Prolonged animal survival is seen after co-inoculation of glioma with NPC. Co-inoculation of NPC together with glioma cells into the striatum of experimental fisher rats result in reduced tumor growth. The glioma N32 (2 × 103 cells) was stereotactically co-injected with the NPC, ST14A (2.5 × 104) into the striatum of fisher rats (n = 5/group). Antitumor properties for the other NPC lines are shown in our previous publications (Staflin et al. 2004, 2007). The percent survival was followed over time and statistical analysis of the Kaplan Meier curve was done using a chi square test **p = 0.0035.
