Uttrykk av fire transkripsjonsfaktorer omprogrammerer menneskelige fibroblaster til iPSCs. Mange forsøk ble gjort for å generere menneskelige iPSCs med ikke-integrere eller ikke-genetiske tilnærminger for å generere klinisk trygge iPSCs. Så langt disse metodene viser svært lav virkningsgrad og krever ytterligere optimalisering for å forbedre reproduserbarhet 11-14. Retro-eller lentiviral metoder lett brukes til å utlede og anvende iPSCs for human in vitro sykdom modeller, som er mindre avheng...

reprogramming human somatic cells into induced pluripotent stem cells (ipscs) using retroviral vector with gfp

Humane embryonale stamceller (hESCs) er pluripotent og en uvurderlig mobilnettet kilder for in vitro sykdom modellering og regenerativ medisin en. Det er tidligere vist at humane somatiske celler kan omprogrammeres til pluripotency ved ektopisk uttrykk av fire transkripsjonsfaktorer (Oct4, Sox2, Klf4 og myc) og bli indusert pluripotent stamceller (iPSCs) 2-4. Som hESCs, menneskelige iPSCs er pluripotent og en potensiell kilde for autologe celler. Her beskriver vi protokollen for å omprogrammere menneskelige fibroblast celler med de fire omprogrammering faktorene klonede inn GFP-inneholder retrovirale ryggrad 4. Bruk følgende protokoll, genererer vi menneskelige iPSCs i 3-4 uker etter menneskelig ESC kultur tilstand. Menneskelige iPSC kolonier likne hESCs i morfologi og vise tap av GFP fluorescens som følge av retrovirale transgenet stanse. iPSC kolonier isolert mekanisk under en fluorescens microscope oppføre seg i en lignende måte som hESCs. I disse cellene, oppdager vi uttrykket av flere pluripotency gener og overflate markører.
