Unleashing Cell Power, Advancing Your Research

Digestion and absorption of carbohydrates occur primarily in the small intestine, where the breakdown of oligosaccharides and disaccharides tends to take place. The intestinal epithelium is the fastest-renewing tissue in humans, containing multiple cell types and a dynamic, multi-parameter microenvironment. Intestinal cells play a key role in the regulation of nutrient metabolism and energy balance and are a critical part of the regulation of intestinal sugar transport. Moreover, intestinal cell models accurately mimic human physiology, creating well-controlled and reproducible conditions for assessing cellular responses.

High-quality Intestinal Cells-based In Vitro Screening Service at CD BioGlyco

CD BioGlyco has long been committed to the development of Glycobiology Disease Models and has accumulated extensive experience in the field of In Vitro Glycobiology Disease Model Screening. Here, we provide our clients with a comprehensive and high-quality intestinal cells-based in vitro screening service.

• Establishing intestinal cell models
  We incubate the intestinal cells by placing them in a medium modified with monosaccharides, to which we add specific growth factors as well as amino acids. At the same time, we change the medium at determined intervals so that the intestinal cells divide in a certain ratio.
  For example, CaCo-2/TC7 cells are placed for growth in Eagle medium modified with D-glucose, which contains compounds such as penicillin, non-essential amino acids, and L-glutamine. This allowed the CaCo-2/TC7 cells to divide at a ratio of 1:20 and be used for subsequent experiments.
• Screening of intestinal cells
  The intestinal cells obtained from the culture are continued to be placed in a mixture of glycans for incubation, and we test the accumulation of glycans in the intestinal cells at different incubation times. To determine the specific accumulation of glycans, we test the intestinal cells using reverse transcription-polymerase chain reaction (RT-PCR) and detect the presence of expression of glycan-related genes in the cells.
  In addition, to adequately perform glycan screening, we make changes to the culture medium, mix the concentration of glycans and external conditions such as incubation time, and test the uptake and screening of glycans by intestinal cells.

• Our intestinal cell models offered to our clients herein include, but are not limited to, the following.
  • Caco-2 cell model
    The Caco-2 cell line, derived from human colorectal adenocarcinoma, is a mature in vitro model of human intestinal epithelial cells capable of absorbing and ingesting monosaccharides such as glucose, fructose, etc. CD BioGlyco provides clients with a mature Caco-2 cell model, as well as professional in vitro screening services based on the Caco-2 cell model.
  • HT-29 cell model
    The ability of HT-29 cells to express the properties of mature intestinal cells makes them an effective model for current research on the fundamental mechanisms controlling intestinal homeostasis and pathology, as well as for in vitro screening of glycobiology diseases. CD BioGlyco provides custom HT-29 cell model services with rich experience in the in vitro screening of glycobiology disease models.
  • Rat intestinal epithelial cells IEC-6 model
    IEC-6 is a cell line that exhibits epithelial morphology and can be affected by astragalus polysaccharides (APS) for proliferation, migration, and differentiation. CD BioGlyco utilizes scanning electron microscopy to assay the effects of polysaccharides on IEC-6 cell differentiation. We utilize the IEC-6 model to provide high-quality glycobiology disease screening services to our clients.
  • 3D intestinal epithelial cells model
    This cell line is a three-dimensional level cell model that accurately mimics human physiology, creating well-controlled and reproducible conditions for evaluating cellular uptake and translocation of glycans. CD BioGlyco combines multidisciplinary skills, to provide in vitro screening of glycobiology diseases based on the 3D intestinal epithelial cells model to clients.
