What is the significance of using an orthotopic model?
Orthotopic models closely mimic the natural environment of tumors, providing more accurate insights into cancer biology and treatment responses.
How does bioluminescence imaging work?
Bioluminescence imaging detects light emitted by luciferase-expressing cells, allowing for real-time monitoring of tumor growth and progression.
What are the advantages of non-invasive monitoring?
Non-invasive monitoring reduces the need for repeated surgeries, minimizes animal suffering, and allows for longitudinal studies of tumor dynamics.
Can this model be used for other types of cancer?
While this model is specifically designed for pancreatic cancer, the techniques may be adapted for other cancers with similar methodologies.
What are the potential therapeutic interventions that can be tested?
Various chemotherapeutic agents, targeted therapies, and immunotherapies can be evaluated using this model to assess their effectiveness against pancreatic cancer.
