This video demonstrates the establishment of luciferase-tagged glioma stem cells via lentivirus-mediated gene delivery. Luciferase acts as a reporter gene and helps facilitate rapid drug screening experiments.
Protocol
1. Preparing Luciferase-tagged GSCs
Begin with the GSCs culture and centrifuge at 70 x g for 3 min at room temperature.
Remove the supernatant and digest the cells with accutase for 4 min at 37 °C. Use a 200 µL tip and pipette repeatedly to dissociate and resuspend the cell pellet.
Dilute the cells to 2 x 105 cells per well in a 12-well culture plate and culture the cells overnight.
Add 30 µL luciferase-EGFP virus supernatant (titer >108 TU /mL) into each well in the plate and then centrifuge the cells at 1,000 x g for 2 h at 25 °C. Culture the cells overnight.
Refresh the medium the next day and culture the cells for another 48 h.
Observe the cells under a fluorescent microscope to confirm the appearance of the GFP-positive cells.
Use a flow cell sorter to sort and select the GSCs with high GFP fluorescence to culture the cells further.
