Abstract:
Objective To explore a method to culture human aortic valvular interstitial cells and identify the phenotypes,to establish the cell model which would be used to study aortic valve diseases in vitro.Methods Normal aortic valves of the patient with acute Stanford A aortic dissection in Peking Union Medical College Hospital were preserved during the surgical operation.Human aortic valvular interstitial cells were isolated and amplified in vitro by modified collagenase digestion method.The cell phenotype was identified by the immunofluorescent staining.Results Human aortic valvular interstitial cells could be successfully isolated and amplified in vitro by modified collagenase digestion method,identified by positive staining of Vimention and α-SMA.Conclusions The cell model of human aortic valvular interstitial ceils could be successfully established in vitro by modified collagenase digestion method.The cell phenotype identification proved to meet the experimental requirements.So it could provide cellular foundations for the study of pathogenesis of degenerative aortic valve disease.
