Chamber (image) Princeton University Caption A multi-institutional study including researchers from Princeton University's Physical Sciences-Oncology Center found that metastatic cancer cells are more aggressive and nimble than nonmalignant cells. The Princeton group used silicon-etched microchannels (above) to study the behavior and physical properties of cancer cells. In this device, metastatic cancer cells enter the narrow channels at one end and accelerate as they rapidly move down the channel. Such high motility is a hallmark of metastasis and also indicative of high glucose metabolism, another hallmark of cancer.
