Den nya kulturen metod 2 kan användas för en mängd olika tillämpningar, från transplantat av tillväxtfaktor som innehåller pärlor 3, till hela montera in situ hybridisering och hela montera immunohistokemi 4. Kultur över en 24-timmars period möjliggör kontinuerlig övervakning av embryonal utveckling i applikationer såsom tid förfaller celler rörelseanalys 5 eller övervakning av GFP innehåller electroporated konstruktioner 6.

method for culture of early chick embryos ex vivo (new culture)

Den kycklingembryo är ett värdefullt verktyg i studiet av tidiga embryonala utvecklingen. Dess öppenhet, tillgänglighet och enkel manipulation, gör det ett idealiskt verktyg för att studera bildning och mönstring av hjärnan, neuralrörsdefekter, somit och hjärta primordia. Tillämpningar av kycklingembryo kultur inkluderar elektroporering av DNA eller RNA konstruktioner för att analysera geners funktion, ympar av bestruket tillväxtfaktor pärlor som FGFs och BMP, liksom hela montera in situ hybridisering och immunhistokemi. Denna video visar de olika stegen i kycklingembryo kultur, det första är embryot explanterade i koksaltlösning. Då är embryot centrerad på ett glas ring. Membranen omger embryot lyfts längs väggarna i ringen. Ringen placeras sedan i en kultur maträtt som innehåller en pool av albumine. Kulturen skålen är förseglas och placeras i en fuktig kammare, där embryot odlas i upp till 24 timmar. Slutligen är embryot ut ur ringen, fasta och bearbetas för ytterligare ansökningar. En felsökningsguide presenteras också.
