Författarna vill tacka Josef LoTurco och Dennis Selkoe för bra diskussioner om denna teknik. Författarna tackar givarna av den amerikanska hälso-och sjukvård stiftelse för att stödja denna forskning.

Den grundläggande protokoll för i livmodern elektroporering har beskrivits i detalj i en annan JUPITER artikeln från Kriegstein lab 1, 2. Denna teknik var ursprungligen beskrivits i Osumi labb 3 och vårt protokoll bygger på en utvecklad i LoTurco lab 4. Vi kommer att tillhandahålla en översikt över våra protokoll för i livmodern elektroporering av råtta embryon, med fokus på de viktigaste detaljerna, följt av en beskrivning av våra protokoll som gäller <e...

in utero electroporation followed by primary neuronal culture for studying gene function in subset of cortical neurons

In vitro-studier av primära neuronala kulturer möjliggör kvantitativa analyser av neurite utväxt. För att studera hur genetiska förändringar påverkar neuronala processen utväxt, shRNA eller cDNA konstruktioner kan införas i primär nervceller via kemiska transfektion eller viral transduktion. Men med primär kortikala celler, är en heterogen grupp av celltyper (glutamaterg nervceller från olika lager, hämmande nervceller, gliaceller) transfekterade med dessa metoder. Användningen av i livmodern elektroporering att införa DNA-konstruktioner i den embryonala gnagare cortex tillåter vissa grupper av celler som utgör målgrupp: medan elektroporering av tidiga embryonala cortex mål djupa lagren av hjärnbarken, mål elektroporation på sena embryonala tidpunkter mer ytliga lager. Vidare differential placering av elektroder över huvudet på enskilda embryon resulterar i att rikta dorsal-mediala kontra ventral-laterala områden av hjärnbarken. Efter elektroporation kan transfekterade celler dissekeras ut, dissocierade, och pläterade in vitro för kvantitativ analys av neurite utväxt. Här ger vi en steg-för-steg metod för att kvantitativt mäta neuronala processen utväxt i delmängder av kortikala celler. Den grundläggande protokoll för i livmodern elektroporering har beskrivits i detalj i två andra JUPITER artiklar från Kriegstein lab 1, 2. Vi kommer att ge en översikt över våra protokoll för i livmodern elektroporering, med fokus på de viktigaste detaljerna, följt av en beskrivning av våra protokoll som gäller i livmodern elektroporering till att studera geners funktion i neuronala processen utväxt.

In utero Electroporation followed by Primary Neuronal Culture for Studying Gene Function in Subset of Cortical Neurons

I livmodern elektroporation är en värdefull metod för transfecting neuronala stamceller in vivo. Beroende på placering av elektroderna och utvecklingsmässiga tidpunkterna för elektroporation kan vissa delmängder av kortikala celler riktas. Riktade celler kan sedan analyseras in vivo eller in vitro för effekterna av genetiska förändringar.
