Follow the leader? This image shows cells in a primary breast cancer tumor invading the surrounding muscle tissue (blue). Both the green and pink-stained cells are tumor cells, but the pink cells represent ‘leader’ cells – cells that break off from the main body of the green tumor and begin to metastasize, a process by which cancers from a primary tumor invade and colonize other tissues. These leader cells are both genetically and behaviorally different from the main body of the tumor. Researchers hope to identify the genetic mutations that cause cells to become ‘leaders’ to give them new opportunities for treating breast cancers and preventing metastasis.
The downloadable Educator Materials PDF includes background information and implementation suggestions for using the image as an anchoring phenomenon. The Student Handout includes the image and background.
