This video describes the method for transplantation of tumor cells from the melanoma-bearing donor zebrafish model to an immunocompromised recipient Casper zebrafish. It helps to visualize tumor engraftment and proliferation in the recipient fish.
Protocol
All procedures involving animals have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Transplantation Assay Prepare recipient 2-3 month old Casper fish by irradiating with 25 Gy of gamma irradiation one day prior to transplantation. Allow the fish to recover in fish water. Euthanize a tumor-bearing fish according to institutional guidelines. Specifically, a fish is placed into a dish with 0….
