Animal experiments were performed in accordance with a study protocol approved by the Institutional Animal Care and Use Committee of the University of Tennessee Health Science Center. Xenografts were established in five-week-old male NOD.Cg-PrkdcscidIl2rgtm1Wjl/SzJmice (Jackson Laboratory) by injection of MT330 and SJG2 cells (1x106) directly into the flanks [37 (link)]. Tumors were measured weekly with a handheld caliper. In addition, luciferase-expressing GBM cells (106) were injected stereotactically into the superficial brain parenchyma of NSG mice through a burr hole in the skull as previously described [49 (link)]. NSG mice were injected with D-luciferin and subjected to live animal imaging weekly to quantify bioluminescence [38 (link), 49 (link)].
