The main challenges for SCNT cloning of human embryonic stem cells

human-cloning1

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 …

Adult human therapeutic cloning of embryonic stem cells by SCNT

Human-SCNT1

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) and reported the advance in the Chung, et …

Stem cell story of the year: human therapeutic cloning

Knoepfler-art-Human-Cloning

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. …

Janet Rossant, ISSCR President, on her goals, cloning, non-compliant clinics, iPS cells, and future of field

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 …

Fertility clinic floats idea of human cloning for infertility

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 …

Natalie DeWitt Must-Read Comment on Cell Cloning Paper Mishap

Natalie-deWitt

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 …

Stem cell field stumbles on cloning dialogue

circle-the-wagons-cover-tbnl1

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 …

Deja you: human cloning generally legal in the US

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 …

5 human therapeutic cloning talking points dissected

Knoepfler-art-Human-Cloning

Yesterday’s report of human therapeutic cloning to make embryonic stem (ES) cell lines is a big deal. I support the work and I believe it is very important. People’s reactions to it vary wildly depending on their agendas of course. This post is a no-nonsense overview of the main points. My overall point. This is …
