This video demonstrates an assay to generate a humanized xenograft mouse model. An immunocompromised mouse is injected with cyclophosphamide to cause immune cell depletion. Patient-derived tumor cells mixed with human peripheral blood mononuclear cells (PBMCs) in a hydrogel are subcutaneously injected into the mouse, forming a tumor with infiltrating T cells.
Protocol
All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1.
