I denne artikel beskrives en reproducerbar protokol til isolationen og kulturen af ​​hjertemyocytter, endotelceller og fibroblaster. Denne protokol beskriver den samtidige og højkvalitets isolering af de vigtigste celletyper af hjertevæv, dvs. cardiomyocytter, endotelceller og fibroblaster i modsætning til blot en celletype. Et kritisk trin i isoleringsproceduren er den korrekte fordøjelse af hjertevævet. Hvis fordøjelsen er ufuldstændig, kan der stadig opnås et stort antal myocytter, men deres kval...

Rodent modeller er længe blevet brugt som redskaber til at udvide vores forståelse af kardiovaskulær fysiologi i sundhed og sygdom. 1 Selvom disse dyremodeller giver os mulighed for at forstå patofysiologien af ​​en sygdom på orgenniveau og at analysere farmakokinetikken og farmakodynamikken af ​​forskellige farmakologiske midler anvendt til behandling af hjerte-kar-sygdomme, forståelse af de molekylære mekanismer for udvikling af hjerte-kar-sygdomme og bidrag fra en bestemt Celle type kræver brug af in vitro cellekultur modeller. Til dette formål er der udviklet forskellige immortaliserede cellelinier fra det kardiovaskulære system; 2 , 3 er frisk isolerede primære celler imidlertid fysiologisk og funktionelt mere relevante for levende væv og organismer. Hjertet er et alsidigt organ, der indeholder alle hovedtyper af celler i kardiovaskulære sYstem, og rottehjerte er stadig en almindeligt anvendt model til forståelse af kardiovaskulær fysiologi. I de sidste par årtier er forskellige metoder til isolering af individuelle celletyper fra hjertevæv blevet beskrevet; 4 , 5 , 6 , 7, men disse metoder fokuserer kun på isolering af en specifik celletype, hvilket resulterer i tab af andre typer celler, der ikke længere kan anvendes til cellulær analyse. Her beskrives en optimeret protokol, som muliggør samtidig og højkvalitets isolering af de vigtigste celletyper af hjertevæv, dvs. cardiomyocytter, endotelceller og fibroblaster. Alle disse celletyper kan anvendes i forskellige eksperimentelle opsætninger 8 , 9 , 10 og til analyse af cellecelleinteraktioner fra det samme dyr.

simultaneous isolation of high quality cardiomyocytes, endothelial cells, and fibroblasts from an adult rat heart

Rotten er en vigtig dyremodel, der anvendes i kardiovaskulær forskning, og rotte-hjerteceller anvendes rutinemæssigt til in vitro- analyse af de molekylære mekanismer for kardiovaskulær sygdomsprogression, såsom hjertehypertrofi, fibrose og aterosklerose. Selv om adskillige forsøg med variabel succes er blevet gjort for at udvikle immortaliserede cellelinier fra kardiovaskulærsystemet for at forstå disse cellulære mekanismer, tilbyder primære celler et mere naturligt og tæt på in vivo- miljø til sådanne undersøgelser. Derfor har forskellige laboratorier, der arbejder på en bestemt celletype, udviklet protokoller til isolering af individuelle typer af hjerteceller af rotteceller af interesse. En protokol, der tillader isolering af mere end en celletype, mangler imidlertid. Her beskrives en optimeret protokol, der muliggør isolering af store hjertecelletyper af høj kvalitet (cardiomyocytter, endotelceller og fibroblaster) fra et enkelt præparat og muliggørR bruges til cellulære analyser. Dette tillader den mest effektive udnyttelse af tilgængelige ressourcer, hvilket kan spare tid og reducere forskningsomkostningerne.
