somatic cell nuclear transfer (SCNT), technique in which the nucleus of a somatic (body) cell is transferred to the cytoplasm of an enucleated egg (an egg that has had its own nucleus removed). Once inside the egg, the somatic nucleus is reprogrammed by egg cytoplasmic factors to become a zygote (fertilized egg) nucleus.

In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell. The technique consists of taking a denucleated oocyte (egg cell) and implanting a donor nucleus from a somatic (body) cell. It is used in both therapeutic and reproductive cloning.

Somatic Cell Nuclear Transfer (SCNT) is performed by transferring a nucleus isolated from a somatic cell (or the intact somatic cell) into an enucleated zygote. This technology was developed and used to produce both homoplasmic and heteroplasmic cybrid models.

2014年11月4日 · Somatic cell nuclear transfer (SCNT) is a technology applied in cloning, stem cell research, and regenerative medicine. Somatic cells are cells that have gone through the differentiation process and are not germ cells. Somatic cells donate their nuclei, which scientists transplant into eggs after removing their nucleuses (enucleated eggs).

Somatic cell nuclear transfer (SCNT), or therapeutic cloning, entails the removal of an oocyte nucleus in culture, followed by its replacement with a nucleus derived from a somatic cell obtained from a patient. Activation with chemicals or electricity stimulates cell division up to the blastocyst stage, and ES cells that are genetically ...

Besides fertilization, an artificial method called somatic cell nuclear transfer (SCNT), or cloning, can also confer totipotency. Dr. John Gurdon was the first to demonstrate that animals could be cloned from differentiated frog somatic cells by SCNT (Gurdon, 1962; Figure 1).

2020年3月12日 · Somatic cell nuclear transfer (SCNT) is a technique which transfers the nucleus of a donor somatic cell to the cytoplasm of an oocyte with its own nucleus removed. The somatic nucleus is reprogrammed in the oocyte, in which it contains the entire genomic information of the somatic cell and progressively develops into the blastocyst.

Somatic cell nuclear transfer (SCNT) is a process by which the nucleus (DNA) is moved from a donor cell to an enucleated recipient cell to create an exact genetic match of the donor. You might find these chapters and articles relevant to this topic. Anne G. Bang, Melissa K. Carpenter, in Essentials of Stem Cell Biology (Second Edition), 2009.

2020年3月27日 · In this review we provide an overview of the current literature on SCNT, focusing on protocol development, which includes early SCNT protocol deficiencies and optimizations along with donor cell type and cell cycle synchrony; epigenetic reprogramming in SCNT; current protocol optimizations such as nuclear reprogramming strategies that can be ...
