What are zebrafish xenografts?
Zebrafish xenografts involve injecting human tumor cells into zebrafish to study cancer behavior in a living model.
How long does it take to observe tumor behavior?
Tumor behavior can be observed within a short time frame, typically around four days post-injection.
What imaging techniques are used?
Confocal and light sheet microscopy are used for live imaging of tumor cells in zebrafish.
Can patient-derived cells be used in this model?
Yes, the protocol can be adapted to use patient-derived cells from surgical samples or biopsies.
What advantages do zebrafish models offer?
Zebrafish models allow for real-time observation of cancer hallmarks and interactions within the tumor microenvironment.
What are the key steps in the injection process?
Key steps include preparing embryos, labeling cells, and carefully injecting the cell suspension into the embryos.
