Pramef12 enhances reprogramming into naive iPS cells.

ABSTRACT: Somatic cells can be reprogrammed into induced pluripotent stem (iPS) cells by forced expression of the transcription factors Oct3/4, Klf4, Sox2, and c-Myc (OKSM). Somatic cell nuclear transfer can also be utilized to reprogram somatic cells into totipotent embryos, suggesting that factors present in oocytes potentially enhance the efficiency of iPS cell generation. Here, we showed that preferentially expressed antigen of melanoma family member 12 (Pramef12), which is highly expressed in oocytes, enhances the generation of iPS cells from mouse fibroblasts. Overexpression of Pramef12 during the early phase of OKSM-induced reprogramming enhanced the efficiency of iPS cell derivation. In addition, overexpression of Pramef12 also enhanced expression of naïve pluripotency-associated genes, Gtl2
