Differentiated cells can be reprogrammed into induced pluripotent stem (iPS) cells through the transient overexpression of a small number of transcription factors. These iPS cells resemble embryonic stem (ES) cells but, until now, they had not passed the most stringent test of pluripotency by generating full-term or adult mice in tetraploid complementation assays. Here, fertile adult mice derived entirely from iPS cells are reported.
