For at demonstrere indsprøjtning af mikropartikler i zebrafisk nyre, brugte vi semipermeabel mikrokapsler indlæst med en indikator farvestof. Protokollen indeholder således instrukser for fabrikation af mikrokapsler ved hjælp af samlingen lag på lag af oppositely ladede polyelectrolytes7,8,15,16,17 ,18 (<strong class="x...

Administration af mikro-størrelse partikler i en animalske organisme er en vigtig opgave i områder som medicin og vaccine levering1, vaskulatur visualisering2, transgene celle implantation3og lille optisk sensor implantation 4 , 5. implantation procedure for individuel partikler i det vaskulære system af små laboratoriedyr er imidlertid vanskeligt, især for sarte organismer. Til populære forskning prøver som zebrafisk, anbefales det at disse procedurer afklares ved hjælp af video protokoller.
Intracardiac og kapillær microinjections kræver uddannet personale og unikke mikrokirurgi faciliteter for levering af microobjects i zebrafisk blod. Tidligere, en retro-orbital manuel injektion3 blev foreslået som en nem og effektiv metode til administration af hele celler. Imidlertid vores erfaring tager på grund af det lille område af øjet kapillære netværk, det meget praksis at opnå det ønskede resultat fra denne teknik.
Heri, beskrive vi en metode for robust og effektiv microparticle implantation i kredsløbet ved manuel indsprøjtning direkte ind i nyrevæv af voksen zebrafisk, som er rig på kapillærer og renal fartøjer. Denne teknik er baseret på video-protokollen til celle transplantation i zebrafisk nyre6, men de traumatiske og tidskrævende microsurgical skridt blev elimineret. Den foreslåede metode er kendetegnet ved lav dødelighed (0-20%) og høj effektivitet (70-90% succes), og det er let at bruge almindeligt udstyr.
En vigtig del af den foreslåede protokol er visualisering af den implanterede mikropartikler (hvis de er fluorescerende eller farvelagt) i gill kapillærer, som giver mulighed for kontrol af injektion kvalitet, en ru relativ vurdering af antallet af injiceres partikler, og påvisning af den spektrale signal for fysiologiske målinger direkte fra den cirkulerende blod. Som et eksempel på de mulige anvendelser af de beskrevne teknik, vi udviser i protokollen for i vivo målinger af zebrafisk blod pH ved hjælp af en microencapsulated fluorescerende sonde, SNARF-1, oprindeligt foreslået i Borvinskaya mfl. 20175.

simple and effective administration and visualization of microparticles in the circulatory system of small fishes using kidney injection

Systemisk administration af mikro-størrelse partikler ind i en levende organisme kan anvendes til Vaskulaturen visualisering, narkotika og vaccine levering, implantation af transgene celler og bittesmå optiske sensorer. Dog intravenøs microinjections i små dyr, der oftest anvendes i biologiske og veterinære laboratorier, er meget vanskelig og kræver uddannet personale. Heri, vise vi en robust og effektiv metode for indførelse af mikropartikler i kredsløbet af voksen zebrafisk (Danio rerio) ved indsprøjtning i fisk nyre. For at visualisere den indførte mikropartikler i Vaskulaturen, foreslår vi en simpel intravital imaging teknik i fisk gæller. In vivo overvågning af zebrafisk blod pH blev udført ved hjælp af en injiceres microencapsulated fluorescerende sonde, SNARF-1, til at vise en af de mulige anvendelser af de beskrevne teknik. Denne artikel giver en detaljeret beskrivelse af indkapsling af pH-følsom farvestof og viser principperne om hurtig injektion og visualisering af de opnåede mikrokapsler for in vivo optagelse af fluorescerende signal. Den foreslåede metode til injektion er kendetegnet ved en lav dødelighed (0-20%) og høj effektivitet (70-90% succes), og det er let at bruge almindeligt udstyr. Alle beskrevne procedurer kan udføres på andre små fiskearter såsom guppyer og medaka.

De opnåede resultater kommer fra en af de tre hovedkategorier af præsenteres protokollen: dannelsen af fluorescerende mikropartikler af indkapsling af et fluorescerende farvestof (figur 1), nyre injektion af mikrokapsler med yderligere visualisering i Gill kapillærer (figur 2 og 3) og endelig, i vivo spektrale optagelsen af SNARF-1 fluorescens at overvåge blod pH niveauer (<strong c...
