| description | When treated with specific transcription factors (Oct4, Sox2, c-Myc and Klf4), some Oct4-EGFP murine embryonic fibroblasts (MEFs) have the properties of induced pluripotent stem (iPS) cells. Such iPS cells have the DNA methylation, gene expression and chromatin state of embryonic stem cells and can form viable chimeras, contribute to the germ line, and generate live late-term embryos when injected into tetraploid blastocysts. |
| molecularNote | A targeting vector was designed to insert an "IRES-EGFP-floxed NEO" cassette (containing an internal ribosomal entry site (IRES), enhanced green fluorescent protein (EGFP) sequence, and a loxP-flanked neo) between the stop codon and endogenous polyA signal of the targeted gene. This construct was electroporated into (C57BL/6 x 129S4Sv/Jae)F1-derived V6.5 embryonic stem (ES) cells. Correctly targeted ES cells were transiently transfected with a cre expressing plasmid to remove the neo selection cassette. |
