Microfluidics device tracks breast cancer cell movements

Malignant cells are notorious for their ability to break away from a tumor, migrate to other seemingly targeted locations in the body, and establish new tumors, called metastases. The biochemical signals that guide tumor cell migration are poorly understood, but efforts to find those signals should receive a boost thanks to a new microfluidics device designed specifically to track how breast cancer cells move in response to chemical signals.
