The efficiency of nuclear transfer remains extremely low (<2%) and high rates of perinatal mortality are observed, particularly when adult somatic cells are used as donor karyoplasts. This ...

Table 1 Full-term development of reconstructed oocytes Our results demonstrate that cloning using adult somatic cells is not restricted to female or reproductive cells. Thus, it should be possible ...

The cloning of embryos for generating stem cells ... In this slide show showing somatic cell nuclear transfer, as it's also known, we explain how we clone egg cells to create embryonic stem ...

The technique consists of taking an enucleated oocyte (egg cell) and implanting a donor nucleus from a somatic (body) cell. It is used in both therapeutic and reproductive cloning. In 1996, Dolly the ...

The process involves transferring the nucleus of a donor cell into an enucleated egg cell, which then develops into an embryo and is implanted into a surrogate mother. Therapeutic cloning, also known ...

But critics say the work raises ethical concerns by bringing the world closer to human cloning. Qiang Sun of ... Zhong Zhong was created by somatic cell nuclear transfer Zhong Zhong was born ...

A decade ago, Woo-Suk Hwang was a pioneering researcher at Korea’s Seoul National University, a puzzle solver who cracked one of the most dazzling challenges in modern biology: human somatic cell ...
