In somatic cell nuclear transfer, a nucleus from a mature body cell is transplanted into an egg cell without a nucleus.
The method, called somatic cell nuclear transfer (SCNT), replaces the DNA in an egg cell's nucleus with the genetic material from the nucleus of a skin cell, then tricks the egg cell to start dividing as if it had been fertilized with sperm.
Zhong Zhong and Hua Hua are the product of somatic cell nuclear transfer (SCNT), the technique used to create Dolly the sheep over 20 years ago, in which researchers remove the nucleus from an egg cell and replace it with another nucleus from differentiated body cells.
His group began with 242 eggs, but after removing the eggs» nuclei and swapping in those of somatic cells, the investigators produced only 30 blastocysts (week - old embryos), from which they coaxed just one stem cell line into being.
In somatic cell transfer, the nucleus of an egg is replaced with the nucleus from another cell that contains the full genetic information of an individual.
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.
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.
SCNT is a technique wherein the nucleus from a somatic cell (an adult cell that is not a sperm or egg, i.e. not the gametes) is implanted into an enucleated egg cell which can then be implanted into, and develop in, a surrogate mother, and potentially become an adult organism.
SCNT is a technique wherein the nucleus from a somatic cell (an adult cell that is not a sperm or an egg) is implanted into an enucleated egg which can be implanted into, and develop, in a surrogate mother, and potentially become an adult organism.
