Cancer cells exhibit a remarkable number of traits normally attributed to white blood cells known as macrophages, including the ability to migrate to lymph nodes and distant organs and to form a new blood supply. Our data indicate that they do this by hybridizing with macrophages. |
There is now evidence to support all aspects of his proposition. Macrophages are among the most motile cells we have. By co-opting the macrophage's ability to move, the hybrid is very different from the original cancer cell. It is able to migrate away from the primary site of tumor formation and take up residence in other areas of the body while it continues to divide. |
