NIH grants aim at creating 3-D tissue chips to help identify drug safety signals

Seventeen National Institutes of Health grants are aimed at creating 3-D chips with living cells and tissues that accurately model the structure and function of human organs such as the lung, liver and heart. Once developed, these tissue chips will be tested with compounds known to be safe or toxic in humans to help identify the most reliable drug safety signals - ultimately advancing research to help predict the safety of potential drugs in a faster, more cost-effective way.
