The interstitial cells of Cajal (ICC) drive rhythmic pacemaking contractions in the gastrointestinal system. The ICC generate pacemaking signals by membrane depolarizations associated with the release of intracellular calcium (Ca(2+)) in the endoplasmic reticulum (ER) through inositol-trisphosphate (IP3) receptors (IP3R) and uptake by mitochondria (MT). This Ca(2+) dynamic is hypothesized to ge...
Interstitial cells of Cajal (ICC) undergo marked morphological changes on contraction of the musculature, making it essential to understand properties of mechanosensitive ion channels. The whole cell patch-clamp technique was used to identify and to characterize volume-activated Cl- currents in ICC cultured through the explant technique. Hypotonic solutions (approximately 210 mosM) activated an...
Aim: To explore the emodin’s toxicity and action mechanism on the function of interstitial cells of Cajal (ICC) cultured in vitro. Methods: ICC of KM mouse was cultured in vitro. The minimum toxicity concentration and critical time points of emodin were investigated with Uniform Design methodology and MTT assay. The cell enzymology assay and enzyme immunoassay (EIA) were applied to observe the ...
It is postulated that the electric waves of the gut are generated by interstitial cells of Cajal (ICC). We hypothesized the presence of ICC in the rectum as initiating the rectal electric activity. The current study investigated this hypothesis. Two rectal specimens were taken from healthy areas of excised rectum of 22 rectal cancer patients (age 44.6+/-.2 SD years, 12 men, 10 women). The study...
The paper reviews the present-day knowledge on the origin, location, morphology, function, and identification of interstitial cells of Cajal (ICC). ICC include several types of mesenchymal cells, spindle-shaped or stellate, found within the musculature of the gastrointestinal tract. Some types of ICC act as pacemakers of the intestinal musculature, while others are implicated in the modulation ...
BACKGROUND & AIMS Interstitial cells of Cajal (ICC) closely associate with nerves and smooth muscles to modulate gut motility. In the ICC microenvironment, although the circulating hormones/factors have been shown to influence ICC activities, the association between ICC and microvessels in the gut wall has not been described. We applied three-dimensional (3D) vascular histology with c-kit stain...
