Human reproductive cloning

4 min read

It was intriguing last week to read about another advance in somatic cell nuclear transfer (SCNT)-based therapeutic cloning of human embryonic stem cells (hESC). The first such work was published last year by Mitalipov’s group from OHSU. This second paper to produce so-called nuclear transfer hESC (NT-hESC) made the important advance to show that it could be done using adult and even old human somatic cells. This is a reproducible technology, which is very important. However, key challenges and concerns remain for human therapeutic cloning …Read More

There have been many interesting developments in stem cells in 2013, but to me the biggest event by far was the first ever successful somatic cell nuclear transfer (SCNT)-based human therapeutic cloning. This approach generated apparently genetically normal human embryonic stem cells (hESC), an astonishing accomplishment. There are two kinds of human cloning: therapeutic and reproductive. The latter is making an actual new person with an identical genome to an existing person. The latter has never been achieved, but some of us are worried it …Read More

Human cloning is not so far-fetched any more.  Cloning of the Star Wars variety where new copies of people (although they would be babies, not adults of course at first) are produced is something I believe that we’ll see in the next 1-2 decades. Why would anyone bother to clone? Fame. Money. Vanity. There are many reasons, all bad in my opinion. Then there is the possibility that human cloning could produce babies for infertile couples. Should human cloning be allowed in the future …Read More

People have been confused about human cloning issues in the last few weeks on a number of levels. The confusion has come along with the excitement, concern, and increased interest in cloning lately since the lab of Dr. Shoukhrat Mitalipov reported a few weeks back in Cell the astonishing feat of successful human embryonic stem cell cloning by somatic cell nuclear transfer (SCNT), a watershed moment for the stem cell field. One area that people seemed confused about is just who is in favor …Read More
