Cellartis enhanced hiPS-HEP v2 kits provide an inexhaustible supply of mature hepatocytes derived from human induced pluripotent stem (hiPS) cells. hiPS-HEP cells have functional drug-metabolizing machinery over a 14-day assay window, making them ideal for in vitro drug discovery, drug metabolism, and toxicology-related studies. Mature, robust metabolic features support metabolic disease modeling. The user-friendly kit format includes complete media and components for long-term assays. Compared to other hepatic cell models, these cells survive longer in culture, which enables a longer assay window in chronic-toxicity experiments and for metabolic disease modeling.
