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 the early mouse embryo, the sister cells of each division remain connected during interphase by microtubule bridges. [7] The different cells derived from cleavage, up to the blastula stage, are called blastomeres. Depending mostly on the amount of yolk in the egg, the cleavage can be holoblastic (total) or meroblastic (partial). [8] [9]
The first cells of the embryo to undergo EMT and form mesenchyme are the extra-embryonic cells of the trophectoderm. These migrate from the body of the blastocyst into the endometrial layer of the uterus in order to contribute to the formation of the anchored placenta .
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.
