Disse teknikker blev udviklet med støtte fra LabEx primtal (ANR-11-LABX-0063), Contrat Plan-Etat-regionen (CPER) inden for de videnskabelige rammer ETOILE (CPER 2009-2013) og Lyric Grant Inka-DGOS-4664.

Bemærk: Boyden kammer og bunden assays uden inddragelse af ECM omtales som migration assay, og de samme assays med ECM er benævnt invasion assay.
1. Boyden kammer Assay
Bemærk: Denne protokol er tilpasset til linjen SQ20B celle, som er afledt af en tilbagevendende hoved og hals planocellulært karcinom (HNSCC) larynx cancer og var fremstillet af John Little (Boston, MA, USA).

Vi rapporterer her to forskellige metoder til at studere cellen invasion og migration processen. Analysen af denne proces er vigtigt at forstå de faktorer, der er involveret i metastatisk gentagelse, som kunne forklares med øgede motilitet af en delpopulation af kræftceller kaldes kræft stamceller10,11.
Boyden kammer eksperiment er en de hyppigst anvendte teknikker til at udforske celle invasion og migration. En fordel ved denne ti...

Celle invasion og migration er involveret i udbredelsen af kræftceller, som er hovedårsagen til modstanden mod behandling1 og kan føre til locoregionale eller metastatisk fornyet efter kræft behandling2. Epitel-mesenchymale overgangen (EMT) er den indledende proces af celle invasion-migration i hvilke kræft celler skifte fra en epitelial til en mesenchymale fænotype. E-Cadherin er en ekstracellulære markør af epitel fænotype3, og øget udtryk for N-cadherin og vimentin er karakteristisk for mesenchymale fænotype4. Indvandring afhænger også kræftceller iboende evne til at invadere den ekstracellulære matrix (ECM) gennem handling af matrix metalloproteases5.
Denne invasion-migration mekanisme er blevet beskrevet for kræft på mange steder, især i hoved og hals kræft6. Mange forskere har fokuseret på migration og invasion processerne for bedre at forstå hvordan kræftceller formidle i håb om, at denne viden vil føre til ny behandling strategier. Det er afgørende, at disse undersøgelser udføres ved hjælp af pålidelig og reproducerbar assays.
In vitro analyse af celle motilitet kan være udfordrende. Udviklet for mange år siden, anses Boyden kammer analysen for at være standard for invasion-migration analyse7. Men det er tidskrævende og er ofte unøjagtige. En anden test er den sårheling assay8, som indebærer at gøre en skramme på en celle éncellelag kultur og fanger billeder af celle invasion og migration med faste tidsintervaller. Denne teknik er blevet kritiseret vidt på grund af de store variationer mellem resultaterne af to successive tests. Dog har anvendelsen af moderne teknologier, især i mikroskopi, bedre reproducerbarhed af scratch sår assay. Video mikroskoper nemt kan indføres i væksthuse og kan generere real-time billeder af celle migration. Disse enheder optage mikroskopiske data og automatisk analyse af sår celle sammenløbet med tiden. Formålet med dette papir er at beskrive Boyden kammer assay og optimeret scratch sår analysen og diskutere fordele og svagheder ved hver metode.

evaluation of the cell invasion and migration process: a comparison of the video microscope-based scratch wound assay and the boyden chamber assay

Tumorcellerne invasion og migration evner er vigtigste bidragydere til kræft progression og gentagelse. Mange undersøgelser har udforsket migration og invasion evne at forstå, hvordan kræftceller udbrede, med formålet at udvikle nye behandling strategier. Analyse af cellulære og molekylære grundlag for disse evner har ført til karakterisering af celle mobilitet og de fysisk-kemiske egenskaber af cytoskelettet og cellulære mikromiljø. I mange år, har Boyden kammer assay og scratch sår analysen været standardteknikker at studere cellen invasion og migration. Disse to teknikker har imidlertid begrænsninger. Boyden kammer assay er vanskelig og tidskrævende, og scratch sår analysen har lav reproducerbarhed. Udviklingen af moderne teknologier, især i mikroskopi, har øget reproducerbarhed af scratch sår assay. Ved hjælp af kraftfulde analyse systemer, kan et "i-inkubator" video mikroskop bruges til at levere automatisk og real-time analyse af celle migration og invasion. Formålet med dette papir er at rapportere og sammenligne de to assays bruges til at studere cellen invasion og migration: Boyden kammer assay og en optimeret in vitro- video mikroskop-baseret skrabelod sår assay.

Vi rapporterer her to forskellige metoder til at analysere celle invasion og migration. Figur 1 viser Boyden kammer eksperiment. Indsætter er placeret i en følgesvend plade med chemoattractant medium, og cellerne udsås i CM. Membranen kan være ubestrøget (migration assay) eller overtrukket (invasion assay). Cellerne udsås i det øverste kammer i s-CM. Den nedre kammer er fyldt med CM som en chemoattractant. Cellerne er fast før den fordobling tid.
