(Kyoto University) Kyoto researchers have developed a new ‘tumor-on-a-chip’ device that can better mimic the environment inside the body, paving the way for improved screening of potential cancer fighting drugs. The device, has a 1 mm well at the center flanked by a series of 100 μm ‘microposts’. The culture is placed in the middle well, and cells that construct blood vessels are places along the microposts. Over a few days the vessels grow and attaches to the culture.
