analysis of schwann-astrocyte interactions using in vitro assays

Schwann hücreleri, omurilik yaralanması sonrasında onarım stratejileri yaygın olarak kullanılan hücre biridir. Schwann hücreleri, aksonal rejenerasyon salgılayan büyüme faktörleri 1,2 destekleyen ve çimlenme ve büyümeyi teşvik adezyon molekülleri 3 ve ekstraselüler matriks molekülleri 4 sağlayarak yeteneğine sahiptir . Buna ek olarak 5 yaralanma yerinde demyelinated aksonlar myelinate. Ancak, Schwann hücrelerinin nakli aşağıdaki implant sitesinden göç yoktur ve ev sahibi astrositler 6,7 ile karışmaz. Bu sonuç, Schwann hücreleri ve astrosit arasında keskin bir sınır oluşumu proksimale ve distale ana dokusu içine greft arka çıkmak için çalışıyor büyüyen aksonlar için bir engel oluşturmak. Schwann hücreleri ile temas Astrositler da hipertrofisi geçmesi ve inhibitör molekülleri 8-13 up-regüle. In vitro tayinlerde modeli Schwann hücre astrosit etkileşimleri kullanılmış olan ve hücresel davranışın altında yatan mekanizma anlaşılmasında önemli olmuştur. In vitro tayinlerde Bu sınır tayini, bir ko-kültür, sadece küçük bir boşluk iki hücre cephede ayıran farklı toprakları işgal her hücre tipi ile iki farklı hücre kullanılarak yapılır . Hücrelere bölmek ve göç gibi, hücresel iki cephede birbirlerine yakın ve nihayet çarpışır olsun. Bu davranış sınırında analiz edilecek iki hücre popülasyonlarının sağlar. Aynı tekniğin başka bir varyasyonu iki hücre popülasyonları kültür karışımı ve zamanla iki hücre tipleri ayırınız Schwann hücreleri ile birlikte birden fazla Schwann astrosit sınırları astrositler arasındaki adalar olarak bir araya clumped. Iki hücre tipleri etkileşim eğitim kullanılan ikinci tahlil, hücresel hareketi diğer hücre tipi tek tabaka 14,15 yüzey üzerinde takip edilebilir göç testtir . Bu testte ters lamel testinin yaygın olarak bilinir. Schwann hücreleri, küçük cam parçaları üzerinde kültür ve astrosit mono tabakaları yüzey üzerine yüzü aşağı gelecek şekilde ters düz ve göç lamel kenarında değerlendirilir. Her iki deneyleri hücresel dışlanma ve sınır oluşum yer altında yatan mekanizmaları inceleyerek etkili olmuştur. Bazı moleküllerin bu teknikleri N-Cadherins 15, Kondroitin Sülfat proteoglikanların (CSPGs) 16,17, FGF / Heparin 18, Efesliler / Ephrins 19 kullanılarak belirlendi. Bu makale, kademeli moda sınır tahlil ve göç tahlil tanımlamak ve meydana gelebilecek olası teknik sorunları aydınlatmak için niyetindedir.
