Putting up a struggle against cancer
MIT scientists have discovered that cells lining the blood vessels secrete molecules that suppress tumor growth and keep cancer cells from invading other tissues, a finding that could lead to a new way to treat cancer.Elazer Edelman, professor in the MIT-Harvard Division of Health Sciences and Technology (HST), says that implanting such cells adjacent to a patient’s tumor could shrink a tumor or prevent it from growing back or spreading further after surgery or chemotherapy. He has already tested such an implant in mice, and MIT has licensed the technology to Pervasis Therapeutics, Inc., which plans to test it in humans. Edelman describes the work, which appears in the Jan. 19 issue of the journal Science Translational Medicine, as a “paradigm shift” that could fundamentally change how cancer is understood and treated. “This is a cancer therapy that could be used alone or with chemotherapy radiation or surgery, but without...
