Intramedullary Spinal Cord Glioma Following Microinjection of Glioblastoma Cell Line C6 in Rats

Background: This paper describes the establishment of a rat intramedullary spinal cord tumor (IMSCT) model and histopathological characterization of the tumor model. Methods: Fourteen male Wistar rats were randomized into two groups. The rats in group 1 (control group, n = 7) received a 5 μl intramedullary injection of serum physiologic (SF). Those in group 2 (experimental group, n= 7) received a 5 μl intramedullary implantation of media containing 5 × 105 C6 glioma cells. The animals were sacrificed for histopathological examination at 21 days. Results: The control group showed normal functional and histopathological findings. The group 2 rats implanted with C6 glioblastoma cells developed hind-limb paraplegia. Pathological sections confirmed intramedullary C6 glioblastoma invading the spinal cord. Conclusions: A rat C6 IMSCT model was successfully established. This model may be useful in increasing understanding of intramedullary spinal cord gliomas in humans.

GFP报道基因转染大鼠C6胶质瘤细胞系动态表达的研究

目的:研究绿色荧光蛋白报道基因体外转染C6胶质瘤细胞系的动态表达。方法:脂质体转染后荧光显微镜筛选荧光克隆、激光共聚焦显微镜观察荧光蛋白在细胞内分布,并分析荧光蛋白转染细胞后对其增殖能力的影响。结果:荧光蛋白主要分布在细胞核周围区域。冻存后复苏对细胞存活和荧光强度没有明显影响。C6细胞的增殖没有明显变化。结论:荧光蛋白可以作为胶质瘤基因转染时的优选报道基因。
