Abstract
Traditional in vitro intestinal model systems frequently fail to accurately replicate human intestinal physiology for absorption, distribution, metabolism, excretion, and toxicity (ADMET) assessments. These limitations, coupled with the growing demand for faster drug discovery and high-throughput screening capabilities, have refined more physiologically relevant models. Recent advancements have led to the development of cell-based intestinal systems that better reflect in vivo conditions, ranging from monolayer and coculture models to complex three-dimensional (3-D) cell culture systems, microfluidic devices, and bioengineered models. This review provides a comprehensive overview of current progress, ongoing challenges, and future directions in developing and applying human in vitro intestinal models for chemical testing.
期刊介绍:
The American Journal of Physiology-Gastrointestinal and Liver Physiology publishes original articles pertaining to all aspects of research involving normal or abnormal function of the gastrointestinal tract, hepatobiliary system, and pancreas. Authors are encouraged to submit manuscripts dealing with growth and development, digestion, secretion, absorption, metabolism, and motility relative to these organs, as well as research reports dealing with immune and inflammatory processes and with neural, endocrine, and circulatory control mechanisms that affect these organs.
