Development of 3D liver spheroids
Human-based in vitro models are increasingly being used in the hepatology field. And in addition to the obvious ethical arguments, they offer several advantages over the classical animal models. One of them is the ability to perform mechanistic research at the molecular level in a well-controlled setting and reduce species differences. These liver-based in vitro models can range from simple monolayer cultures of hepatocytes to the liver-on-chips systems in which all liver cells are cultured in a 3D configuration on a microfluidic platform. Liver-based in vitro models must be selected on a case-by-case basis and should fit the purpose of the research, which might go from fundamental to translational research.
