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 ...
For example, $225K would be understood to mean $225,000, and $3.6K would be understood to mean $3,600. Multiple K's are not commonly used to represent larger numbers. In other words, it would look odd to use $1.2KK to represent $1,200,000. Ke – Is used as an abbreviation for Cost of Equity (COE).
In 2013, Araki et al. attempted to reproduce the conclusion obtained by Zhou et al. using a different procedure. They took cells from a chimera that had been grown from IPSC clones and a mouse embryo, this tissue was then transplanted into syngenic mice. They conducted a similar trial using ES cells instead of IPSC clone and compared the results.
EBs are differentiation of human embryonic stem cells into embryoid bodies comprising the three embryonic germ layers. They mimic the characteristics seen in early-stage embryos. They are often used as a model system to conduct research on various aspects of developmental biology.
As implied by the name, this specification occurs based on where within the embryo the cell is positioned, it is also known as positional value. [24] This was first observed when mesoderm was taken from the prospective thigh region of a chick embryo, was grafted onto the wing region and did not transform to wing tissue, but instead into toe tissue.
The earliest specification in mouse embryos occurs between trophoblast and inner cell mass cells in the outer polar cells and the inner apolar cells respectively. These two groups become specified at the eight-cell stage during compaction, but do not become determined until they reach the 64-cell stage.
