If you’ve been paying attention to the stem cell world, you’ll remember Woo Suk Hwang, who nearly derailed the future of stem cell research by very publically proclaiming that he had made human embryonic stem cells by somatic cell nuclear transfer (SCNT). No, this has nothing to do with Shoukhrat Mitalipov’s report of successful generation …

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. …

De-extinction is big right now and some of the extinct target creatures are big too like the woolly mammoth. “Let’s bring back these extinct creatures”, say proponents. Wouldn’t it be cool? I have to admit seeing a woolly mammoth, mastodon, or saber tooth tiger would be cool, but such efforts would not be without consequences …
In late 2010, Nicholas Wade, then a frequent science writer for the New York Times, wrote a frankly nasty piece on the stem cell field that was insulting and oversimplistic. Now today we have yet another piece in the NYT by Wade on stem cells, and he mostly makes a mess of it again, with …

There is a lot of talk about cloning celebrities so could we be seeing John Lennon again in the form of a clone? If a Canadian dentist named Michael Zuk has his way, the late Beatle may be back. In his quest to get back Lennon, Zuk reportedly purchased an old molar that once had …
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 …
Occasionally I call out a particularly important comment by a reader on a major issue and today it is commenter Natalie DeWitt (see my earlier interview with her about her experiences at Nature’s The Niche) who has contributed a particularly insightful, knowledgable comment on my recent perspective piece the Cell cloning paper mishap. Many in the …

Is it really deja vu all over again with allegations of potential wrongdoing in a paper on human cloning? “Say it isn’t so!”, is basically the universal reaction I’m getting from people in the stem cell field. Well, sadly it seems to be so folks. What’s going on? Allegations have emerged on a website called …

We had the big news last week that for the first time ever, human embryo cloning (aka “therapeutic cloning”) worked to produce apparently normal embryonic stem cells. I posted about it a few times here, here, and here. I have tried my best to be factual, open minded, and realistic about the issues. Frankly, the …
One of the great areas of confusion over the human cloning development this week is whether human cloning is legal or illegal. With few exceptions, human cloning in general is legal in the US. Update: in 2020 it still appears that reproductive human cloning is legal in the US. It just hasn’t gotten that much …
