Kultivert primære HKCs har blitt mye utnyttet for å behandle sår i klinikker i mer enn tre tiår, og siden den gangen, det er alltid viktig å effektivt få tilstrekkelig antall celler for klinisk bruk i tide. Derfor, i praksis metoden konvensjonelle isolasjon som krever separasjon av overhuden fra huden, gjør det vanskelig å møte disse kravene, på grunn av lav avkastningen av celler og lav evnen å passasje voksen celler. Her beskriver vi en ny enkel metode vi utviklet å effektivt hente HKCs fra voksen vev baser...

Målet var å utvikle en enkel og effektiv protokoll for å isolere primære menneskelige keratinocytter (HKCs) fra voksen vev, spesielt for klinisk bruk. Huden epidermal stamceller, lokalisert i basale laget av huden, har et stort potensial til å spre og differensiere og gi keratinocytter for å beholde funksjonene av huden1,2,3, 4. HKCs isolert fra huden vev brukes for huden vev engineering og gjenfødelse, spesielt i reparasjon av skadet hud og i genterapi for klinisk bruk5,6. Hovedspørsmålet for HKC-baserte programmer er effektivt isolere og utvide stort antall HKCs med høyt potensial i vitro7,8. Selv om forskjellige forskningsgrupper har utviklet metoder for å produsere kulturer av stilk-lignende HKCs, er disse metodene ofte tidkrevende og komplisert å utføre og har andre begrensninger, som lav celle avkastning og å være begrenset av huden prøven brukt9. For eksempel innebærer den tradisjonelle metoden å isolere HKCs fra hudvevet en Totrinns enzymatisk fordøyelsen med en separasjon av overhuden dermis6. Denne metoden fungerer vanligvis bra for neonatal vev, men det blir svært vanskelig når isolere celler fra voksen vev.
Y-27632, en inhibitor av Rho-assosiert protein kinase (ROCK), har blitt rapportert å betydelig forbedre effektiviteten av epidermal stamcelleforskningen isolasjon og kolonien vekst10,11,12. I en tidligere studie oppdaget vi at Y-27632 forenkler klonal veksten av epidermal celler, men reduserer avkastningen av dermal celler med ulikt kontrollere uttrykket av vedheft molekyler13. Vi har også etablert et nytt betinget inoculation medium, kalt G-medium, som støtter vekst og avkastning på primære epidermal celler. Ved å kombinere G-medium med Y-27632, kan denne romanen metoden spontant skille epidermal og dermal celler etter enzym fordøyelsen, dermed fjerne trinnet overhuden-dermis separasjon13,14. Basert på tidligere rapporter, beskrive vi nå den detaljert prosedyren av denne nye metoden å isolere HKCs fra voksen hud vev.

a simplified and efficient method to isolate primary human keratinocytes from adult skin tissue

Primære menneskelige keratinocytter isolert fra frisk hud vev og deres ekspansjon i vitro har vært mye brukt for laboratorieundersøkelser og kliniske applikasjoner. Metoden konvensjonelle isolasjon av menneskelig keratinocytter innebærer en to-trinns sekvensiell enzymatisk fordøyelsen prosedyren, som har vist seg for å være ineffektive generere primære celler fra voksen vev lav celle utvinningsgrad og redusert celle levedyktighet. Vi har nylig rapportert en avansert metode å isolere menneskelige primære epidermal progenitor celler fra huden vev som benytter den Rho kinase inhibitor Y-27632 i medium. Sammenlignet med tradisjonelle protokollen, denne nye metoden er enklere, enklere og mindre tidkrevende, og øker epithelial stamcelleforskningen avkastning og forbedrer karakteristikkene stilk cellen. Videre den nye metodikken krever ikke separasjon av overhuden fra huden, og er derfor egnet for isolere celler fra ulike typer voksen vev. Denne nye isolasjon metoden overvinner de store manglene av konvensjonelle metoder og er mer egnet for å produsere store mengder epidermal celler med høy styrke både for laboratorier og kliniske applikasjoner. Her beskriver vi den nye metoden i detalj.

Skjematisk diagrammer av den nye metoden (figur 1A) og det tradisjonelle metoden (figur 1B) presenteres i figur 1. Det tradisjonelle metoden er en totrinns fordøyelsen, som krever en 2-dagers prosedyre. Den nye metoden er derimot en ettrinns fordøyelsen, som tar rundt 3 timer utføre. Viktigere, kan ettrinns nye metoden få to bestander (epidermal og dermal celler) samtidig, som avhenger av tilsted...
