelial cell differentiation. This study demonstrates the presence of keratin in two recently established human glioblastoma cell lines 8-MG-BA and 42-MG-BA. Immunofluorescence staining was performed on cells within passage 230 to 235 using monoclonal pan-cytokeratin antibodies. The cells were analyzed during several DIV at different cell density. Keratin-positive stained cells reached 5 to 7% in 8-MG-BA and less than 0.1% in 42-MG-BA cell line. The presence of keratin-positive cells was independent on cell density and days in vitro. Keratin-positive cells appeared unevenly distributed in both cell lines. They were observed as single or areas of keratin-positive cells. The morphological features of keratin-positive and keratin-negative cells were similar. The results are discussed with respect to previous studies on glial fibrillary acidic protein (GFAP) and vimentin to show the heterogeneity of IFs expression in glioma cell lines.
