L
to American company/signature Advanced Cell Technology (ACT) convulsionó to the scientific world: it announced that clonó successfully human embryos ?with therapeutic aims?. According to the company of genetic investigations, the objective is to obtain cells mother that help to cure diseases. Its intention - according to ACT- it is not to create complete human beings.
The announcement was received with critics in average American politicians and between some investigators, who understand that this step supposes to open the door completely to the human clonación.
Pero ACT is a private company reason why it is not put under the restrictions imposed by the government of EE.UU in the investigation with embryonic cells.
Jose Cibelli, vice-president of investigation of the company, declared that their works confirm that ?the reprogramming of the human cells is possible? and that a new field is opened to the treatment of the diseases.
The cells mother, that are mainly in the embryos, can give rise to any type of weave of the human body if they are cultivated, which turns a potential treatment transplants and to regenerate the weaves died because of the cancer, the disease of Alzheimer or Parkinson, among others.
But they will only be totally compatible with the person who needs them when they come from a clone of the own patient, because then the immunological system will recognize them like own.
ACT, a small company with seat in Worcester (Massachusetts), took in EE.UU the step of clonar embryonic cells with the genetic material of another person, by means of a denominated procedure ?nuclear transference?.
In this procedure, very similar to which was used to clonar to the Dolly ewe, the genetic material retires (ADN) that has a human ovum and it is replaced by DNA of an adult cell, for example of the skin, that belongs to another person. The result, after several processes, is that the nucleus of that new cell reprograma and is begun to behave like an embryo in its different phases from development, one of which will produce the compatible cells mother with the person who contributed her DNA to the process.
Michael West, president of the company, rejected the possibility that their experiments take to the complete clonación of an alive being. Nevertheless, numerous opposite scientists to the human clonación affirm that those new embryos, if they are implanted in the uterus of a woman, can upon maturity take the creation of a human being, who would be a perfect copy of another person.
The preoccupation in this field was made patent summer the past, when the Italian andrólogo Severino Antinori announced its intention to create by this same procedure a complete human being.
The advance announced yesterday is plus a challenge to the American legislation that to the difficulties of the technology. Their investigators in a while took this step in which in EE.UU a legal emptiness with respect to the clonación of embryos exists, since its prohibition on the part of the Congress was left braking by the attacks of the 11 of September.

The Church, first in condemning
The Catholic Church hard condemned the techniques of human clonación with therapeutic aims spread yesterday by the North American company Advanced Cell Technology.
The clonación is ?an abusive and morally reprochable? act, observed monsignor Mauro Cozzoli, educational of moral theology of the Lateranense University of Rome.
The fact that it is made with therapeutic aims ?aggravates the opinion? since, it explained, it is not possible to be generated a human individual with the objective ?to suppress it in benefit of another one?. For the Church an embryo, even of few cells, although ?made?, has estatus of human individual.
For two days, almost anticipating the announcement of the ACT, the Pope - in a message to the French social weekly it had criticized the experimentations on embryos and had exhorted to the caution in the field of the investigation on the estaminales cells.
?No man exists, neither human authority, nor science, nor medical, social, economic, moral indication that can exhibit or give valid legal title - it had said remembering the education of the Church to arrange deliberately in direct and of an innocent human life, that is to say, to have this one in view of their destruction, is like average aim or obtaining an objective, that in itself is not perhaps absolutely ilegítimo?.
?The clonación of a human individual - monsignor Cozzoli- said is an abusive and morally reprochable act, because human offends the truth of procreating, who must happen through encounter and the two fusion of gametas, in trusteeship of the identity, of the unicity, the dignity and also of the health of the human individual. The clonación denies and it does not respect all this. It is index also of a power will on the life?.
?The therapeutic purpose of a human clonación not only does not attenuate this opinion but it aggravates it, because it is not possible to be generated to a human individual using it soon and suppressing it in benefit of another individual. An obtained human embryo by clonación is even already an individual and as so it deserves the recognition and the respect due to the person?. (ANSA)
From the ewe ?Dolly? to today
The first clonación of a human embryo, announced yesterday opens a new scientific chapter, but a new controversy wakes up on the ethical limits of the investigation.
Next some of the main stages of the process that it preceded to the announcement made yesterday:
* 1994. First progress in the detection of the cell mother of all the cells, in degree to generate each type of weave and organ: the group of Peschle identified the gene KDR, that controls the receiver of the factor of growth of the walls of the blood vessels.
* 25 of February of 1997. The ewe Dolly, first unit of equal organism to the one of another one is born, in which both genetic patrimonies are absolutely identical.
* 1998. In June the first male animal is clonado, a mouse, by a scientist of the university of Hawaii; in December, in Japan, by a cow eight identical bull calves reproduce.
* 1999. The group of Peschle discovers the estaminales cells of the blood.
* October of 1999. Investigator Cesare Galli announced to have clonado in Cremona, Italy, the Toro Galileo.
Shortly after a decree by the then minister of the health Rosy Bindi is sanctioned that prohibited the clonación.
* 5 of June of 2000. The discovery of emoangioblasto announced.
* 16 of August of 2000. Parallelly to the development of the investigation, the controversy by the ethical problem is generated, but the British government, gives via free to the experiments on the human clonación.
* 21 of March of 2001. The Italian parliament says ?not? to the human clonación and it defines itself clearly in this sense.
The Camera approves definitively, by an ample majority (285 votes to favor, 3 against and 13 abstinences) the protocol of the Council of Europe that prohibits the reproduction ?photocopy? of human beings.
* 25 of November of 2001. A company of genetic investigation of the United States, the Advanced Cell Technology, successful announced to have made the first clonación of a human embryo. (ANSA)
