What is the significance of using MB49 cells?
MB49 cells are a well-established model for bladder cancer research, allowing for the evaluation of therapeutic strategies.
How long does the entire procedure take?
The procedure involves initial implantation followed by adenoviral delivery eight days later, with results assessed 24 hours post-delivery.
What are the risks associated with catheterization?
Potential risks include bladder damage and leakage of instilled materials, which can be mitigated with proper technique.
Why is luciferase used in this study?
Luciferase serves as a reporter gene, enabling the quantification of gene expression in response to adenoviral delivery.
Can this model be used for other types of cancer?
While this protocol is specific to bladder cancer, similar techniques may be adapted for other cancer types with appropriate modifications.
What is the next step after establishing this model?
Researchers can use this model to test various therapeutic agents and assess their efficacy in treating bladder cancer.
