What is therapeutic cloning?

Answer 1

It uses the same procedure as adult DNA cloning to start with. The created embryo will be allowed to grow for around 2 weeks. Its stem cells would be taken and encouraged to grow into a human organ.

Answer 2

· Cloning is to make an exact duplicate of something or someone. in reality. Cloning is actually very different from that point of view. There are three types of human cloning, all three with very different procedures and goals: embryo cloning, adult DNA cloning, and therapeutic cloning. · Therapeutic cloning involves growing replacement organs such as a heart, liver, pancreas, or skin from a sample of a persons DNA. The procedure that would have to be done to accomplish this would involve the use of a human embryo that has been modified by cell nuclear replacement, and the extraction of the embryos stem cells. Therapeutic cloning has not yet been accomplished in a laboratory or clinic. However, a general approach in the future has been put together. It would involve a multiple step process: A DNA sample would be taken from a sick patient; the sample would be inserted into an embryo in place of the original DNA; the embryo would be allowed to grow for around two weeks; the stem cells would be removed from the embryo (this is the destructive and controversial step). · The possible benefits if therapeutic cloning is successful is phenomenal, replacement organs would become freely available to the sick patients and the patients that are dieing because they are in need of a certain type of organ. If scientists become successful, this would most likely take many years of research before the first useable results will be obtained. This means that countless amounts of lives would be saved, and would also greatly increase the quality of life of many others. These people believe that a human personhood comes later in the maturing process inside the woman's womb, or when its brain develops to the point were it becomes conscious of itself, or at birth. Cloning and stem cell research in general is very important ethical hurdle that must be successfully accomplished because this is very important medically and technologically to our rapidly growing society, with this special type of cloning we will be able to live longer, safer, and better lives. Embryos appear to be the only source of stem cells that would have wide potential in therapeutic cloning. Scientists would start with a living embryo, and then replace its DNA. Conservative Christians believe that a human person is present during this time. Many conservative Christians believe that human personhood starts at conception, this would go against therapeutic cloning because the embryo must first be created by cell nuclear replacement, then killed. The stem cells are a unique form of a human cell that can theoretically develop into any organ or body parts of the body; then the tissue or organ would be transplanted into the patient. Then the embryo could be implanted into a female uterus, having a one in four chance of developing into a fetus. However, organs grown from stem cells from a foreign source would have foreign DNA that doesn't match the DNA of the recipient; therefore the recipient would have to take anti-rejection drugs for the rest of their life and could suffer organ rejection at any given time. Even within Christianity, Judaism, and other religions, a range of beliefs exists about when a fertilized ovum becomes a human being. · What about identity? Humans are guaranteed the right to their own personality. What would happen if we overrode those rights by giving them someone else's genetic identity? True, personality is not bounded in someone's genes, but the clone would share any physical appearance or genetic defect of the cloned. · Cloning would also deal with killing embryos. You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. More than 200 embryos, the start of 200 human beings, would die for the sake of just one embryo that would have the same DNA as some one else. · Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transplant organs. This, surely would be immensely beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unconstitutional and would deprive people of the right to reproduce and restrict the freedom of scientists. · Arguments against cloning are also on a perfectly viable side. Primarily, I believe that cloning would intervene with the normal 'cycle' of life. There would be large number of identical genes, which minimizes the chances of mutation, and, in turn, evolution - the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely extinction. Furthermore, cloning would eliminate the uniqueness that each one of us posses. Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as 'objects' rather than people in the society in grand scale. · Scientist haven't 100 per cent guarantee that the first cloned humans will be normal. Thus, this could result in introduction of additional defects in the human 'gene-pool'.

Answer 3

One of the most significant cons involved in therapeutic cloning is the possibility that some of the cells will undergo a mutation, which can result in a tumor. Another drawback is the high cost involved in the procedure.

Answer 4

• some people believe that it's playing god
• some people believe that at that stage the embryo is a person with emotions and feelings
• there are risks to the patient, the effects of the treatment are unknown

Answer 5

One example of therapeutic cloning is in Britain 2007 scientists grew a human heart through the process of therapeutic cloning.

• Remove the nucleus from a egg cell.
• Remove the nucleus from a somatic cell (normal body cell)
• Mix them together
• Leave to stimulate
• That will grow into a blastocyst
• The stem cells are in the inner layer of the blastocyst
• Inject into needy patient

Answer 6

you can create the body part that you need with therapeutic cloning and replace it with the old/injured body part.

Answer 7

Yes, because u can get many diseases

Answer 8

Yes
