Sentences with phrase «nuclear transfer into»

Somatic cells can be reprogrammed either by nuclear transfer into oocytes or by fusion with embryonic stem (ES) cells.

Not exact matches

Although Ghana has no military use of its nuclear assets, options for scientific research into modern nuclear propelled submarine and aircraft carrier ships, design and development of same technology and its transfer from partner OECD for its military use are imminent.

In somatic cell nuclear transfer, a nucleus from a mature body cell is transplanted into an egg cell without a nucleus.

The nuclei are inserted into egg cells which have had their original nucleus removed, a process called nuclear transfer.

«We think that differentiation is a way that opens some doors and makes it easier for nuclear transfer programming to go back into embryonic stem cells.»

However, this method raises the following problem: in every nuclear transfer, a small number of defective mitochondria are transferred into the healthy egg cell.

Tom Clements, southeastern nuclear campaign coordinator of Friends of the Earth, said the fuel in pool No. 4 was hotter than in the plant's other pools because it had more recently been transferred into the pool.

Using a process called somatic cell nuclear transfer (SCNT), a team from Oregon Health & Science University (O.H.S.U.) in Portland implanted the contents of individual skin cells from adult male rhesus macaques into each of 304 macaque egg cells stripped of their genetic material.

Of the 29 early embryos created by somatic - cell nuclear transfer and implanted into various ewes by Roslin researchers, only one, Dolly, survived, suggesting that the technique currently has a high rate of embryonic and fetal loss.

The new finding brings a measure of closure to a story that first rocked the science world in February 2004, when Hwang and colleagues at Seoul National University announced they had cloned a female donor's cell by transferring its nucleus into one of her egg cells stripped of its nucleus in a procedure known as somatic cell nuclear transfer (SCNT), and harvested embryonic stem cells from the resulting fusion.

Enriched uranium oxide is formed into rods and water is used both as a coolant, flowing through the reactor core to transfer heat away, and as a moderator, slowing down neutrons released by fission so that they promote further nuclear reactions.

Opponents said that the measure should have banned somatic cell nuclear transfer; it criminalized only the «implantation» of an embryo into a woman to create a human clone.

But the favored reprogramming technique, somatic cell nuclear transfer (SCNT), otherwise known as research cloning, is fraught with ethical pitfalls as well as technical difficulties because it entails creating a human embryo by inserting an adult cell nucleus into an ooctye.

One way to create such cells is through somatic cell nuclear transfer (SCNT), in which the nucleus of a patient's cell is inserted into an egg cell from which most of the DNA has been removed (ScienceNOW, 19 June).

Dolly was cloned using the technique of «somatic cell nuclear transfer,» when a nucleus from an adult cell is transferred into an unfertilized egg that has had its nucleus removed, and is then shocked with electricity to start cell growth.

Animal cloning uses a process known as somatic - cell nuclear transfer, where the nucleus from an adult (donor) cell is transferred into an egg (host) cell lacking a nucleus.

While Gurdon's tadpoles did not survive to grow into adult frogs, his experiment showed that the process of specialization in animal cells was reversible, and his technique of nuclear transfer paved the way for later cloning successes.

There are lessons that we can learn from somatic cell nuclear transfer where the somatic cell brings accompanying mitochondrial DNA (mtDNA) into the egg.

The Society believes that research involving the transfer of a human nucleus into an animal egg will lead to important new knowledge about cell nuclear replacement (CNR) technology and, if it were to prove possible to produce embryonic stem cells by this route, would increase understanding of how to programme these cells to develop into different tissue types.

Our recommendations include better enforcement of existing regulations, expedited transfer of nuclear waste into dry casks, strengthened reactor security requirements, and higher safety standards for new plants.
