Baseret på den omfattende litteratur, der er blevet etableret for analyse af sidelinje (LL) regenerering i embryonale og larve zebrafisk 8,24,25, målet for vores undersøgelse var at udvikle en kvantitativ analyse for sidelinje regenerering i zebrafisk, der kunne anvendes på sygdomsmodeller, der er bedst undersøgt i den voksne fisk. Vi fandt, at visse kritiske punkter er vigtige, når anvendelse af procedurer, der er udviklet til embryonale / fiskelarver til voksne fisk. Den vigtigste af disse punkter bet...

Den laterale linie (LL) system er en mechanosensory orgel findes i både fisk og padder, der er ansvarlig for hørelse, balance, rheotaxis og medierende adfærd, såsom skolegang og rovdyr undgåelse 1-5. Det består af klynger af hårceller omgivet af støtte celler, som begge er placeret i strukturer, der kaldes neuromasts 6. Disse neuromasts er typisk organiseret i lodrette linier (kaldet masker) langs længdeaksen af ​​kroppen og halen med nogle vandrette sting observeret i hovedet af fisken. I den voksne, neuromasts er betydeligt større i antal inden for de masker, som i forhold til embryonale eller fiskelarver 6. Biomedicinske studier i zebrafisk har fokuseret på effekten af antibiotisk behandling, støj-induceret traumer, kronisk infektion osv. på hårceller 7,8 i et forsøg på bedre at forstå deres effekter i mennesker. I modsætning til de fleste hvirveldyr, teleosts såsom zebrafisk (Danio rerio), har evnen til at regenerere tabte hårceller. Zebrafisk er særligt nyttige på grund af deres hurtige udviklingstid og høj regenerationsevne. Til dato, men; zebrafisk undersøgelser af lateral udvikling og / eller regenerering linje har primært udnyttet den embryonale og larvestadiet fisk på grund af det reducerede antal sidelinje neuromasts der giver mulighed for lettere optælling og analyse 6,9,10. Men som mange zebrafisk modeller af neurologiske og ikke-neurologiske sygdomme 11-16 undersøgt i den voksne fisk og ikke larverne, vi fokuseret på at udvikle en sidelinje regenerativ assay i voksen zebrafisk hjælp gentamicin (et aminoglykosid tidligere anvendt i zebrafisk larver og mere for nylig brugt med voksne fisk 17), således at en analyse var til rådighed, der kunne anvendes på nuværende voksne zebrafisk sygdomsmodeller. Mens tidligere offentliggjorte procedurer Van Trump et al. 17 fastsat betingelserne for hår celle ablation i den voksne fisk, de ikke etablere en standard kurve for neuromast regeneration, som er nødvendig for kvantitativ sammenligning mellem kontrol og eksperimentelle grupper såsom ved brug af transgene zebrafisk linjer eller farmakologisk inducerede sygdomstilstande i zebrafisk 18. Vi fulgte derfor procedurerne i Van Trump et al. 17 til hår celle ablation, men bygget på deres arbejde med at etablere en standard kurve neuromast regenerering at gøre det muligt for efterforskerne at bruge vores data, når man sammenligner kontrol og eksperimentelle grupper som med voksne zebrafisk sygdomsmodeller . Assayet blev også designet til at tillade forlængelse af analysen til de enkelte hår celle, når en højere grad af opløsning er påkrævet.

an assay for lateral line regeneration in adult zebrafish

På grund af den kliniske betydning af hørelse og balance lidelser hos mennesker, har modelorganismer såsom zebrafisk er blevet brugt til at studere lateral udvikling og regeneration linje. Zebrafisken er særligt attraktivt for sådanne undersøgelser på grund af sin hurtige tid udvikling og dens høje regenerationsevne. Til dato har zebrafisk studier af sidelinje regenerering anvendes hovedsageligt fisk af embryonale og larvestadier på grund af det lavere antal neuromasts på disse stadier. Dette har gjort kvantitativ analyse af sidelinje regenerering / og eller udvikling lettere i de tidligere udviklingsstadier. Fordi mange zebrafisk modeller af neurologiske og ikke-neurologiske sygdomme studeres i den voksne fisk og ikke i embryoet / larver, vi fokuseret på at udvikle en kvantitativ sidelinje regenerativ assay i voksen zebrafisk, således at en analyse var til rådighed, der kunne anvendes til løbende voksne zebrafisk sygdomsmodeller. Med udgangspunkt i tidligere undersøgelser af Van Trump m.fl. 17. der er beskrevet procedurer for ablation af hårceller i voksen mexicanske blind hule fisk og zebrafisk (Danio rerio), var vores analyse designet til at tillade kvantitativ sammenligning mellem kontrol og eksperimentelle grupper. Dette blev opnået ved at udvikle en regenerativ neuromast standardkurve baseret på procenten af ​​neuromast genkomst over en 24 timers periode efter gentamicin-induceret nekrose af hårceller i et defineret område af den laterale linie. Assayet blev også designet til at tillade forlængelse af analysen til de enkelte hår celle niveau, når en højere grad af opløsning er påkrævet.

Optimering af procedurerne for kvantificering neuromast regenerering af sidelinjen i voksen zebrafisk. De neuromasts af larve zebrafisk er let kvantificerbare; Men den laterale linie af den voksne zebrafisk har et langt større antal neuromasts pr sting gør kvantitative analyser sværere 6,17,19,20. Som det ses i figur 1A, lederen har et betydeligt højere antal neuromasts forhold til enten midtersektionen eller hale; med halen region, der har de...

An Assay for Lateral Line Regeneration in Adult Zebrafish

Fordi mange zebrafisk modeller af neurologiske og ikke-neurologiske sygdomme er undersøgt i voksne fisk snarere end embryo / larver, har vi udviklet en kvantitativ sidelinje regenerativ assay, der kan anvendes til voksne zebrafisk sygdomsmodeller. Analysen involverede opløsning på 1) neuromast og 2) individuelle hår celle niveauer.
