豚鼠膀胱Cajal样间质细胞钙震荡特性
Calcium Oscillation Characteristics of Interstitial Cells of Cajal in Guinea Pig Bladder
摘要
Abstract
Objective:To ascertain the spontaneous and cyclical calcium oscillation in Cajal-like interstitial cells of Cajal in the bladder of adult guinea-pig.Method:The V-type enzyme collagenase was used to separate primary cells from myoblast of the preparation muscle tissue,primary cells were cultured.Using fluo-4 AM dye the Cells.The change of calcium fluorescence intensity was recorded with laser scanning microscope imaging. The changes of the intracellular calcium concentration was on behalf with the Fluorescence intensity.Result:The Cajal-like interstitial cells maintained its inherent characteristics by primary cultivation.We could see that the cell had a spindle cell body with two slender bipolars.In the Cajal-like interstitial cells of bladder:there were 2 different types of spontaneous calcium,small irregular calcium oscillation and large oscillation slow calcium oscillation.The second type of calcium oscillation was completely different from those of smooth muscle cells.Conclusion:We have confirmed the existence of the spontaneous calcium oscillation in the Cajal-like interstitial cells in the bladder of adult guinea-pig,that like the pacemaker cells of interstitial cells of Cajal in the digestive tract.Implying that part of the Cajal-like interstitial cells may be the pacemaker cells of contraction or activity of bladder.关键词
