Abstract:
Objective To find the features of cryo-injured infarcted model and the therapeutic effects of skeletal satellites cells(SCs) on myocardial infarction(MI).Methods SCs were implanted into the center of cryo-injured myocardium.Immunohistochemistry,confocal immunofluorescence double-labelling staining and transmission electron microscopy were used to study the state of SCs.Results After cryo-injured frontal wall of the left ventricle(LV) for approximately(15 s) by aluminium rod with(5 mm) in diameter,it made 43% weight of LV ischemia and 17% weight of LV infarcted.At 2nd week,injured area occured as transmural infarct.After transplantation,the implanted cells survived in large numbers.The transplanted cells proliferated remarkably at early phase and differentiated into many multinuclear myotubes after 2 weeks.Some of them developed into muscle fibers with better sarcomeres,but the gap junction was not formed between implanted cells and cardiac myocytes.Conclusions Cryo-injured infarcted model is a proper model to study myocardial infarction.Skelatal satellite cell transplantation will repair morphological structure partly of myocardial infarction area.
