He is about to end up run over, his mother saves himAnimal cloning without limits (unfortunately). In fact, a cloned dog was created from a cloned dog. It is not a mistake or a play on words. It really happened. An international team of scientists has recloned the first dog created in the laboratory.
Although the study dates back to 2005, scientists from Seoul National University, Michigan State University and the University of Illinois have just published their article in Scientific Reports.
The team explained that they cloned a dog's clone to learn more about the viability of the cloned animals and to find out whether or not cloning the animals could speed up the aging process or cause previously unknown birth defects.
In 2005, the dog This, un afghan hound male, he became the first to be cloned. Researchers from Seoul National University then inserted his cells into donor eggs and implanted them in the female's uterus.
The result of this innovative plant is Snuppy, a dog who lived a seemingly normal and healthy life on the Seoul National University campus until he died from cancer at the age of 10. The same fate also befell the "original" dog, who died of cancer after living for 12 years.
Tai was raised as a pet in a home and was euthanized at the request of the owner following a diagnosis of hemangiosarcoma at age 12.
"The longevity of both the donor and the cloned dog was close to the average lifespan of Afghan dogs, which is estimated to be 11,9 years" explain the scientists, claiming that the two dogs were now elderly anyway.
When Snuppy was five, however, the researchers took the stem cells again, this time from the clone, and used them to implant 94 embryos in all, resulting in the birth of four re-cloned pups.

A few days after birth, one of the babies died of an unexplained bout of diarrhea. At the time of research, i three surviving puppies they were nine months old and lived in normal, healthy conditions. The research was only published today. The clones of the cloned dog are about 7 years old.
According to the scientists, despite the debates and skepticism about the health of the cloned animals, the clones born without defects showed normal growth. Reproductive characteristics including hormone levels, gonad and gamete formation were also within limits.
“Based on these findings, dog cloning has been used for several purposes, including the conservation of endangered species, the cloning of companion dogs, the production of dog clones with exceptional abilities,” the researchers explain.

At the base of this questionable research is the desire of scientists to learn more and more about the health of clones of clones. For this they are monitoring the three puppies still alive to find out more.
