Summary
Researchers detail a method for isolating and culturing rat jejunum explants. These intestinal explants are valuable for in vitro studies of small intestine function and disease.
Area of Science:
- Gastroenterology
- Cell Biology
- Physiology
Background:
- The small intestine plays a critical role in digestion and nutrient absorption.
- In vitro models are essential for studying intestinal health and disease.
- Intestinal explants offer a comprehensive model containing diverse intestinal cell types.
Purpose of the Study:
- To describe a detailed procedure for isolating rat jejunum explants.
- To provide a protocol for culturing these explants in vitro.
- To facilitate research on small intestine function using explant models.
Main Methods:
- Isolation of intestinal explants from the rat jejunum.
- Establishment of in vitro culture conditions for explants.
- Short-term culture (up to 24 hours) of intestinal tissue.
Main Results:
- A reproducible method for obtaining viable rat jejunum explants was established.
- A protocol for maintaining explant viability and integrity in vitro for 24 hours was developed.
- The isolated explants retain key intestinal cell types.
Conclusions:
- Rat jejunum explants are a valuable tool for in vitro intestinal research.
- The described protocol enables the use of explants in short-term physiological and pathological studies.
- This method supports the development of advanced in vitro models for the small intestine.

Anatomy of the Intestines
87.1K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.

Techniques for Isolation of Pure Cultures
1.9K
Microorganisms are routinely cultured in the laboratory using various techniques to isolate, grow, and quantify them for further study. These methods rely on inoculating microorganisms into a suitable growth medium under aseptic conditions to prevent contamination. Depending on the objective, inoculation can involve direct transfer or the use of diluted bacterial suspensions as the inoculum.Streak-Plate Method for IsolationThe streak-plate method is a common technique for obtaining pure...

The small intestine is primarily responsible for digestion and nutrient absorption. It spans from the pyloric sphincter to the ileocecal valve and connects to the large intestine.
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique...

Large Intestine

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Histology of the Large Intestine
2.9K
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...
