Abstract
Glioblastoma is the most common brain tumor that causes significant mortality annually. Limitations of the current therapeutic regimens warrant development of new techniques and treatment strategies in orthotopic animal model for better management of this devastating brain cancer. There are only a few experimental orthotopic models of glioblastoma for pre-clinical testing. In the present investigation, we successfully implanted rat C6 cells via intracranial stereotaxic cannulation in adult Sprague-Dawley rats for development and histoimmunopathological characterization of an advanced orthotopic glioblastoma allograft model, which could be useful for investigating the course of glioblastoma development as well as for testing efficacy of new therapeutic agents. The orthotopic glioblastoma allograft was generated by intracerebral injection of rat C6 cells through a guide-cannula system and after 21 post-inoculation days the brain tumor was characterized by histoimmunopathological experiments. Histological staining and immunofluorescent labelings for TERT, VEGF, Bcl-2, survivin, XIAP, and GFAP revealed the distinct characteristics of glioblastoma in C6 allograft, which could be useful as a target for treatment with emerging new therapeutic agents. Our investigation indicated the successful development of intracranial cannulated orthotopic glioblastoma allograft in adult Sprague-Dawley rats, making it as a useful animal model of glioblastoma for pre-clinical evaluation of various therapeutic strategies for the management of glioblastoma.
