Human Stem Cells Created by Cloning

Breakthrough sets up showdown with induced adult lines.

It was hailed some 15 years ago as the great hope for a biomedical revolution: the use of cloning techniques to create perfectly matched tissues that would someday cure ailments ranging from diabetes to Parkinson’s disease. Since then, the approach has been enveloped in ethical debate, tainted by fraud and, in recent years, overshadowed by a competing technology. Most groups gave up long ago on the finicky core method — production of patient-specific embryonic stem cells (ESCs) from cloning. A quieter debate followed: do we still need ‘therapeutic’ cloning?

Therapeutic Cloning Survey

Hey everyone, sorry to be a nuisance but I just wanted to bump this up so that I can get as many responses as possible since I will be closing the survey in a week or two! I am only 7 responses away from my goal, though I would love more!

I’m doing some research on ‘therapeutic cloning’ for one of my modules as part of my degree in molecular genetics at the University of Dundee in Scotland. I would really appreciate if you could take a few minutes out of your day to answer some questions about therapeutic cloning. The survey isn’t too long and I’m getting some interesting responses so far. Thanks a million everyone!!

Here is the survey:

Classic Miranda, 2006: IT’S ironic that the most passionate proponents of embryo cloning are women such as Senators Natasha Stott Despoja and Kay Patterson. As the therapeutic cloning bill is debated in the House of Representatives this week, feminists are right behind it. Yet where will scientists get the thousands of human eggs they need for experiments? Few women will line up for debilitating hyper-ovulation hormones just to donate eggs for ethically questionable research. As Women’s Forum Australia pointed out in its Senate inquiry submission, egg shortages will leave women open to exploitation and raise the unsavoury prospect of harvesting eggs from dead women or aborted female foetuses.
—  Or they’ll come from woman donating their leftover eggs from IVF treatment. Otherwise those eggs end up going down the sink anyway.
Cloning - The ethical perspective

Reproductive cloning is only one of the many forms of cloning: DNA cloning and therapeutic cloning also exist

But it is reproductive cloning that has generated the most controversy, since it is a technology used to generate an animal that has identical nuclear DNA as another currently/previously existing animal (Dolly was made by reproductive cloning technology)

Therapeutic Cloning

I’m doing a presentation about ‘therapeutic cloning’ for one of my modules at university. I’ve created a short survey which should take no longer than 5 minutes and I would really appreciate it if you could take a few wee minutes to fill it out for me?

The survey can be found at the link above!!

The scientists involved in the new study, based in Los Angeles and South Korea, showed that the cells they harvested could develop into any of the major tissues found in a human embryo, giving them the “potential for applications in a range of therapeutic contexts.”

Therapeutic cloning describes the concept of using a subject’s DNA to create stem cells tailored for their own body, cells that could then be used to cure diseases or repair tissues in the original donor.

But therapeutic cloning raises ethical questions. In 2005, The United Nations General Assembly adopted a non-binding declaration that called for the ban of human cloning on the grounds of dignity. And the United States government has restricted the use of federal funds for research into therapeutic or reproductive cloning.

By fusing DNA from skin cells with human eggs, the scientists were effectively creating a human embryo. While they harvested the cells during the early stages of cell multiplication, the resultant embryo could theoretically have been implanted into a host and brought to term, making it an actual human clone.

The authors of the study choose not to address this issue, discussing instead the cells’ potential for helping humans produced in the traditional manner.

Benefits of Therapeutic Cloning in Stem Cell Science

Therapeutic cloning refers to a process of utilizing SCNT or the somatic cell nuclear transfer for the production of cells exactly matching the patient. The procedure involves the combination of the patient’s enucleated egg and somatic cell nucleus.  Therapeutic cloning Vs Reproductive …

You know, I’ve always thought the concept was interesting! Thinking we could have identical (or, almost identical) copies of something sounds absolutely amazing! I don’t think it’s something that should be done in mass quantities though. 

From what I read here in this article (which is really interesting!), cloning stuff works but not often, like, not often at all, and it can cause a lot more problems than it can good things. I definitely wouldn’t put a human through it and honestly if they’re gonna do this with animals they better do their best it’s not harmful (which well, it oftentimes IS). It’s a cool concept but atm I wouldn’t consider it a good thing because there seems to be more cons than pros. At least with the reproductive cloning.

Therapeutic cloning seems like a good idea (that’s cloning an embryo so embryonic stem cells can be grown to produce any sort of tissue that can be used to help injured/sickly people, and also study diseases without actually looking at them within a person). I mean, it can help us learn so much and help people even more so. I get that the problem of destroying an embryo is a big red flag to a lot of people but I’m not going to get into that unless someone specifically asks. There are a few drawbacks and I think that specific type of cloning should get more research but, it could be used for good, and you aren’t completely cloning an individual to make another one.
