"Therapeutic cloning is to produce stem cells from the patient by the following procedure. It takes a cell endorsed anyone obviously need not be a stem cell. We made the nucleus with the chromosomes inside and throw everything else. Then get an unfertilized egg (preferably human but possibly animal) and pull its core with their chromosomes. We put the core of the patient's cells into the egg. Get an egg and a little confused, because it has not been fertilized by a sperm, but nevertheless has already completed all the pairs of chromosomes. Somehow, he gets the egg begins to divide. And this is what we wanted: the descendants of this egg are stem cells that have the same DNA as the patient (on chromosomes) and therefore will not cause rejection when injected. Possibly unnecessary clarification: in principle this is not related to genetic engineering, because genes do not change at all, changing the entire cell nucleus.
The list of devastating diseases that are believed to cure or alleviate may be using similar techniques include diabetes, cirrhosis, leukemia, osteoporosis, burns, Alzheirmer, Parkinson, Huntington, quadriplegia, some types of cancer, some heart and back ailments , and others.
Some arguments made by opponents of these techniques:
"It's an abortion, the murder of an innocent. "In the future
could find other cures that did not require stem cells, or that use stem cells that were not eggs, or may be given drugs to stimulate neurons or other cells to reproduce. Already been achieved "reprogram" stem cells from human bone marrow into nerve cells, and make certain nerve cells of rat stem cells. Making clones
"undermines human dignity, even if not meant that these embryos develop. "There will
women mistakenly believe that abortion is helping science, or that are justified in this.
Supporters of developing these techniques are not leave convinced by these reasons because:
-Researching these techniques will help you find exactly substitute procedures that would otherwise go undiscovered or be found later.
"In principle you could use other human stem cells such as bone marrow or umbilical cord. But in practice there are problems with both human and animal. Adult stem cells lose capacity, and those most amenable to these maneuvers are the eggs.
"Do not try to clone humans, these embryos have no chance to develop their own (would be implanted in a uterus). "The embryos used
so far come from experiments in vitro fertilization unfeasible, either because they lack chromosomes and could never develop, or because after a genetic analysis knows that these embryos would grow to have some deadly disease. It would therefore be legally abort if they were in a womb, and it seems logical that the laboratory is destroyed in a lawless.
"There is research that can be done with animals, but others are not. In particular, there are many human diseases without animal equivalent. Authorizing committees to conduct experiments in each case decide whether the use of human embryos is justified or not.
difficult to predict the future but it is interesting to note that all technical committees are for research adequately controlled. The story does not guide us, because human dignity is very capricious, remember the old arguments about dissection of corpses, blood donations, or the legalization of abortion and cannibalism or the death penalty. Pretend you never will abuse the new technology would be to ignore human nature, but to say that in the future things will be accepted now seem questionable would be oversimplifying the situation. The only thing that seems clear is that it is easier to solve technical problems have to agree. "
