Cloning of animals is becoming a big, global business, and Hwang Woo-Suk is a major player here. Hwang Woo-Suk and animal cloning It turns out that this reproductive cloning of animals goes well beyond making duplicates of pets for sentimental customers at $100,000 a copy. Cloning of livestock by agribusinesses is becoming fairly common. Some […]

What is Human SCNT? A new human therapeutic cloning paper is out today, the third in a matter of months. This one is from the lab group of Dr. Dieter Egli published in Nature demonstrating production of nuclear transfer embryonic stem cells (NT-ESCs) from an adult human somatic donor via somatic cell nuclear transfer (SCNT). This
Cloning is cloned again: New Nature Paper is 3rd on Human SCNT Read More »
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

An international team of stem cell scientists has replicated human therapeutic cloning to make embryonic stem cells via somatic cell nuclear transfer (SCNT). The team was led by Drs. Dong Ryul Lee of CHA Stem Cell Institute in Korea and Robert Lanza of Advanced Cell Technology (ACT). They reported the advance in the Chung, et

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.

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

New ISSCR President, Dr. Janet Rossant, kindly agreed to do an interview with me focused on the future of ISSCR, her plans for her tenure, and some key issues in the field. Dr. Rossant is Chief of Research at The Hospital for Sick Children in Toronto. 1. The stem cell arena is a very rapidly changing one
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

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

A few days ago I started a poll on the Mitalipov lab’s human cloning paper in Cell and how people felt about the mistakes in the paper. Are these mistakes a big deal or more just minor glitches? Or somewhere in the middle? Based on the poll so far with 87 respondents, readers of this
