Wow, have you heard the news about Dolly the sheep that was cloned, amazing thing isn't it? No I did not find out about it and I am sure most of you heard about it back in 1996 as it was all over the news back then.
However, I asked the question simple to jog your memories for a lead up to my other question. Do you know that since Dolly was cloned that a number of others animals were cloned as well?
Didn't know that did you? As a matter of fact including Dolly there were plenty more animals cloned and those are the ones that we have been told about.
Just to name a few here from the biggest animal ever cloned that we know about is a horse or depending on how you look at them there were also cows.
Going down in size we get pigs and going down even further we get cat and even further down we come to rats and then mice. Notice that I used that I used the plural tense for all these animals. However, in that great age of technology the scientists of the day could not cloned a dog.
The problem at the time was, getting a bit technical here, the process used for maturing the ovum of the dog in an environment that was artificial to the body of a dog.
However, the procedure was soon overcome by a scientist and professor of the national University of Seoul, a Mr Woo-Suk Hwang, he successfully used tissues from the ear of and Afgan Hound who was three years old at the time.
He was over one thousand implantation on surrogate mothers, (dogs) of the embryos. As a result out of the thousand or so only three of them took and resulted in pregnancies.
Out of the three the first was a miscarriage, a second was born but died three weeks later and the third was carried by a Labrador Retriever.
You might be wandering at this point how is something like that even possible or how would someone go about doing something like that or even where would even start?
Well I think that I might be able to shed some light on the process and no I have not cloned an animal, but I had researched the topic not to long ago while at College.
As far as a I remember the process was very technical and complicated to me at that time, I am not even sure if I understand it myself.
However, although I might not understand the technical aspects of it I do understand the process enough to explain it to you here briefly.
The eggs of a female dog is only be fertilized for a certain length of time, which is at a certain phase during the time of the Estrous cycle and can only be harvested during the three weeks period.
Then the eggs are taken from the oviduct because of the intricate nature of removing the eggs. After the eggs have been taken out this is where they take out the nucleus from the eggs and replace it with the cell from the dog's ear as mentioned above.
Then they use a chemical reaction to bound them together, that is the egg and the cell from the dog's ear. After this was successfully done the eggs would be placed in the female dogs that will become surrogates.
This particular process took three years to complete and the result was that the female Labrador gave birth to the first ever cloned dog who was named Snuppy.
The cloning process has generated a lot on interest even more so than the result of the process, which was the cloned dog Snuppy.
In 2005 Time Magazine ran article in which Snuppy was named the most amazing invention of the year, this was no doubt an implication to human cloning.
The scientist behind the cloning of Snuppy Dolly is against the idea and have stated that they should be banned on human cloning.
The whole idea of cloning was rejected by the Kennel club sighting the well being of dogs species cannot be maintained if people are replicating them.
