Multi-organ-on-a-Chip: The Gut and Inflammatory Diseases

Alteration of the human gut is frequently linked to various diseases. While animal models are valuable tools for studying the interactions between hosts and microbes, there is still a need for a physiologically relevant in vitro gut model. This study presents the development of an integrated microfluidic platform that simultaneously incorporates features of both the gut and vascular systems. The gut chamber incorporates cellular layers resembling epithelial cells, while the vascular channel mimics blood vessel endothelial cells and incorporates shear stress forces relevant to blood flow. This multiorgan model provides a more accurate, in vitro representation of human physiological processes and offers new opportunities for studying gut-heart interactions and the impact of inflammatory diseases. The platform's versatility and scalability make it a promising tool for high-throughput screening, disease modeling, and precision medicine applications.
