Induced pluripotent stem cell (iPSC) with the pluripotency of an embryonic stem cell. These genes were 

a. Sox2 and Oct4 (Oct3, Oct3/4, and Pou5f1) -which activated Nanog and other transcription factors that   established pluripotency and blocked differentiation

b. c-Myc which opened up chromatin and made the genes accessible to Sox2, Oct4, and Nanog

c. Klf4 -which prevents cell death
