Core Tip

Core tip: The development of platforms for investigating nutrient-gut interactions is critical to understanding how nutrients trigger the release of gut hormones and has the potential to yield novel targets for improved management of metabolic disorders. In addition to the use of endoscopic or surgical gut tissues or primary enteroendocrine cells, in vitro models now include enteroendocrine cell lines originating from rodent (STC-1 and GLUTag) or human (NCI-H716 and HuTo-80) intestinal tumours, and intestinal organoids differentiated from intestinal stem cells. The physiological relevance of these models has been challenged, but may be improved substantially by incorporating advanced biomedical techniques (e.g., microfluidic devices) into the culture system. These approaches have complemented clinical studies utilising intestinal intubation, often with integrated manometry and impedance recording, which have revealed gut region-specific responses to intraluminal contents. Newer clinical developments include the use of novel ingestible sensors.
