Human primary glioblastoma or oligodendroglioma cells were transduced with 1 × 103 to 6 × 103 eGFP TU of LCMV-GP-, A-MLVenv-, or VSV-G-pseudotyped oncoretroviral or lentiviral vectors. Cells were analyzed by fluorescence microscopy after immunostaining with monoclonal anti-eGFP antibody and polyclonal anti-GFAP antibody (glia antigen). Results are the mean cell numbers from 10 random camera fields.
Mean cell numbers of eGFP+ GFAP+ double-positive transduced glioma cells from 10 random camera fields.
Mean cell numbers of GFAP+ glioma cells from 10 random camera fields.
Percent eGFP+ GFAP+ double-positive cells within the total number of GFAP+ glioma cells.
