To help researchers better understand the gut-brain axis MIT researchers have developed an organs-on-a-chip system that replicates interactions between the brain liver and colon. Senior scientist Hans Bouwmeester talks Medical Device Developments through the benefits of in-vitro models compared with traditional methods in assessing intestinal conditions.

Human Gut Microbiome On A Chip Nature Biomedical Engineering

In this study we show the application of a robust high throughput 3D gut-on-a-chip model for.

Gut on a chip. Conventional drug screening models often rely on simple 2D culture systems that fail to recapitulate the complexity of the organ situation. Ingber and co-authors gut-microbiome-on-a-chip consists of two channels separated by a permeable membrane with endothelial cells growing in the lower channel and epithelial cells growing in the. In many ways our brain and our digestive tract are deeply connected.

To assist researchers in further understanding gut physiology the intestinal microbiome and disease processes a novel technology primarily based on microfluidics and cell biology called gut-on-chip was developed to simulate the structure function and microenvironment of the human gut. Further applications of the gut-on-chip device This gut-on-a-chip provides a better model of the whole intestine than the previous Transwell chambers by recreating multiple dynamic physical and functional features of human intestine critical for its function as well as a controlled microfluidic environment amenable for transport absorption and toxicity studies. Generally gut-on-a-chip models have the potential to advance our understanding of the basic interactions found within the gut and lay the foundation for future applications in understanding pathophysiology developing drugs and personalizing medical treatments.

Here we describe a biomimetic human gut-on-a-chip microdevice composed of two microfluidic channels separated by a porous flexible membrane coated with extracellular matrix ECM and lined by human intestinal epithelial Caco-2 cells that mimics the complex structure and physiology of living intestine. Our Organ-on-a-Chip platform the OrganoPlate The OrganoPlate is a microfluidic 3D cell culture plate supporting up to 96 tissue models on a single plate. Gut-on-a-chip systems offer a new and powerful in vitro platform for studying human gut physiology pathology and pharmacology.

A gut-on-a-chip is a miniature version of the gut - the intestine - made from human gut-barrier cells placed into a chip a small device approximately the size of a USB stick that contains a fluid channel. Over the next five years the Gut-on-a-Chip market will register a xx CAGR in terms of revenue the global market size will reach US xx million by 2025. By the most conservative estimates of global Gut-on-a-Chip market size most likely outcome will be a year-over-year revenue growth rate of XX in 2020 from US xx million in 2019.

The OrganoPlate is based on the industry-standard 384-well plate for full compatibility with liquid handling- and readout equipment. These OoC systems will help advance the understanding and treatment of prevalent diseases such as inflammatory bowel disease IBD 55 and colorectal cancer 56. The Gut Chip is a microfluidic device composed of a clear flexible polymer that contains two parallel microchannels separated by a porous extracellular matrix membrane.

One channel is coated with human intestinal epithelial cells the other with human endothelial cells that mimic the blood vessel wall. As one of Micronit Microtechnologies customers Wageningen University Research uses the Netherlands-based companys platform for its gut-on-a-chip research. MIT researchers have developed an organs-on-a-chip system that replicates interactions between the brain liver and colon.

Gut-on-chip Healthcare has traditionally focused on one-size fits-all medication to treat populations instead of tailoring treatments to individual patients. Organs-on-a-chip system sheds light on how bacteria in the human digestive tract may influence neurological diseases. A common bottleneck in any drug development process is finding sufficiently accurate models that capture key aspects of disease development and progression.

A few gut-on-a-chip models have already been developed with adenocarcinoma-derived cell lines such as Caco-2 cells and HT-29 12 19 20 21 22. Using that system the researchers were able to model the influence that microbes living in the gut have on both healthy brain tissue and tissue samples derived from patients with Parkinsons disease. Martin Trapecar MIT In many ways our brain and our digestive.

A human gut-on-a-chip microdevice was used to coculture multiple commensal microbes in contact with living human intestinal epithelial cells for more than a week in vitro and to analyze how gut microbiome inflammatory cells and peristalsis-associated mechanical deformations independently contribute to intestinal bacterial overgrowth and inflammation. Because of the limited physiological relevance of. Cell culture medium is perfused through.

Feeling nervous may lead to physical pain in the stomach while hunger signals from the gut make us feel irritable. Organs-on-a-Chip Device Connects Gut Microbiome with Parkinsons Disease MIT researchers have developed an organs-on-a-chip system that replicates interactions between the brain liver and colon. By adapting the dimensions of the device to match the size of the human crypts and villi this gut-on-chip could be used in the near future to study the pathophysiology of the human gut.

By using epithelial cells andor fibroblasts extracted from colorectal cancer tissues it would be also possible to study the interplay between the stroma and cancer cells during tumor growth or invasion.
