Mouse Embryonic Fibroblasts (MEFs) are a type of fibroblast prepared from mouse embryo. MEFs show a spindle shape when cultured in vitro, a typical feature of fibroblasts. The MEF is a limited cell line. After several transmissions, MEFs will senesce and finally die off.
The primary mouse embryonic fibroblast cells were transferred (the "T") every 3 days (the first "3"), and inoculated at the rigid density of 3 × 10 5 cells per 20 cm 2 dish (the second "3") continuously. [2] The spontaneously immortalized cells with stable growth rate were established after 20 to 30 generations in culture, and then named '3T3 ...

A knockout mouse, or knock-out mouse, is a genetically modified mouse (Mus musculus) in which researchers have inactivated, or "knocked out", an existing gene by replacing it or disrupting it with an artificial piece of DNA.
The tetraploid cells can form the extra-embryonic tissue (placenta, etc.); however, a proper fetus will rarely develop. In the tetraploid complementation assay, one now combines such a tetraploid embryo (either at the morula or blastocyst stage) with normal diploid embryonic stem cells (ES) from a different organism. The embryo will then ...

However, three separate groups were able to find mouse embryonic fibroblast (MEF)-derived iPS cells that could be injected into tetraploid blastocysts and resulted in the live birth of mice derived entirely from iPS cells, thus ending the debate over the equivalence of embryonic stem cells (ESCs) and iPS with regard to pluripotency.
