The process of somatic cell nuclear transfer involves two different cells. The first being a female gamete, known as the ovum (egg/oocyte). In human SCNT experiments, these eggs are obtained through consenting donors, utilizing ovarian stimulation. The second being a somatic cell, referring to the cells of the human body.
Somatic Cell Nuclear Transfer (SCNT) is the process by which the nucleus of an oocyte (egg cell) is removed and is replaced with the nucleus of a somatic (body) cell (examples include skin, heart, or nerve cell). The two entities fuse to become one and factors in the oocyte cause the somatic nucleus to reprogram to a pluripotent state.
Reproductive cloning generally uses "somatic cell nuclear transfer" (SCNT) to create animals that are genetically identical. This process entails the transfer of a nucleus from a donor adult cell (somatic cell) to an egg from which the nucleus has been removed, or to a cell from a blastocyst from which the nucleus has been removed.

The first mammal to be cloned — Dolly the sheep — was created in 1996 using a technique called somatic cell nuclear transfer, or SCNT, where scientists essentially reconstruct an unfertilized ...
Diagram of SCNT process. In somatic cell nuclear transfer ("SCNT"), the nucleus of a somatic cell is taken from a donor and transplanted into a host egg cell, which had its own genetic material removed previously, making it an enucleated egg. After the donor somatic cell genetic material is transferred into the host oocyte with a micropipette ...
In the case of mammals such as the woolly mammoth, scientists are able to edit their cells in a lab and clone them using somatic cell nuclear transfer — the same technology that made Dolly the ...
Dolly (5 July 1996 – 14 February 2003) was a female Finn-Dorset sheep and the first mammal that was cloned from an adult somatic cell.She was cloned by associates of the Roslin Institute in Scotland, using the process of nuclear transfer from a cell taken from a mammary gland.
The somatic nuclear cell transfer technique is a well-known cloning method that has been used for years but focuses on species that are thriving rather than endangered or extinct species. This technique usually uses a single somatic donor cell with a single manipulation and inserts it into a recipient egg of the species of interest.
