This video demonstrates a stereotaxic injection technique for administering human effector T lymphocytes into a murine model carrying a human brain tumor. Upon positioning a tumor-bearing anesthetized mouse on a stereotactic frame and creating a burr hole at the injection location on the skull, effector T lymphocytes are injected at the tumor site.
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. Non-specific Expansion of Cytotoxic Effector T Lymphocytes Prepare and irradiate feeder cells at 35 Gy. For the stimulation of 2 x 105 – 4 x 105 effector cells, prepare 10 x 10…
