Den nuværende manuskript beskriver en lys plade eller enkelt plan belysning mikroskopi (SPIM) anordning, som er optimeret til 3-dimensionelle celle systemer, fx flercellede tumor sphæroider (MCT). Tre eksempler på applikationer omfatter (1) optagelse af et cytostatisk lægemiddel og dets delvis konvertering til et nedbrydningsprodukt (hvis bidrag til kemoterapeutisk effekt mangler stadig at blive evalueret), (2) målinger af redox stat, ved hjælp af en genetisk kodet glutathion-sensor på tilsætning af et ...

Ud over at veletablerede metoder (konfokal eller multi-foton laser scanning mikroskopi 1-4, struktureret belysning mikroskopi 5,6) lys ark eller enkelt plan belysning mikroskopi (SPIM) har vist sig at være en værdifuld metode til 3D billedbehandling 7,8, 9. Af særlig interesse er anvendelsen til 3-dimensionelle cellekulturer, f.eks flercellede tumor sfæroider (MCT), der anvendes i stigende grad til lægemiddelforskning forskning 10,11. Desuden SPIM er en privilegeret metode, når selv efter langvarig eksponering eller gentagne målinger lave doser lys er forpligtet til at opretholde prøven levedygtighed, da der for måling af hvert plan af prøven kun dette plan udsættes for lys. Dette er i modsætning til andre mikroskopi teknikker, hvor til påvisning af hver brændplanet hele prøven er belyst, således at der ved registrering af adskillige planer lysdosis opsummerer og kan skade prøven 12. </p&gt; Lys ark mikroskopi eller SPIM er baseret på belysning af prøven i retning vinkelret på observation vej, enten ved brug af en cylindrisk linse eller ved at scanne spændende laserstråle (for en gennemgang se ref. 8). Dette kræver ofte særlige prøvekamre 13,14 eller matricer, fx agarose 7,15, implementeret i særlige høje omkostninger mikroskoper. Som et alternativ til disse systemer et sammenligneligt enkelt belysningsindretning til SPIM er blevet udviklet og tilpasset til en konventionel inverteret mikroskop 16 (se figur 1). Den består af en laserstråle udvidet til en diameter på 8 mm og fokuseret af en cylindrisk linse (brændvidde 50 mm, numerisk åbning: 0,08) til en lys ark på 6-10 um tykkelse over en dybdeskarphed på omkring 100 um . Prøver er placeret i et rektangulært kapillær 600-900 um indvendig diameter placeret foran mikroskopet mål lens for fluorescensdetektion. Disse hovedtræk er i øjeblikket udfyldt og optimeres ved brug af avancerede mikro-kapillære tilgange til at holde og til at rotere prøverne, den synkrone justering af den lysende lys ark (i aksial retning) og objektiv, der anvendes til fluorescens detektion (identisk optisk vej længder af forskydning kræver en korrektion af det mekaniske foder), og tilpasning af et mikrofluidisk system til anvendelse af fluorescerende farvestoffer, farmaceutiske midler eller lægemidler, og dermed minimere de krævede mængder og udgifter.

single plane illumination module and micro-capillary approach for a wide-field microscope

Et modul til lyspladen eller enkelt plan belysning mikroskopi (SPIM) er beskrevet som let tilpasses til en omvendt bredt synsfelt mikroskop og optimeret til 3-dimensionelle cellekulturer, f.eks flercellede tumor sfæroider (MCT). De SPIM excitation modul former og afbøjer lyset sådan at prøven belyses af en lys plade vinkelret på påvisning af mikroskopet. Systemet er kendetegnet ved anvendelse af en rektangulær kapillær til at holde (og i en avanceret udgave også af en mikro-kapillær fremgangsmåde for roterende) prøverne ved synkron justering af belysningen plader og objektivlinsen anvendes til fluorescens detektion samt ved tilpasning af en mikrofluid system til anvendelse af fluorescerende farvestoffer, farmaceutiske midler eller lægemidler i små mængder. En protokol til at arbejde med dette system er givet, og nogle tekniske detaljer er rapporteret. Repræsentative resultater omfatter (1) måling af optage et cytostatisk lægemiddel (doxorubicin) og en delvis omdannelse til et nedbrydningsprodukt, (2) redox målinger ved anvendelse af en genetisk kodet glutathion sensoren ved tilsætning af et oxidationsmiddel, og (3) initiering og mærkning af cellenekrose ved inhibering af mitokondrie respiratoriske kæde. Forskelle og fordele ved den foreliggende SPIM modul i sammenligning med de eksisterende systemer er diskuteret.

Eksperiment 1: Cell sphæroider inkuberet med et kemoterapeutisk lægemiddel En z-stak scanning af en tidligere inkuberet MCF-7-celle sfæroide (8 uM doxorubicin, 6 timer) er afbildet i figur 3.
