Abstract
Provided are a method for preparing an induced pluripotent stem cell and a composition used in the method. The method comprises: introducing a composition for promoting the formation of an induced pluripotent stem cell into a somatic cell, the composition comprising: (i) a c-Jun antagonist and one group of factors from among the following seven such groups: (1) Sox2, Klf4 and c-Myc, (2) Klf4 and c-Myc, (3) Oct3/4, Klf4 and c-Myc, (4) Sox2, Nanog and Lin28, (5) Oct3/4, Nanog and Lin28, (6) Oct3/4, Klf and Sox2, and (7) Klf4 and Sox2; or (ii) the c-Jun antagonist, Jhdm1b and Id1, and at least one of Glis1, Sall4 or Lrh1; or (iii) the c-Jun antagonist, Jhdm1b and Id1, and at least one of: Oct4, Klf4, Sox2, Lin28, Esrrb, Lef1, Utf1 or miRNA C. The present method allows for successful preparation of induced pluripotent stem cells with no generation of abnormal chromosomes.
