This video demonstrates the orthotopic transplantation of zebrafish brain tumor cells into the fourth ventricle of an immunocompetent zebrafish embryo. This procedure allows for the long-term study of tumor cell invasion and behavior.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Injecting the Tumor Suspension into the Fourth Ventricle of a 2-dpf Embryo Transfer 10–20 anesthetized dechorionated embryos to the periphery of the injection plate using a transfer pipette; the embryos should fall laterally onto the injection plate, with the ventricles clearly visible and accessible. Use an angle…
