From five pairs of twin blastocysts, the fluorograms provided detectable STR profiles for identical peak position between the twin embryos. This is the first report on twinned human embryos to prove monozygocity at the DNA level. Embryo splitting exhibits novel potential for future applications in ...
For example, since human embryos can be frozen and used at a later date, it could be possible for parents to have a child and then, years later, use a cloned, frozen embryo to give birth to an identical twin. Hall is in the in vitro fertilization program at George Washington University...

If a group of cells or even one single cell is separated from the early embryo they (respectively it) can nevertheless “exercise their totipotentiality and produce a clone or twin” (Ashley &Moraczewski, 2001). So, the individuality-charge asks how an embryo can actually be an individual...
This procedure randomly shifts the position of the modules along the cortex without splitting apart the components of the module (Figure S2) (Bethlehem et al., 2017). The resulting null distribution of community partitions preserves the number and size of modules, as well as the spatial ...
Developmental clock compromises human twin model created by embryo splitting. Hum Reprod 2015; 30: 2774-2784Noli, L., Dajani, Y., Capalbo, A., Bvumbe, J., Rienzi, L., Ubaldi, F. M., Ogilvie, C., Khalaf, Y. and Ilic, D. (2015b). Developmental clock compromises human twin ...
Embryos at the 2- to 5- and 6- to 8-cell stage were split into twin embryos. Half the number of blastomeres from donor embryos were removed and inserted into recipient empty zonae pellucidae. After embryo splitting, donor and recipient embryos were cultured in vitro. Development of twinned...
Scientist Clones Human Embryo in Test-TubeAN AMERICAN scientist has cloned a human embryo by splitting it in a test-tube to create identical twin or triplet embryos, in what is believed to be the first reported such experiment.Hunt, Liz...
Cerebral dysraphia (future anencephaly) in a human twin embryo at stage 13 (p 167-177)Cerebral dysraphia was studied histologically and by graphic reconstruction in a twin at stage 13, and comparisons were made with the normal (discordant) twin. The normal, bidirectional closure of the rostral...
