What is an in vitro screening model

In vitro screening models are tissue or cellular models constructed outside of a non-biological in vivo or shutdown experimental system. Such models are commonly used to study drug toxicology, pharmacokinetics, pharmacodynamics, and predictive toxicology, as well as for screening compounds and drugs with specific pharmacological activities. Some common models for in vitro screening include cell lines, primate cell lines, embryonic stem cells, microfluidic microarrays, tissue fragments, artificial biofilms, liver microarrays, brain microarrays, etc. In vitro screening models can streamline the research process, reduce animal experiments, improve data reliability, reduce experimental costs, and are an alternative approach focused on achieving humanity.
