- Oncology
Background
- Non-adherent effector T lymphocytes play a crucial role in immune responses.
- Understanding their migration can provide insights into cancer immunotherapy.
- Existing methods for studying cell migration have limitations.
- This study aims to improve the measurement of T lymphocyte mobility in co-culture with tumor cells.
Purpose of Study
- To demonstrate the migration of non-adherent effector T lymphocytes over adherent tumor cell monolayers.
- To assess the functionality of these lymphocytes in a co-culture environment.
- To evaluate the advantages of the cell sedimentation manifold technique.
Methods Used
- Establishment of a monolayer of adherent tumor cells on poly D lysine coated Teflon slides.
- Fluorescent labeling of effector T lymphocytes.
- Use of a cell sedimentation manifold to deposit lymphocytes onto the tumor cell monolayer.
- Visualization of cell migration using light and fluorescence microscopy.
Main Results
- Effector T lymphocytes successfully migrated over the tumor cell monolayer.
- The migration and effector functions were maintained post-transduction with a retroviral vector.
- This method allows for precise measurement of radial migration.
