Renewal of Intestinal Stem Cells

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the goblet,...

Mucosal Barrier of the Stomach

Mucosal Barrier of the Stomach

The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Barrett Esophagus-I: Introduction

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Barrett Esophagus-II: Clinical Manifestations and Management

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

Gastritis-II: Pathophysiology

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Gastritis II: Pathophysiology

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...

Paneth cells in Barrett's esophagus.

D S Schreiber, M Apstein, J A Hermos

Gastroenterology

|June 1, 1978

Summary

Paneth cells, typically found in the intestine, were identified in esophageal biopsies. Their presence alongside goblet cells suggests specialized columnar epithelium in the esophagus represents intestinal metaplasia.

Area of Science:

Gastroenterology
Histopathology
Cell Biology

Background:

Barrett's esophagus is a condition where the esophageal lining changes.
Specialized columnar epithelium is a subtype observed in Barrett's esophagus.
Paneth cells are specialized epithelial cells normally found in the small intestine.

Observation:

Paneth cells were identified in esophageal biopsies from patients with specialized columnar Barrett's epithelium.
These esophageal Paneth cells exhibited characteristics identical to intestinal Paneth cells via microscopy and histochemistry.
Further review confirmed Paneth cells in additional cases of esophageal specialized columnar epithelium.

Findings:

The presence of Paneth cells in the esophagus, alongside goblet cells, was confirmed.

Morphological and histochemical analyses showed esophageal Paneth cells resemble their intestinal counterparts.

This indicates a potential for intestinal differentiation within the esophageal epithelium.

Implications:

The findings suggest that specialized columnar epithelium in the esophagus may represent a form of advanced intestinal metaplasia.
This could have implications for understanding the development and progression of Barrett's esophagus.
Further research may explore the functional role of these intestinalized cells in the esophagus.
