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 ...

This is an embryo 4 hours after fertilization before it has undergone MBT. 3 layers are present: yolk syncytial layer (YSL), enveloping layer (EVL), and deep cells (DEL). Before the embryo undergoes the midblastula transition it is in a state of fast and constant replication of cells. [1] The cell cycle is very short. The cells in the zygote ...
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 blastula (from Greek βλαστός (blastos meaning sprout)) is a hollow sphere of cells known as blastomeres surrounding an inner fluid-filled cavity called the blastocoel. [ 1 ] [ 2 ] Embryonic development begins with a sperm fertilizing an egg cell to become a zygote , which undergoes many cleavages to develop into a ball of cells ...
Mouse embryo fibroblasts (MEFs) originated from the double knock-out mice, which do survive in culture even though there is a complete absence of fusion, but parts of their mitochondria show a reduced mitochondrial DNA copy number and lose membrane potential.
The embryo map is a sequence of 3-D images, or slices of 3-D images, of the developing embryo which, if viewed rapidly in temporal order, forms a time-lapse view of the growing embryo. The embryogenic tree is a diagram which shows the temporal development of each of the cell lines in the embryo.
