KIE: A medical team at Monash University in Australia, which had already been implanting in patients embryos developed from eggs donated by other women, has now achieved a successful pregnancy following implantation of a previously frozen embryo. The group's work has been under the scrutiny of a...

(a13-year-old female known as Celia), biologists took cells from her skin and ears. An earlier cloning attempt to use the skin cells failed. But the latest attempt involved the creation of 439 cloned embryos. Of these cloned embryos, 57 were put into the female domestic goats, but only ...
more than 40 human children and mammals have been born with the use of this techni ue, and in this sketchy review, we discuss the current status of the clinical application, ethical concerns, preclinical researches and prospects of ooplasmic transfer. RESEA CHOVE VIEWOFOOPLA MIC T AN FE Wh ...
Then patients have to make a decision about the spare embryos. Step two: the researchers should communicate with the patients after they sign the frozen embryos informed consent and choose to give up embryos for research purpose. Finally, the researchers and donating couple sign informed consent ...
This is primarily due to its ability to generate a substantial quantity of embryos within the in vivo system, thereby minimizing the adverse effects typically associated with the in vitro environment on oocyte development. Additionally, AFF technology eliminates the need for elaborate laboratory ...
However, the adaptive changes of fully formed organisms differ radically from the responses of vertebrate embryos, foetuses, and larvae to space flight. Development is associated with active cell proliferation and the formation of organs and systems. The instability of these processes is well known. ...
Unfortunately, IVF pregnancy results are low and the treatment is expensive and associated with various medical risks for both the mother and the child. The progress in IVF has so far been focused on the improvement of the developmental potential of in vitro embryos, while the possibilities for ...
