Vi vil gerne takke Dr. Lee Niswander og Dr. Rada Massarwa for deres tekniske ekspertise og bidrag til den skivekultur-konfokale billedprotokol, der beskrives her. Yderligere tak til Dr. Kalen Dionne, der gav ekspertise vedrørende optimering af hjernevaskesplitning og kulturparametre.

Inden indsamling af patientvævsprøver indledes, skal informeret samtykke indhentes fra hver patient under en godkendt Institutional Review Board (IRB) protokol. Forfatterne af denne protokol modtog samtykke til det arbejde, der er beskrevet under godkendte IRB-protokoller ved University of Colorado Hospital og Inova Fairfax Hospital. Data indsamlet fra disse skivekulturer blev ikke brugt til at styre patientbehandlingsbeslutninger. 1. Forskæring Fremstilling <ol><li> Forbered &quot;tiss...

Organotypiske skivekulturer fra humant kræftvæv giver en attraktiv og underudnyttet platform til præklinisk translationel eksperimentering. Forståelse af befolkningsniveauadfærd hos tumorceller med hensyn til migration, proliferation og celledød i det naturlige tumormikromiljø mangler. Kritisk kan undersøgelse af tumorrespons på terapi på en dynamisk, tidsopløst måde på celleadfærdens niveau afdække nye mekanismer for behandlingsresistens. Humane tumorskivekulturer tilvejebringer en forbindelse mellem den...

Laboratorieundersøgelsen af ​​glioblastom (GBM) hindres af mangel på modeller, som trofast rekapitulerer de krævede patologiske karakteristika ved den menneskelige sygdom, nemlig tumorcellemigration og invasion. Sammenligningsundersøgelser af 2D- og 3D in vitro- invasionstest samt 3D-gnavere af slagtekulturer har afdækket mekanisk forskelligartede cellulære migrationsprogrammer i disse to sammenhænge, ​​der potentielt begrænser translatabiliteten af ​​fund fra 2D-systemer til den humane sygdom 1 , 2 , 3 . Det organotype tumorskivekultur- og billeddannelsesparadigm, der beskrives her, tillader undersøgelse af tumorcellemigration inden for skiver af humant tumorvæv ex vivo opnået fra kirurgisk resektion. Således tilvejebringer skivekulturer af kirurgisk resekteret tumorvæv i forbindelse med time-lapse-konfokalmikroskopi en platform til at studere tumorcelle-migration i den nativeMikro-miljø uden vævsopløsning eller kulturpassage. Der er omfattende litteratur, der anvender gnavere hjerneskivekulturmodeller af GBM genereret fra humane tumor-xenotransplantater, retrovirale inducerede tumorer og cellulære overlejringer til undersøgelse af tumorinvasion 1 , 2 , 3 , 4 , 5 . For nylig har flere grupper beskrevet genereringen af ​​organotypiske skivekulturer direkte fra humant GBM væv 6 , 7 , 8 , 9 , 10 . Der er imidlertid markant variation blandt offentliggjorte protokoller med hensyn til udskæringsteknik og kulturmedier. Endvidere har anvendelsen af ​​organotypiske skivekulturer fokuseret på statiske eksperimentelle endepunkter, der har medtaget ændringer i celle signalerNg, proliferation og død. Protokollen beskrevet heri udvider på tidligere skivekulturparadigmer ved at inkorporere tidsopløst observation af dynamisk tumorcelleadfærd ved hjælp af time-lapse laser scanning-konfokal mikroskopi. Nylig opdagelse af inter 11 og intratumoral 12 , 13 genetisk variation i humant GBM understreger vigtigheden af ​​at forbinde denne heterogenitet med tumorcelleadfærd og dens implikationer på tumorrespons til terapi. Her rapporterer vi en strømlinet og reproducerbar protokol til brug af direkte skivekulturer fra et humant cancervæv til at visualisere tumorcelleindvandring i nær real-time.

a human glioblastoma organotypic slice culture model for study of tumor cell migration and patient-specific effects of anti-invasive drugs

Glioblastom (GBM) har fortsat en ekstremt dårlig klinisk prognose på trods af kirurgisk, kemoterapeutisk og strålebehandling. Progressiv tumorinvasion i omgivende hjerneparenchyma repræsenterer en varig terapeutisk udfordring. For at udvikle anti-migrationsterapier til GBM er det nødvendigt med modelsystemer, der giver en fysiologisk relevant baggrund for kontrolleret forsøg. Her præsenterer vi en protokol til generering af skivekulturer fra humant GBM væv opnået under kirurgisk resektion. Disse kulturer tillader ex vivo- eksperimentering uden passage gennem dyre-xenografter eller enkeltcellekulturer. Desuden beskriver vi brugen af ​​time-lapse laser scanning konfokal mikroskopi i forbindelse med cellesporing for kvantitativt at studere tumorcellernes tilknyttede adfærd og tilhørende respons på terapeutik. Skiverne produceres reproducerbart inden for 90 minutter af kirurgisk vævsopkøb. Retroviralt medieret fluorescerende celle laBeling, konfokal billeddannelse og tumorcelle migrationsanalyser udføres efterfølgende inden for to ugers kultur. Vi har med succes brugt disse skivekulturer til at afdække genetiske faktorer i forbindelse med øget migrerende adfærd i human GBM. Desuden har vi valideret modelens evne til at detektere patientspecifik variation som svar på anti-migrationsbehandling. Flytning fremad er humane GBM skivekulturer en attraktiv platform til hurtig ex vivo vurdering af tumorfølsomhed over for terapeutiske midler for at fremme personlig neuro-onkologisk terapi.

<html> Vores gruppe har med succes genereret skivekulturer fra over 50 patienter under igangværende GBM resektion. Denne skive generation, kultur, retroviral-mærkning, billeddannelses- og migrationsanalyseprotokol er blevet strømlinet i en reproducerbar arbejdsgang ( figur 1 ). Kritisk viser disse organotypiske GBM-skiver overensstemmelse med det oprindelige tumorvæv gennem hele kulturen, herunder vedligeholdelse af patologiske kendetegn og mikroglia op til 15 dage i ...
