imaging cell shape change in living drosophila embryos

Gelişmekte olan Drosophila melanogaster embriyo konfokal görüntüleme yaşamak için son derece müsait olan hücre şekil değişiklikleri bir dizi uğrar. Hücre sinek şekil değişiklikleri, yüksek organizmalarda benzer olup, doku morfolojilerinden sürücü. Yani, birçok durumda, yaptıkları çalışmada insan hastalığı (Tablo 1) 1-5 anlamak için doğrudan etkisi vardır. Hücre alt ölçekte, bu hücre şekil değişiklikleri, gen ekspresyonu, sinyal iletimi, hücre polarite, iskelet remodeling ve membran ticareti değişen faaliyetlerinin ürünüdür. Böylece, Drosophila embriyo doku morfolojilerinden ile ilgili olarak hücre şekil değişiklikleri değerlendirmek bağlamında sadece sağlar, ama aynı zamanda şekil hücreleri, alt-hücresel faaliyetler çalışma tamamen fizyolojik bir ortam sunmaktadır. Burada açıklanan protokol görüntü cellularization denilen özel bir hücre şeklini değiştirmek için tasarlanmıştır. Cellularization, dramatik plazma membran büyüme bir süreç olduğunu ve sonuçta hücresel blastodermin sinsityal embriyo dönüştürür. Interfaz mitotik döngüsü 14 olduğunu, plazma zarı aynı anda birincil epitel hücrelerinin bir sayfa oluşturmak için her ~ 6000 cortically demirlemiş çekirdeklerinin etrafında invaginates. Sayaç önceki önerileri, cellularization Miyozin-2 kontraktilite 6 tarafından yönlendirilen değil, ancak bunun yerine büyük ölçüde iç mağazaları 7 zarının ekzositoz tarafından körüklenen . Böylece, cellularization sitokinez veya enine-borucuk (T-tübül) kas morfolojilerinden olarak plazma zarı invajinasyon veya genişleme gerektiren hücre şekil değişiklikleri sırasında membran kaçakçılığı eğitimi için mükemmel bir sistem. Bu protokol sinek embriyo diğer hücre şekil değişiklikleri görüntüleme kolayca uygulanır ve sadece embriyo toplama aşamasında, değiştirme veya belirli bir oryantasyon (Tablo embriyo monte etmek için &quot;embriyo tutkal&quot; olarak hafif uyarlamalar gerektirir olduğunu unutmayın 1) 8-19. Tüm durumlarda, iş akışı temelde aynıdır (Şekil 1). Klonlama ve Drosophila transgenesis için standart yöntemler, Yeşil Floresan Protein (GFP) veya türevleri erimiş bir ilgi protein ifade istikrarlı sinek stokları hazırlamak için kullanılan ve bu sinekler, embriyo yenilenebilir bir kaynak sağlamak . Alternatif olarak, floresan proteinleri / problar doğrudan sinek embriyolara 9-10 basit mikro-enjeksiyon teknikleri ile tanıtıldı. Sonra, gelişimsel bir olay ve görüntülü olarak hücre şekil değişikliği göre, embriyolar toplanan ve diseksiyon mikroskobu morfolojisi tarafından sahnelenen, ve son olarak konumlandırılmış ve zaman atlamalı bir konfokal mikroskop görüntüleme için monte edilmiş.
