Ce protocole a été développé par notre travail au sein et en collaboration avec les laboratoires de Paul Martin et Antonio Jacinto. Nous remercions le Centre Stock Bloomington pour son excellent service et la communauté drosophile de continuer à partager les lignes voler. BS est actuellement financé par une subvention du BBSRC projet. WW est financé par une bourse du Wellcome Trust en développement de carrière.

Préparation <ol><li> Obtenir appropriés lignes drosophile contenant une hémocytes spécifiques Gal4 conducteur (p. ex srp-Gal4 2) et un journaliste codées génétiquement fluorescent sous SAMU de contrôle (par exemple, UAS-GFP). Les mouches homozygotes pour srp-Gal4, UAS-GMA 3 ou CRQ-Gal4, UAS-GFP 4, 5 sont particulièrement utiles à des fins d&#39;imagerie (nb GMA est la GFP fusionnée au domaine de liaison de l&#39;actine-moésine); ...

Les éléments les plus importants de cette procédure sont à la sélection d&#39;embryons sains avec hémocytes clairement étiquetés et de les monter avec soin sans les endommager. Une fois que les embryons sont des halocarbures dans l&#39;huile ils sont résistants à la déshydratation et une fois montée peut être imagée pendant plusieurs heures. Dans nos mains, nous pouvons hémocytes d&#39;image pendant trois heures, avec une déshydratation négligeable de l&#39;embryon ou du photo-dommages évidents, en pre...

live imaging of drosophila melanogaster embryonic hemocyte migrations

Beaucoup de migration cellulaire des études utilisant l&#39;adresse<em&gt; In vitro</emMéthodes&gt;, alors que l&#39;environnement physiologiquement pertinente est celle de l&#39;organisme lui-même. Nous présentons ici un protocole pour le montage<em&gt; Drosophila melanogaster</em&gt; Embryons et ultérieures imagerie en temps réel des hémocytes marqués par fluorescence, les macrophages embryonnaire de cet organisme. En utilisant le système UAS-Gal4<sup&gt; 1</sup&gt; Nous conduisons l&#39;expression d&#39;une variété d&#39;organismes génétiquement codés, des marqueurs de fluorescence marqués dans les hémocytes de suivre leur dispersion à travers le développement de l&#39;embryon. Après la collecte d&#39;embryons au stade de développement souhaité, le chorion externe est enlevée et les embryons sont ensuite montés dans l&#39;huile d&#39;halocarbures entre un hydrophobe, perméable aux gaz de membrane et une lamelle de verre pour l&#39;imagerie en direct. En plus de paramètres brute migrateurs tels que la vitesse et la directivité, de l&#39;imagerie haute résolution couplée à l&#39;utilisation des reporters fluorescents de F-actine et les microtubules peuvent fournir des informations plus détaillées concernant la dynamique de ces composants du cytosquelette.
