Monitoring Cancer Cell Invasion and T-Cell Cytotoxicity in 3D Culture
Research Overview
Immunotherapy has advanced, but many cancers resist it, and few assays let researchers watch tumor and immune cells interact directly. Most rely on 2D co-culture for convenience, which fails to represent invasive growth — a hallmark of cancer — while existing 3D systems need special equipment or monitor invasion and T-cell interaction separately.
This study addressed both limits with a 3D co-culture approach that monitors cancer cell invasion and T-cell interaction together, allowing mechanistic insight into how cytotoxic T cells engage invading tumor cells in a tissue-like setting.
Key Discoveries
- 3D co-culture monitors cancer invasion and T-cell interaction simultaneously
- Avoids the special equipment and separate readouts required by other 3D systems
- Captures invasive growth phenotype missing from conventional 2D immune co-culture
