Intestinal Motility

Intestinal motility is the coordinated movement of the digestive tract that mixes intestinal contents and propels them toward the colon, supporting digestion and nutrient absorption. It arises from rhythmic contractions of smooth muscle, shaped by the enteric nervous system, autonomic signals, hormones, and pacemaker activity from interstitial cells of Cajal; segmentation mainly mixes contents, while peristalsis moves them forward. Studying intestinal motility helps explain how the gut regulates transit, secretion, and absorption and how these functions change in conditions such as constipation, diarrhea, and intestinal obstruction. It also supports research into gastrointestinal physiology, pharmacology, and treatments for motility disorders.

Recently available video recording and spatiotemporal mapping (STmap) techniques make it possible to visualize and quantify both propagating and mixing patterns of intestinal motility. The goal of this protocol is to explain the generation and analysis of STmaps using the GastroIntestinal Motility Monitoring (GIMM) system.

Postoperative ileus (POI) is a complication of abdominal surgery leading to increased morbidity and a prolonged hospital stay. Because prophylactic or therapeutic strategies are lacking intensified research is necessary. Therefore we established a standardized and feasible mouse model to investigate the pathophysiology of POI and to study potential therapeutic options.

This article describes a video imaging technique and high-resolution spatiotemporal mapping to identify changes in the neural regulation of colonic motility in adult mice. Subtle effects on gastrointestinal (GI) function can be detected using this approach in isolated tissue preparations to advance our understanding of GI disease.

An Introduction to Cell Motility and Migration

0 Views •

2023

Cell motility and migration play important roles in both normal biology and in disease. On one hand, migration allows cells to generate complex tissues and organs during development, but on the other hand, the same mechanisms are used by tumor cells to move and spread in a process known as cancer metastasis. One of the primary cellular machineries that make cell movement possible is an intracellular network of myosin and actin molecules, together known as “actomyosin”, which creates a...
