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: http://goo.gl/zaRYdj

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 …

There are a wide range of interactions between ‘science’ and ‘the public’. Examples range from visiting a museum, or indulging in a science-related hobby, to reading a newspaper article about a breakthrough in the techniques of therapeutic cloning. Many of these interactions could be said to be ‘passive’. This unit explores the practicalities of the public becoming more ‘active’ in the direction of science practice by ‘two-way’ interactions, with dialogue taking place between science and some part of ‘the public’, This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University.

New stem cell 'milestone' revealed

One of the obstacles to human cloning has been cleared by scientists who have successfully used skin to generate embryonic stem cells.

The advance, described as a “milestone”, is expected to aid the development of stem cell therapies that avoid fertilised human embryos.

But since it employs a cloning technique it is certain to fuel controversy over “Brave New World” science.

The US scientists said they were not interested in cloning humans and did not believe their methods could successfully be used in this way.

But the therapeutic cloning technique they employed would also be the start of the process of making duplicate humans.

It is the first time scientists have managed to create human embryos through cloning developed enough to provide stem cells.

The same somatic cell nuclear transfer (SCNT) technique was employed by researchers at the Roslin Institute in Edinburgh to produce Dolly the Sheep, the first mammal cloned from an adult cell.

During SCNT, a donor cell nucleus is transferred to an egg cell whose own nuclear DNA has been removed. The egg develops into an early-stage embryo that is a clone of the donor, containing the same genes.

Stem cells taken from the embryo are “pluripotent”, having the ability - with the right coaxing - to mature into any kind of tissue in the body, from brain to bone.

In the new study, reported in the journal Cell, scientists transferred nuclei from human skin cells into human egg cells.

They generated “blastocysts”, early embryos consisting of a cluster of 150 cells, from which human embryonic stem cells (hESCs) were obtained and grown in the laboratory.

Scientists have previously cloned monkey embryos and mined them for stem cells, but until now been frustrated in their attempts to do the same with humans.

Lead researcher Professor Shoukhrat Mitalipov, from Oregon Health and Science University, said the finding offered new ways of generating stem cells for patients with dysfunctional or damaged tissues and organs.

“Such stem cells can regenerate and replace those damaged cells and tissues and alleviate diseases that affect millions of people,” Prf Mitalipov said.

The stem cells demonstrated an ability to convert into several different cell types, including nerve, liver and heart cells.

Prof Mitalipov added: “Furthermore, because these reprogrammed cells can be generated with nuclear genetic material from a patient, there is no concern of transplant rejection.

"While there is much work to be done in developing safe and effective stem cell treatments, we believe this is a significant step forward in developing the cells that could be used in regenerative medicine.”
