Flipping the switch on tumor growth

Time-lapse imaging can reveal tell-tale changes in cellular behaviors associated with tumor growth.

Without a blood supply, a tumor can remain dormant and harmless. But new blood vessel growth from an existing vessel, a process called angiogenesis, is a hallmark of both benign and malignant tumors. During angiogenesis, blood vessels invade tumors and activate them, fueling their growth.

Now, Marsha A. Moses, PhD, who directs the Vascular Biology Program at Boston Children’s Hospital, and members of her laboratory have revealed that a specialized imaging system can detect changes in cell behaviors. These changes predict when tumors are leaving a state of dormancy and becoming more likely to grow.
