Dolly was born 20 years ago, no human clones and technology … – Observer

For 20 years, the birth of the most famous sheep in the world shook governments and religions, spoke at the end of the world, but after all not born human clones and the technology used has helped to better understand the disease and the beginning of life .

Born on July 5, 1996, the announcement of this strange form of life just happened in February of the following year, condemning “Dolly” to be persecuted by “paparazzi”.

this is because the sheep was born thanks to cloning an adult cell, a feat that has come to be compared to the atomic bomb and sparked in men the fear of being “copied”.

it seems like all the sheep, this sheep was born more equal than the others, it was similar to the donor of the adult cell that has been introduced in another coreless and whose junction resulted in an embryo.

This embryo was then implanted in a “rental sheep” which gave birth to the famous Dolly.

“the creation of Dolly the sheep was and remains a paradigmatic framework of biology and genetics in the world,” said Lusa the bioethicist, Rui Nunes.

for the president of the Portuguese Association of Bioethics, this birth has shown that “science has no limit” and only laments the “historical mistake” that followed from wanting to reduce man to his genes, prohibiting reproductive cloning.

for Rui Nunes, “the technique is not sufficiently robust and sophisticated to give birth to someone without problems,” such as those in sheep, who died in February 2003 with early signs of aging, carcinomas and autoimmune diseases.

But allowed “to deepen the knowledge in order to create again any cell, human tissue or organ.”

“based on this set of technology, we have one pool of cells, tissues and organs vast, “he said.

The fact is also praised for Carolino Monteiro, Professor of Molecular Genetics. Speaking to Lusa, said this was “an important milestone in changing mentalities.”

“There was a profound shock that led to a very interesting international discussion and the discussion also came to Portugal,” he said.

About the fears that accompanied the revelation, the geneticist states that have not materialized copies of dictators or headless men and so little cloning resulted in the breeding of dogs and cats.

expert highlighted the investigations that arose after the creation of Dolly, as the level of stem cells, their existence and use of the applications in terms of the regeneration of tissues and organs.

Dolly “helped to know the disease the very phenomenon of early life and how genes work, “he said.

This sheep was not the first cloned mammal, but had the distinction of being the first born through nuclear transfer of a cell (mammary) adult (a sheep six years).

its name was a tribute to the singer Dolly Parton, known for its prominent chest.

After the team announcement scientists at the Roslin Institute in Scotland, the debate heated and produced to various laws and conventions for the prohibition of human cloning.

at issue were the fear of eugenics (creating perfect humans through handling genetics), the power of scientists and the eternal search for perfection.

to illustrate the theme, there were many images of the Nazi army to remember as he pursued the idea of ​​creating perfect beings, as well as birth comparisons Dolly the atomic bomb.

the unrest reached the US president at the time, Bill Clinton, which banned the use of federal funds for human cloning.

the Vatican has asked for costs these techniques in human and international organizations – such as the World Health Organization (WHO), UNESCO and the European Commission. – requested several studies on the subject

Also in 1997, the Council of Europe adopted a protocol to ban this technique in humans.

It was an explosive mix of concepts and ethical debates. Indifferent to the discussion, the sheep continued to be photographed, studied and condemned to be a star, but the health problems that affect the cloned animals, not slow to make worse their days.

The body Dolly can be seen at the Royal Museum of Scotland in Edinburgh, where it is stuffed.

to Rui Nunes, the birth of Dolly served to open a path to a set of other developments which will be dramatic in the sense positive for humanity.
