Description Of The Surgical Procedure
Intracranial inoculation of glioma cells. The skin was sterilized by ethanol and a 1 cm sagittal incision was made to expose the bregma. A hole was drilled at the coordinates A +1, L -2 and V -3.5 mm in relation to bregma. 5 ?l cell suspension (200 000 cells) was aspirated into a 25 ?l Hamilton syringe (Model 1702 N). The syringe was mounted onto a stereotactic frame and inserted into the brain slowly for 4 mm and then retracted 0.5 mm, before the injection. The injection was performed over 3 minutes and 2 minutes later the syringe was slowly retracted.
