Her præsenterer vi to forskellige protokoller til kultur primærelementer fra enten 2 dpf zebrafisk embryoner eller voksen zebrafisk hjernen.
Forberedelse af primære cellekulturer fra 2 dpf zebrafisk er relativt let at udføre for nogen med erfaring i basale celle kultur teknikker. Men for at opnå god og reproducerbare resultater, et tilstrækkeligt antal embryoner som udgangspunkt materiale er afgørende (100 er et minimum). Under en forhøjelse af embryonerne, skal alle mulige kilder til ...

Zebrafisk (Danio rerio, D. rerio) er en populær model hvirveldyr for talrige områder af grundlæggende og biomedicinsk forskning1. Zebrafisk embryoner udvikler hurtigt ex utero, er gennemsigtige, og pasform under et mikroskop, hvilket giver gode forudsætninger for at studere hvirveldyr udvikling i en levende organisme. På grund af den genetiske sporbarhed af zebrafisk2oprettet mange stabile transgene reporter linjer med celle type-specifikke udtryk for forskellige fluorescerende markører giver mulighed for observation af specifikke cellepopulationer. Zebrafisk samfundet tilbyder en bred vifte af såkaldte Gal4-driver linjer, som bærer en transgen udtrykker den syntetiske Kal4TA4 (eller KalTA3-ækvivalent-GalFF) genet med Gal4-DNA-bindende domæne af gær smeltet til viral transcriptional aktivering domæner under kontrol af celle typespecifikke smagsforstærkere. Disse driver linjerne krydses effektor linjer, som bærer transgener bestående af en defineret opstrøms aktiverende sekvens (UAS) smeltet til en reporter gen. Kal4TA4 protein binder sig til elementet UAS, dermed aktivering celle type-selektiv udtryk for reporter gen3,4. Denne tilgang giver mulighed for meget forskelligartede kombinatorisk undersøgelser af næsten alle tilgængelige enhancer og reporter elementer i dobbelt-transgene dyr.
Men dybdegående live imaging med fokus på individuelle celler eller deres subcellulært indhold er begrænset i et hele og konstant skiftende embryo. For at løse specifikke celle biologiske spørgsmål med højeste opløsning, er brugen af cellekulturer ofte at foretrække. Nogle cellelinjer af zebrafisk eksisterer, men de betragtes som stærkt valgte5,6,7 og deres formering er ofte tidskrævende. Derudover er alle tilgængelige cellelinjer fibroblast afledt, begrænse eksperimenter ved hjælp af cellekultur til én type af celler. Derfor, vi etableret både en effektiv og nem at bruge protokollen for at forberede primærelementer direkte fra zebrafisk embryoner og voksen zebrafisk hjernen, sammen med metoder til at øge levetiden af kulturen og at udvide mangfoldigheden af dyrkede celletyper. Derudover præsenterer vi en procedure for at transfect primære stamceller med udtryk konstruktioner for fluorescerende organelle markører. Således kan cellulære morfologier og subcellulært strukturer analyseres med høj rumlige og tidsmæssige opløsning i forskellige celletyper, som bevarer deres vigtigste funktioner.

culture and transfection of zebrafish primary cells

Zebrafisk embryoner er gennemsigtige og udvikle hurtigt uden for mor, således giver mulighed for fremragende i vivo billeddannelse af dynamiske biologiske processer i en intakt og udvikle hvirveldyr. Men den detaljerede billeddannelse af morfologier af forskellige celletyper og subcellulært strukturer er begrænset i hele mounts. Derfor, vi etableret en effektiv og nem at bruge protokollen til kultur levende primærelementer fra zebrafisk embryoner og voksent væv.
Kort sagt, er 2 dpf zebrafisk embryoner dechorionated, deyolked, steriliseret, og dissocieres til enkelt celler med collagenase. Efter en filtrering skridt, primærelementer belagt på bunden glasfade og dyrkes i flere dage. Frisk kulturer, så meget som lang sigt differenciated dem, kan bruges til høj opløsning Konfokal billeddiagnostiske undersøgelser. Kulturen indeholder forskellige celletyper, med tværstribede myocytes og neuroner er fremtrædende på poly-L-lysin belægning. Specifikt etiket subcellulært strukturer af fluorescerende markør proteiner etableret vi også en elektroporation protokol, som giver Transfektion af plasmid DNA i forskellige celletyper, herunder neuroner. Således, i overværelse af operatøren definerede stimuli, komplekse celle adfærd og intracellulære dynamikken i primære zebrafisk celler kan vurderes med høj rumlige og tidsmæssige opløsning. Derudover ved hjælp af adult zebrafisk hjerne, vise vi, at den beskrevne dissociation teknik, samt de dyrkningsbaserede rammebetingelser, også arbejde for voksen zebrafisk væv.

Figur 1 g viser en overførte lys billede af en typisk kultur fra vildtype embryoner med tværstribede myocytes og klynger af neuron-lignende celler bliver mest rigelige. For at identificere bestemte celletyper mere let, en transgene linje med celle type-specifikke udtryk for en fluorescerende proteiner kan være brugt (figur 1 H).
