Experiments were performed on 28 sexually mature Wistar rats divided into two equal groups. Rats were fixed in stereotactic apparatus and received 2.8×105 C6 glioma cells in 20 μl of F10 medium locally into frontal region of brain under ketamine-xylazine-acepromazine anesthesia. One group of rats (n=14) was implanted with 40×104 MSCs in 40 μl of low glucose DMEM medium into submucosa of nasal cavity. Further, only rats from this group received 40×104 mesenchymal stem cells (MSCs) intranasally in the form of a spray on a weekly basis. All 14 rats from the second group died within two months. Rats with implanted MSCs started to die in two and a half months. Two rats lived up to 8.5 months. One of these rats was decapitated, brain slices stained with hematoxylin-eosin and Nissl – and no tumor cells were found. A connective tissue scar was found at the site of injection.
