Cancer metastasis video wins AAMC top prize
In a new video, Winship Cancer Institute researchers shows how they're isolating and studying the behavior of "leader" cells that may be the key to cancer metastasis.

A video starring Winship Cancer Institute researchers has won first place in the GRAND Basic Research video contest, the Association of American Medical Colleges (AAMC) announced on Monday, Nov. 9. The video features techniques for studying metastatic cancer cells developed by cell biologist Adam Marcus and graduate student Jessica Konen. 

The idea of precision medicine is based on the observation that cancer cells in two different people may respond differently to treatment, based on the mutations that drive the cells' growth, even though they may come from the same organ and even look similar under the microscope.

Winship researchers are extending that concept to highlight how even in a single tumor, not all the cells are the same. Some may divide or migrate faster than others. A few cells might survive chemotherapy that kills the rest.

The capacity of cancer cells to spread throughout the body and invade new tissues — to become metastatic — makes them deadly. What makes metastatic cells different?

The isolation technique seeks to probe these differences in cellular behavior. In the accompanying video, Marcus and Konen explain how they came up with the combination of labeling one or a few cells in culture, by changing them from fluorescent green to fluorescent red, and sorting out the labeled cells. The technique allows them to ask and answer questions such as:

  • Is the property of migrating faster (being a "leader cell") long-lasting and stable?
  • And, is that property connected with changes in the cell's DNA? Do leader cells and follower cells need each other to cause metastatic disease?

This approach is expected to yield new insights into cancer cell biology, which may lead to new treatments that hamper metastasis.
