generally speaking, cell nuclear transfer consists in replacing an embryonal cell's genes which nucleus was removed by the genes of an adult cell.
Since then, many researches have clonated different animal species such as mice, pigs, horses and cows. equally, there has been scandals for example the case of Woo Suk Hwang who in 2004 announced that he cloned a human embryon, but it turned out to be false and of course there is the ethic dilemma over its use.
Human clonation is supossed to be useful to develop new healthy cells or tissues and in this way help people treat incurable diseases such as parkinson by using the cellular reprogramming technique which consists in inserting one or more genes within an adult cell, for example the skin in order these elements to be the ones which start reprograming internally that cell with no need to use an embryo or an ovule, leaving behind any possible ethic debate. from this point of view clonation seems absolutely positive, the problem is when human ambition could raise the idea of clonating a whole human being. would this be ethic? would this person be as normal as you and me? some religious people think that cloned humans will have no soul, what do you think about this? would you like to have another you?
Catalina, I´m all for clonation when it is directed to help to cure health problems; nevertheless, I think that society is not ready to recieve cloned human beings, and I´m not talking from a religious perspective, but for a practical point of view. What would be the purpose of cloning human being beside using them as a help in terms of health. Or would they have their own lives?
ReplyDeleteI have deeply felt concerns about cloning, particularly human cloning. I fear that this relatively new science is still too risky and unpredictable; experiments with cloning a human might result in serious defects or health problems for the cloned subjects. Moreover, I worry that the ability to clone a person might be abused by some who would spend a great deal of money to creates a genetically perfect child, selecting certain traits and discarding others. Of course, this could benefit people with incurable diseases. Scientists and doctors have long intervened in the creation of new life, such as using various fertility treatments to help people have babies who otherwise couldn't, which is really awesome! I really wish cloning were used appropiately and for people who really need it.
