Zeta Mv 28.80
Model Scope in_vivo
Model Type in vivo orthotopic brain tumor uptake/cell-tropism imaging
Cell Lines Or Primary Cells U87-CMV/Fluc+ human glioblastoma cells
Animal Model NSG mice bearing orthotopic U87-CMV/Fluc+ brain tumors
Administration Route intratumoral/intracranial injection using stereotaxic frame
Output Type in vivo uptake / tissue distribution imaging
Output Value WRAP5:siFluc-Cy3 PBNs detected in tumor region 8 h after injection; histology showed PBN signal in CD44+ tumor cells and also GFAP+ glial cells and NeuN+ neurons.
Output Units
Output Notes This row records direct uptake/cell-tropism evidence in a separate orthotopic model. No functional reporter knockdown was quantified for this orthotopic experiment, so delivery_success_class remains 0.
Toxicity Notes No toxicity assessment specific to this orthotopic uptake experiment was reported.
