Intestinal Organoids
Intestinal Organoids
Intestinal organoids are 3D microtissue models that recapitulate structures in the intestinal lumen and on the surrounding intestinal epithelium.
Most intestinal organoids are derived from primary intestinal tissue cultured in Matrigel domes with growth factors. Under these conditions, the intestinal cells self-arrange to form a single epithelial layer. The epithelium contains the essential cell populations found in the adult intestinal epithelium and is arranged in a crypt-villus structure. It can simulate essential intestinal functions, such as nutrient absorption and mucus secretion.
The cell composition and arrangement of the epithelium make intestinal organoids useful for studying intestinal cell biology, regeneration, differentiation, as wells as diseases phenotypes including effects of specific mutations, microbiome, or inflammation process.

At Molecular Devices, we have scaled up the expansion of healthy intestinal organoid lines with our 3D Ready™ Organoids. Quality-controlled organoids are manufactured at scale for high-throughput screening, leveraging proprietary bioreactor and bioprocess technology to produce reliable and predictive PDOs. Speak to an expert today to learn more about our assay-ready organoids and how they can accelerate your drug discovery and development efforts.
Using PDOS to treat cancer in FAP/MAP patients
The Inherited Tumour Syndromes Research (ITSR) group has been developing 3D organoid cell models to represent duodenal malignancy in FAP and MAP patients. In collaboration with Cellesce (now part of Molecular Devices) and Dr. Laura Thomas from Swansea University, these models have been refined for industrial use to facilitate drug discovery.
During the study, intestinal organoids were derived from intestine biopsy material from FAP and MAP patients, replicating the biology and appearance of duodenal adenomas or normal tissue. These matched pairs of diseased and healthy 3D organoid lines were used as representative models for research into the causes and effects of diseases and as a human-relevant platform for pre-clinical testing of potential treatments.
Automation of 3D intestinal organoid culture and imaging protocols
Here we demonstrate a workflow for the automation of 3D intestinal organoid culture. We developed automated methods for the seeding, and media exchange, as well as monitoring the development of intestinal organoids. In addition, this method allows automation of compound testing and evaluation of phenotypic changes.
Watch our short webinar with Dr. Oksana Sirenko, senior scientist as she discusses the protocols used to automate 3D intestinal organoids, developed from primary mouse intestinal cells cultured in Matrigel.

Intestinal organoids for automated screening assays. High content imaging and analysis of organoid morphology
In this application, 3D intestinal organoids were developed from primary mouse intestinal cells cultured in Matrigel. Methods for automated liquid handling were developed for cell seeding in Matrigel droplets and for media addition and exchanges. Six-week-old organoids were treated with various compounds followed by the live/dead assay and advanced image analysis to assess effects of treatment. In addition, methods to increase throughput, such as automated organoid assays and compound screening, are presented.
