Orthotopic syngeneic models provide a more clinically relevant tumor microenvironment for immuno-oncology drug development studies. This includes an organ-specific tumor location, which allows metastasis, and also recapitulates immune and stromal component tumor interactions.

Bioluminescent imaging (BLI) enables real-time, non-invasive longitudinal monitoring of orthotopic tumor burden and end stage quantification of tumor spread.

This poster details the generation of a panel of bioluminescent syngeneic cell lines for orthotopic and metastatic modeling. These models allow the assessment of standard of care agents, immune checkpoint therapies, and combination regimens in a more clinically relevant environment.

Read this Poster to Discover:

• How the orthotopic microenvironment, with appropriate organ-specific vasculature, hypoxia, and stromal infiltration, provides the ideal model to assess immunotherapies, the response of which is heavily dependent on the TME
  
  
• How BLI enables longitudinal assessment of orthotopic tumors, which provides real-time quantification of tumor progression and therapeutic effect, with TIL assessed by IHC or FACS
  
  
• How bioluminescent imaging also allows the tracking of spontaneous metastasis and experimental metastasis models.
