Aim To establish ICR animal model with C6 glioma stem cells, to provide the ideal model for the further study of gli-oma stem cells in brain glioma model. Methods C6 glioma stem cell was cultured in vitro by suspension,and was identified with Nestin antibody. C6 stem cells of ICR mouse glioma model were used to investigate survival state and tumor volume in mice after the operation. HE staining and CD133 immunohistochemi-cal study were adopted to investigate the postoperative pathologi-cal changes in mice. Results The expression of Nestin was 96. 01% in C6 glioma stem cells, and Nestin was highly ex-pressed in the cultured C6 glioma stem cells. Mice were inocula-ted with tumor after loss of appetite, weight, behavior and slow, sluggish reaction. Tumor volume at day 21 after modeling was (9. 77 ± 6. 58) mm3 . After HE staining, the model showed the invasive growth, tumor cell shrinkage and derangement. Immu-nohistochemical CD133 staining revealed that tumor cytoplasm color was brown. Conclusion Glioma model can be established based on glioma stem cells into a high rate of tumor, the tumor cycle is short, which can be used as an ideal model for glioma.

Objective To study the temozolomide combined with curcumin on the inhibitory effect and apoptosis of the C6 glioma cells. Methods The C6 glioma cells were treated with temozomide in combination with curcumin. The anti proliferation effect of liposomes on the C6 glioma cells was investigated by using the method of sulforhodamine B (SRB). Flow cytometry was used to detect apoptosis of the C6 glioma cells. Confocal laser scan-ning microscope was used to observe apoptosis and location in the C6 glioma cells. Results The results of SRB as-say showed that temozolomide in combination with curcumin inhibition rate were (91.22 ± 0.51)%in 48 h of the C6 glioma cells; Flow cytometry showed that the apoptosis rate were (33.15 ± 0.79)% with temozolomide (5 μmol/L) in combination with curcumin (10 μmol/L). Laser scanning confocal scanning microscope indicated that the apop-tosis of in the C6 glioma cells treated with temozolomide in combination with curcumin was more than that of free drug. Conclusion The temozolomide in combination of curcumin can inhibit the growth and induce apoptosis of the C6 glioma cells.
