What is the significance of using an orthotopic model?
Orthotopic models closely mimic the natural environment of tumors, providing more relevant biological insights.
How does luciferase imaging work?
Luciferase imaging allows for the visualization of tumor growth by detecting light emitted from luciferase-expressing cells.
What are the implications of tumor removal on metastasis?
Removing the primary tumor can alter the metastatic process, potentially providing insights into treatment strategies.
What are the advantages of using mice in cancer research?
Mice share genetic and physiological similarities with humans, making them ideal for studying cancer biology and treatment responses.
Can this model be used for other types of cancer?
Yes, the principles of this model can be adapted for various cancer types to study metastasis and treatment effects.
