The embryonic stem cell line derivation from nonpermissive mouse strains is a challenging and highly inefficient process. The cellular reprogramming strategy provides an alternative route for generating pluripotent stem cell (PSC) lines from such strains. In this study, we successfully derived an enhanced green fluorescent protein (EGFP)-transgenic "N9" induced pluripotent stem cell (iPS cell, iPSC) line from the FVB/N strain-derived mouse embryonic fibroblasts (MEFs). The exposure of MEFs to human , , , and (OSKM) transgenes via lentiviral transduction resulted in complete reprogramming. The N9 iPS cell line demonstrated all the criteria of a typical mouse PSC line, including normal colony morphology and karyotype (40,XY), high replication and propagation efficiencies, expression of the pluripotency-associated genes, spontaneous differentiation to three germ lineage-derived cell types, and robust potential of chimeric blastocyst formation. Taken together, using human OSKM genes for transduction, we report, for the first time, the successful derivation of an EGFP-expressing iPS cell line from a genetically nonpermissive transgenic FVB/N mouse. This cell line could provide opportunities for designing protocols for efficient derivation of PSC lines from other nonpermissive strains and developing mouse models of human diseases.

The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
Cells from adult organisms that have been reprogrammed into a pluripotential state similar to that of EMBRYONIC STEM CELLS.
Methods of implanting a CELL NUCLEUS from a donor cell into an enucleated acceptor cell. Often the nucleus of a somatic cell is transferred into a recipient OVUM or stem cell (STEM CELLS) with the nucleus removed. This technology may provide means to generate autologous diploid pluripotent cell for therapeutic cloning, and a model for studying NUCLEAR REPROGRAMMING in embryonic stem cells. Nuclear transfer was first accomplished with frog eggs (RANA PIPIENS) and reported in 1952.
Procedures used for the induction of CELLULAR REPROGRAMMING to change the terminal phenotype of a cell, such as the generation of INDUCED PLURIPOTENT STEM CELLS from differentiated adult cells by the forced expression of specific genes.
