Human Glioma Nude Mouse Xenograft Model in situ

Backgrounds Surgery and chemotherapy are difficult because of the specific location of the glioma. The establishment of a suitable in situ model of glioma is the premise of the treatment of glioma. 8 week-old female BALB/c nude mice were chose to establish the glioma model.

Methods For the orthotopic glioma mice model, 1 × 10⁵cells/5 μL U87-MG-Luc or U87-MG cells which were trypsinized and resuspended in sterile PBS were slowly injected into the right corpus striatum (1.8 mm lateral, 0.6 mm anterior to the bregma and 3.0 mm in depth) by a stereotactic fixation device using a mouse adaptor.

Results The othotopic U87 glioma mice model identified by imaging on IVIS Spectrum and magnetic resonance imaging after 2 weeks from surgery. H&E-stained tumor sections in brain of the mice model were also observed.

Conclusions After identification, the glioma mouse xenograftin situmodel obtained could be used in the evaluation system of therapeutic drugs or methods.
