The majority of studies have utilized aortic tissue as the source of cells. We present here a method for isolating and culturing smooth muscle cells of the rat superior mesenteric artery, an elasto-muscular vessel that is structurally and functionally different from the aorta. Cells were isolated from partially digested explants and characterized by immunochemical and biochemical techniques. Unlike cultured fibroblasts, the cultured cells stained positive for smooth muscle specific actin. The cells also produced laminin and type IV collagen in culture. This method provides a means for the isolation of large numbers of viable smooth muscle cells from the superior mesenteric artery which can be propagated in culture for in vitro study.</p>","PeriodicalId":77173,"journal":{"name":"In vitro cellular & developmental biology : journal of the Tissue Culture Association","volume":"29A 2","pages":"135-9"},"PeriodicalIF":0.0,"publicationDate":"1993-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02630944","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19456525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The number of colony forming cells per milliliter of culture medium and the frequency with which the culture medium is changed seemed to be the most critical factors regulating the emergence of induced and spontaneous variants. Increasing the number of cells plated so that of colony forming cells increase from 25 to 200 per ml, regardless of the dish size used, was associated with a 200-fold decline in the frequency of spontaneous variants and a 40-fold decline in X-ray-induced variants. Increasing the interval between medium changes from 3 to 7 days after the first week of culture was associated with a 10-fold decrease in the frequency of spontaneous variants. The frequency of spontaneous and induced variants is markedly less dependent on culture density at densities between 150 and 600 colony forming cells per ml. The type of medium used to establish primary cultures had little effect on the frequency of variants detected. Similarly, when assays were performed at densities in excess of 150 colony forming cells per ml the frequency of spontaneous and x-ray-induced variants was not affected by the absence of epidermal growth factor, increased levels of calcium (final concentration, 0.8 mM), or by removal of pyruvate from the selection medium.</p>","PeriodicalId":77173,"journal":{"name":"In vitro cellular & developmental biology : journal of the Tissue Culture Association","volume":"29A 2","pages":"120-6"},"PeriodicalIF":0.0,"publicationDate":"1993-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02630942","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19456524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
