Mange forsøg på at generere humane IPSC&#39;er med ikke-integrerende eller ikke-genetiske fremgangsmåder til at generere klinisk sikre IPSC&#39;er. Hidtil har disse metoder udviser ekstremt lave effektivitet og kræver yderligere optimering for at forbedre reproducerbarheden 11-14.

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

Humane embryonale stamceller (hESCs) er pluripotente og en uvurderlig cellulære kilder til in vitro sygdom modellering og regenerativ medicin 1. Det er tidligere blevet vist, at humane somatiske celler kan omprogrammeres til pluripotens ved ektopisk ekspression af fire transkriptionsfaktorer (Oct4, Sox2, Klf4 og Myc) og blive induceret pluripotente stamceller (IPSC&#39;er) 2-4. Ligesom hESCs, er menneskelige IPSC&#39;er pluripotente og en potentiel kilde til autologe celler. Her beskriver vi den protokol, at omprogrammere humane fibroblastceller med de fire omprogrammeringsbeslutninger faktorer klonet i GFP-holdige retroviral rygraden 4. Brug følgende protokol, vi skaber menneskelige IPSC&#39;er i 3-4 uger under menneskelige ESC kultur tilstand. Humane IPSC kolonier ligner hESCs i morfologi og viser tab af GFP-fluorescens som følge af retroviral transgen lyddæmpning. IPSC kolonier isoleres mekanisk under en fluorescens microscoPE opføre sig på samme måde som hESCs. I disse celler, detektere vi ekspressionen af ​​multiple pluripotens gener og overflademarkører.
