Gut-on-a-Chip Model Introduction

The gut microbiome orchestrates human intestinal cells and a rich microbial consortium, which is a critical human biological function. Creative Biolabs' attempts on studying in gut-on-a-chip model have focused on simulating the physiology of the gut, an organ with a distinct cellular composition featuring a plethora of microbial and human cells that mutually mediate critical body functions. Our innovative approaches to model fluid flow, mechanical forces, and oxygen gradients recreate the gut physiological systems. Our Gut-on-a-chip Model will advance your understanding of the basic interactions found within the gut and lay the foundation for future applications in understanding physiology, developing drugs, and personalizing medical treatments.

Introduction of Our Gut-on-a-chip Model

The body of our gut-on-a-chip model houses the channels or chambers and any other embedded elements such as sensors, electrodes, or valves. The model is optically transparent and gas permeable to allow for facile imaging and observation as well as to facilitate the diffusion of gases such as oxygen (O2) and carbon dioxide (CO2).

Comparisons with Conventional Models

Creative Biolabs' gut-on-a-chip model differs from previous models by not only integrating primary human macrophages together with IEC, but also by inducing an inflammatory state of the epithelium similar to the one observed in inflammatory bowel disease (IBD) patients. Our gut-on-a-chip model represents all differentiated cell types present in the human intestinal organoids.

Direct Experimentation on Human Subjects Animal Models 2D Conventional Models Gut-on-a-chip Model
× No accessibility of the GI tract
× Colonoscopy-invasive and lacked cellular-level resolution.
× High cost
× Ethical issues.
× Lack of high-quality real-time visualization capabilities.
× Poor correlation to real issue physiology due to their planar geometry. √ Leverage the differentiation and self-organization ability of stem cells to construct organ-mimicking tissues.
√ Natural cellular structure.
√ Incompatible with modeling transport processes and the organ's internal microenvironment.

Applications of Our Gut-on-a-chip Model

  • Disease Modeling: In gut-on-a-chip systems, multiple cellular or environmental variables of relevance can be evaluated, and physiological effects derived from each modulation can be characterized in terms of cellular morphology, multi-omics profile, tissue barrier function, cytokine releases, and other factors.
  • Drug Metabolism: Our Gut Chip devices can fill the existing voids in drug discovery, for instance, particularly apt for developing therapies for GI disorders, as they can simulate both the disease and the treatment strategy at once.
  • Industrialization: In the biomedical industry particularly, the demand for a robust in vitro platform has been growing considering the present lengthy, complicated, and time-consuming drug discovery process. Our gut-on-a-chip has fulfilled the need for the development of composite devices to mimic broader physiological features.

Creative Biolabs' Advantages

Creative Biolabs is experienced in developing organoid models and continuously improving our products. Our gut-on-a-chip model can tackle two critical limitations of the previous in vivo models simultaneously: (i) the inability to capture the function in three dimensions; and (ii) the modeling of physiochemical environmental cues which are key determinants of myriad physiological processes. The advent of our gut-on-a-chip technology allows you to separately control physical and mechanical factors (e.g., fluid flow) as well as cellular components to better understand and model intestinal homeostasis and diseases of the gastrointestinal tract such as IBD.
