A photo of human embryonic stem cells (the cell colonies in the center). Spindle cells surrounding the stem cell colony are MEFs. 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.

Multiscale Electrophysiology Format (MEF) was developed to handle the large amounts of data produced by large-scale electrophysiology in human and animal subjects. MEF can store any time series data up to 24 bits in length, and employs lossless range encoded difference compression .
A blastoid is an embryoid, [1] a stem cell-based embryo model which, morphologically and transcriptionally resembles the early, pre-implantation, mammalian conceptus, called the blastocyst. The first blastoids were created by the Nicolas Rivron laboratory [ 2 ] [ 3 ] by combining mouse embryonic stem cells and mouse trophoblast stem cells.
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 ...
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 ...
Mesenchyme (/ ˈ m ɛ s ə n k aɪ m ˈ m iː z ən-/ [1]) is a type of loosely organized animal embryonic connective tissue of undifferentiated cells that give rise to most tissues, such as skin, blood or bone. [2] [3] The interactions between mesenchyme and epithelium help to form nearly every organ in the developing embryo. [4]
The anterior/posterior axis in the mouse embryo is specified by two signaling centers. In the mouse embryo, the egg forms a cylinder with the epiblast forming a cup at the distal end of that cylinder. The epiblast is surrounded by the visceral endoderm, the equivalent of the hypoblast of humans and chicks.
