Abstract

Objective: For in vitro tissue engineering in urology, stem cells are commonly isolated from tissue specimensobtained during open or endoscopic surgery. Within the context of the present study our aim was toisolate cells from human urine by an alternative and safe technique rather than using the indicated method.Material and methods: After human urine samples had been collected from young and healthy donorsvia urethral catheterization, cells were precipitated by centrifugation and cultured. Following this isolationprocedure, cells were characterized by immunocytochemical method using specific antibodies.Results: When these cells were characterized by immunocytochemical methods using specific antibodiessome of them were positive for mesenchymal stem cell marker CD90 while the others were labelled withurothelial marker cytokeratin 7. When all these results were taken into consideration, urothelial cells togetherwith stem cells were observed in the urine- derived cell population.Conclusion: According to the results obtained from this study human urine may be preferred as an alternativestem cell and urothelial cell source in that this method is and easily reproducible non-invasive method

Özet

Amaç: Üroloji alanındaki in vitro doku mühendisliği uygulamalarında kök hücreler, yaygın olarak açık ya da endoskopik ameliyatlardan elde edilen doku biyopsilerinden izole edilmektedirler. Bu çalışma kapsamında, belirtilen yöntem yerine daha güvenli bir alternatif teknikle insan idrarından hücre izole edilmesi amaçlanmaktadır. Gereç ve yöntemler: İnsan idrar örnekleri, üretral kateter aracılığyla genç ve sağlıklı bireylerden toplandıktan sonra hücreler, santrifigasyon yöntemiyle çöktürülmüş ve kültür ortamına alınmışlardır. Bu izolasyonun ardından hücreler, immünositokimyasal yöntemle spesifik antikorlar kullanılarak karakterize edilmişlerdir. Bulgular: Bu hücreler immünositokimyasal yöntemlerle ve spesifik antikorlar aracılığıyla karakterize edildiğinde, elde edilen hücre populasyondaki bazı hücrelerin mezenkimal kök hücrelerin CD90 markörü açısından pozitif olduğu bazılarının ise ürotelial hücre markörü olan sitokeratin 7 ile işaretlendiği belirlenmiştir. Bu sonuçlar birlikte ele alındığında, idrardan elde edilen hücre populasyonunda ürotelial hücrelerin ve kök hücrelerin birlikte yer aldıkları gözlenmiştir. Sonuç: Bu çalışmada elde edilen sonuçlara göre, uygulanan yöntemin kolaylıkla tekrarlanabilir ve invaziv olmamasından dolayı insan idrarı, alternatif kök hücre ve ürotelial hücre kaynağı olarak tercih edilebilir bir kaynaktır
