Perspective of human cloning

Many people are worried about the prospect of a human being born in the name of science.

Although it has just been heard, human creation is like a blasphemy, going against morality and moral conception from Asia to Europe, experts say, biologically, still Can create a true human version without heavy pain. However, even if the issue of morality is left aside, the internal resources used to create a true person are still a difficult barrier to overcome.

Since the 1950s, when researchers successfully cloned a frog, experts have since "produced" dozens of animal species, including mice, cats, sheep, pigs and cows. In each case, they are always faced with problems to be overcome, Fox News quoted Dr. Robert Lanza of Advanced Cell Technology, a biotechnology firm, which works in the field of cellular therapy to treat disease. for people and animal clones. With mice, researchers can use thousands of eggs, and conduct multiple experiments to find ways to handle errors during the process. 'It's like a counting game , ' said Dr. Lanza. However, in the case of primates, eggs are a very rare source of raw materials and are not easily available but perform experiments.

In addition, they cannot simply apply what they learn by cloning mice or cows to humans. For example, animal cloning requires researchers to first remove the egg cell nucleus. When doing this, they simultaneously removed all the proteins needed to support cell division. This is not a problem in mice, because the created ovule is still capable of producing these proteins again. However, primates cannot do that, and the researchers think this is one of the reasons why the monkey duplication effort failed. And yet, animal cloning often leads to a variety of genetic abnormalities, preventing the implantation of the uterus, or the elimination of embryos, or the subject of death immediately after birth.

These abnormal conditions are quite common when cloning animals because the implanted embryos have only one parent instead of both as in the case of natural conception. This means that the molecular process called 'genome imprint' does not take place in the correct sequence in cloned embryos. Having trouble at this stage can lead to many times larger than normal, hindering the process of blood circulation to the fetus. In an experiment, Dr. Lanza and colleagues cloned a species of cattle called banteng bison. And the animal was born with twice the normal size, forcing the expert team to make it a pleasant death.

In addition to the usual moral issues, extremely high mortality rates and the risk of developing deformed deformities make the cloning work face intense opposition from society.'It's like throwing your child on a rocket and knowing that the probability of explosion is 50-50. Clearly unethical, ' concluded Dr. Lanza.
