Induced pluripotent stem (iPS) cells are generated from mouse and human somatic cells by the introduction of four genes, but with low efficiency. Here it is reported that 10% of transduced mouse embryonic fibroblasts lacking p53 became iPS cells, even without the Myc retrovirus, and iPS cells were also generated from terminally differentiated T lymphocytes in the p53-null background.
