the c. elegans intestine as a model for intercellular lumen morphogenesis and in vivo polarized membrane biogenesis at the single-cell level: labeling by antibody staining, rnai loss-of-function analysis and imaging

Мультиклеточные трубы, базовых единиц всех внутренних органов, состоят из поляризованные эпителия или эндотелиальных клеток, верхушечный мембран подкладки люмен и базолатеральной мембраны, связавшись с друг друга и/или внеклеточного матрикса. Как эта асимметрия отличительные мембрана создана и поддерживается в течении морфогенеза орган все еще нерешенный вопрос о клеточной биологии. Этот протокол описывает C. elegans кишечника как модель для анализа биогенеза поляризованной мембраны при морфогенеза трубки, с упором на апикальной мембраны и Люмене биогенеза. C. elegans однослойные двадцать клеток кишечного эпителия аранжирован в простой на двусторонней основе симметричных трубки, позволяющих анализ на уровне одной ячейки. Поляризацию мембраны происходит одновременно с поляризованными деление клеток и миграции в раннем эмбриогенезе, но de novo поляризованных мембраны биогенеза продолжается в течение всего роста, когда клетки больше не размножаются и двигаться. Последняя настройка позволяет отделить субцеллюлярные изменения, которые одновременно посредником эти различные поляризационные процессы, трудно отличить в большинстве моделей полярности. Верхушечный, базолатеральной мембраны-, соединительной-, цитоскелета- и endomembrane компонентов может быть помечены и отслеживается GFP синтез белков на протяжении развития или оценены в situ Пятнать антитела. Вместе с организма генетических универсальность C. elegans кишечника таким образом обеспечивает уникальный в vivo модель для визуального, развития и молекулярно генетический анализ поляризованной мембраны и биогенеза трубки. Конкретные методы (все стандартные) описанные здесь включают как: этикетка кишечных субцеллюлярные компоненты путем пятнать антитела; анализ генов, участвующих в поляризованной мембраны биогенеза исследования потери функции адаптированы к обычно основные tubulogenesis генов; оценить полярности дефектов на разных этапах развития; интерпретировать фенотипов эпифлуоресцентного, дифференциальной помехи контраст (ОПК) и confocal микроскопии; определить дефекты. Этот протокол может быть адаптирована для анализа любого из зачастую весьма сохранены молекул, участвующих в эпителиальных полярности, мембраны биогенеза, трубки и Люмене морфогенеза.

Этот протокол описывает молекулярно анализировать и визуализировать поляризованной мембраны биогенеза и Люмене морфогенеза в C. elegans ЖКТ, на одну ячейку и субклеточном уровне. Двадцать клетки однослойная C. elegans кишечника образуется режиссер деление клеток и...

Прозрачный C. elegans кишечника может служить в качестве «в vivo ткани палата» для изучения apicobasal мембраны и Люмене биогенеза на одну ячейку и субклеточном уровне во время многоклеточных tubulogenesis. Этот протокол описывает, как сочетать стандартные маркировки, потеря функции генетических/RNAi и микроскопических подходов к вскрыть этих процессов на молекулярном уровне.
