NIH researchers successfully stop blood vessel, tumor growth in mice

(NIH/Eunice Kennedy Shriver National Institute of Child Health and Human Development) Scientists at the National Institutes of Health and other institutions have devised a new strategy to stop tumors from developing the new blood vessels they need to grow. Once thought to be extremely promising for the treatment of cancer, blocking molecules that stimulate new blood vessel growth (angiogenesis) has proven ineffective because tumor cells respond by producing more stimulatory molecules.
