Innovative movies show real-time immune-cell activity within tumors

Published in Medical Devices and Surgical Technology Week, December 17th, 2006

Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists at The Wistar Institute have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues. In recorded experiments, immune cells called T cells can be seen actively migrating though tissues, making direct contact with tumor cells, and killing them.

Insights from this new view of the body's on-board defenses against cancer may open the way for improved immunotherapies to treat the disease.

With a series of movies made under different experimental conditions, the researchers...
