Snuppy
Being the dog lover I am, i felt like sharing the story of Snuppy with everyone. Let me rephrase that. By everyone I mean the people who have been living in Mars because how can you not know about this doggy doodles who is likely to transform medical research around the world??!!??
Snuppy (the acronym for Seoul National University puppy)has been named the invention of year 2005 by the Time magazine. This is because he’s no ordinary pup. First of all, he’s a clone. He’s also the first dog to have been created through cloning because up until now though other mammals have been cloned (Dolly the sheep, CC the cat and Ralph the Rat) dogs have remained elusive.
Given that my scientific knowledge is limited, I have taken the liberty of copying down the steps of the creation of Snuppy from a magazine article.
1.Donor-dog (in this case a cross breed bitch) eggs are extracted as they are released into the oviduct.
2.The nucleus of the egg is squeezed out through a slit made in the cell’s outer membrane.
3.A biopsy of skin is taken from the ear of a 3-year-old adult male Afghan Hound and skin cells are processed and grown in culture.
4.An entire skin cell is carefully injected into the empty donor egg, using the opening created earlier.
5.An electric charge fuses the egg and its new cargo. The resulting cell is then immersed in a chemical bath and starts to divide and grow.
6.After several days, 10 or more embryos at a time are transferred into a surrogate dog (in this case, a Labrador Retriever),improving the chances that one of them will grow to term.
7.After a normal 61-day pregnancy, Snuppy was born by caesarea section in April 2005
Hwang Woo Suk and his team of researchers at the Seoul National University in South Korea have called this just one of the major steps they are planning to take regarding stem cell research this year. As always, there are heated discussions about the pro’s and cons of such an invention because in dog cloning no improvements can be made to the dog. Only an exact copy can be produced. There is speculation as to whether cloned dogs would end up being used in the laboratories,etc.
Therefore although the experiment has proven to be a success (despite the fact that the other puppy born with Snuppy died at birth) it still will continue to crate controversy as stem cell research always has.
According to the latest news reports, the lead researcher Hwang Woo Suk has resigned from his post after admitting that he used eggs from two female scientists working under him, to be used for one of their human cloning experiments. Due to this unethical action, he has resigned but will continue his work as a researcher.
