In drug development, preclinical testing of hepatotoxicity is currently limited in its ability to provide key, predictive data. The reproducibility of human primary hepatocytes is low, and functionality is quickly lost in culture. Cellartis Enhanced hiPS-HEP is a highly homogenous hepatocyte population derived from human iPS cells. With low error margins and high enzyme expression, this new system has the potential to vastly improve patient safety. That's Good Science!
