IRE1β negatively regulates IRE1α signaling in response to endoplasmic reticulum stress [PDF]

open access: yes, 2020
IRE1β is an ER stress sensor uniquely expressed in epithelial cells lining mucosal surfaces. Here, we show that intestinal epithelial cells expressing IRE1β have an attenuated unfolded protein response to ER stress.

Drivers of Transcriptional Variance in Human Intestinal Epithelial Organoids [PDF]

open access: yes, 2021
Human intestinal epithelial organoids (enteroids and colonoids) are tissue cultures used for understanding the physiology of the human intestinal epithelium.

Low-Level Mouse DNA in Conditioned Medium Generates False Positive Cross-Species Contamination Results in Human Organoid Cultures

open access: yesFrontiers in Cell and Developmental Biology, 2020
Cell line authentication is critical for preventing the use of mixed or misidentified cell lines in research. Current efforts include short tandem repeat (STR) analysis and PCR-based assays to detect mixed species cultures.

Enterohemorrhagic Escherichia coli Reduces Mucus and Intermicrovillar Bridges in Human Stem Cell-Derived ColonoidsSummary

open access: yesCellular and Molecular Gastroenterology and Hepatology, 2016
Background & Aims: Enterohemorrhagic Escherichia coli (EHEC) causes over 70,000 episodes of foodborne diarrhea annually in the United States. The early sequence of events that precede life-threatening hemorrhagic colitis and hemolytic uremic syndrome is ...

Single Cell Analysis of Human Colonoids Exposed to Uranium-Bearing Dust. [PDF]

open access: yesEnviron Health Perspect
Uranium exposure remains an important environmental legacy and physiological health concern, with hundreds of abandoned uranium mines located in the Southwestern United States largely impacting underserved indigenous communities. The negative effects of heavy metals on barrier permeability and inhibition of intestinal epithelial healing have been ...

Fecal Luminal Factors from Patients with Gastrointestinal Diseases Alter Gene Expression Profiles in Caco-2 Cells and Colonoids [PDF]

open access: yes, 2022
Previous in vitro studies have shown that the intestinal luminal content, including metabolites, possibly regulates epithelial layer responses to harmful stimuli and promotes disease.

Co‐Culture System of Human Enteroids/Colonoids with Innate Immune Cells

open access: yesCurrent Protocols in Immunology, 2020
AbstractHuman intestinal enteroids derived from adult stem cells offer a relevant ex vivo system to study biological processes of the human gut. They recreate cellular and functional features of the intestinal epithelium of the small intestine (enteroids) or colon (colonoids) albeit limited by the lack of associated cell types that help maintain tissue

Differentiation of human colon tissue in culture: Effects of calcium on trans-epithelial electrical resistance and tissue cohesive properties.

open access: yesPLoS ONE, 2020
Background and aimsHuman colonoid cultures maintained under low-calcium (0.25 mM) conditions undergo differentiation spontaneously and, concomitantly, express a high level of tight junction proteins, but not desmosomal proteins.

Mechanisms of Intestinal Epithelial Barrier Dysfunction by Adherent-Invasive Escherichia coli. [PDF]

open access: yes, 2016
Pathobiont expansion, such as that of adherent-invasive Escherichia coli (AIEC), is an emerging factor associated with inflammatory bowel disease. The intestinal epithelial barrier is the first line of defense against these pathogens.

Concise Review: The Potential Use of Intestinal Stem Cells to Treat Patients With Intestinal Failure. [PDF]

open access: yes, 2016
: Intestinal failure is a rare life-threatening condition that results in the inability to maintain normal growth and hydration status by enteral nutrition alone.
