Kulturperler primære HKCs har været bredt udnyttet til at behandle sår i klinikker i mere end tre årtier, og siden tid, det har altid været vigtigt at effektivt opnå tilstrækkeligt antal celler til kliniske applikationer i tide. Metoden konventionelle isolation, der kræver adskillelse af epidermis til dermis, gør det derfor vanskeligt at opfylde disse krav, på grund af det lave udbytte af celler og den lave evne til passage voksne celler i praksis. Her, beskriver vi en ny enkel metode vi udviklede for at opnå ...

Målet var at udvikle en enkel og effektiv protokol for at isolere primære humane keratinocytter (HKCs) fra voksne væv, især til kliniske applikationer. Huden epidermal stamceller, lokaliseret i den basale lag af huden, besidder et stort potentiale til at formere sig og differentiere og give keratinocytter for at opretholde funktionerne af huden1,2,3, 4. HKCs isoleret fra hud væv er almindeligt brugt til hud væv manipulation og regenerering formål, især i reparation af beskadiget hud og genterapi for kliniske applikationer5,6. Det centrale spørgsmål for HKC-baserede programmer er effektivt isolerer og udvide stort antal HKCs med høj potentiel in vitro-7,8. Selv om forskellige forskergrupper har udviklet metoder til at producere kulturer af stilk-lignende HKCs, er disse metoder undertiden tidskrævende og kompliceret at udføre og har andre begrænsninger, såsom lav celle udbytter og er begrænset af typen af huden modellen brugte9. For eksempel, indebærer den traditionelle metode til at isolere HKCs fra hud væv en to-trins Enzymatisk nedbrydning med en adskillelse af epidermis fra dermis6. Denne metode fungerer normalt godt for neonatal væv, men det bliver meget vanskeligt, når det bruges til at isolere celler fra voksne væv.
Y-27632, en hæmmer af Rho-forbundet protein kinase (ROCK), er blevet rapporteret til betydeligt øge effektiviteten af epidermale stamceller isoleret og koloni vækst10,11,12. I en tidligere undersøgelse opdagede vi at Y-27632 letter den klonede vækst af epidermale celler, men reducerer udbyttet af dermal celler af varierende kontrollerende udtryk for vedhæftning molekyler13. Vi har også etableret et nyt konditioneret podning medie, kaldet G-medium, som støtter vækst og udbytte af primære epidermale celler. Ved at kombinere G-medium med Y-27632, kan denne nye metode spontant adskille dermal og epidermal celler efter enzym fordøjelse, dermed fjerne trin i epidermis-dermis adskillelse13,14. Baseret på tidligere betænkninger, beskrive vi nu den detaljerede procedure af denne nye metode til at isolere HKCs fra voksen hudvæv.

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

Primære humane keratinocytter isoleret fra frisk hud væv og deres ekspansion i vitro har været udbredt, laboratorie-forskning og kliniske applikationer. Metoden konventionelle isolation af humane keratinocytter indebærer en totrinsprocedure for sekventielle Enzymatisk nedbrydning, som har vist sig for at være ineffektive i generere primærelementer fra voksent væv på grund af lav celle genfindingsprocenten og reduceret celle levedygtighed. Vi har for nylig rapporteret en avanceret metode til at isolere menneskelige primære epidermal stamceller fra væv, hud, der udnytter Rho kinase inhibitor Y-27632 på mellemlang. Sammenlignet med den traditionelle protokol, denne nye metode er enklere, lettere og mindre tidskrævende, og øger epitelial stamcelle udbytte og forbedrer deres stamcelle karakteristika. Desuden, den nye metode kræver ikke adskillelse af epidermis til dermis, og, derfor, er velegnet til isolering af celler fra forskellige typer af voksen væv. Denne nye isolation metode overvinder de store mangler ved konventionelle metoder og er mere egnet til at producere store mængder af epidermale celler med høj potens både laboratorium og kliniske applikationer. Her beskriver vi den nye metode i detaljer.

Skematiske diagrammer af den nye metode (figur 1A) og den konventionelle metode (figur 1B) er præsenteret i figur 1. Den konventionelle metode er en to-trins fordøjelse, som kræver en 2-dages procedure. Den nye metode er derimod en et-trins fordøjelsen, hvilket tager omkring 3 timer for at udføre. Vigtigere, kan et-trins nye metode få to populationer (epidermale og dermal celler) på samme tid,...
