1. A method for generating a human pluripotent stem cell, comprising the steps of:
- (i) introducing one or more retroviral vectors comprising a gene encoding Oct3/4, a gene encoding Sox2 and a gene encoding Klf4 into an isolated human post-natal cell; and
(ii) culturing the cell of step (i) in the presence of an inhibitor of Rho kinase and/or a histone deacetylase inhibitor under conditions that maintain pluripotency and self-renewal, thereby generating a human pluripotent stem cell.

Abstract
Establishment of human pluripotent stem cells having properties close to human ES cells with the genome of the patient per se that can circumvent immunological rejection of transplanted cells from cells derived from a postnatal human tissue are described. Human pluripotent stem cells can be induced by introducing three genes of Oct3/4, Sox2 and Klf 4, or three genes of Oct3/4, Sox2 and Klf 4 plus the c-Myc gene or a histone deacetylase (HDAC) inhibitor of undifferentiated stem cells present in various human postnatal tissues in which each gene of Tert, Nanog, Oct3/4 and Sox2 has not undergone epigenetic inactivation.
