Human cloning: the future?
Is the human cloning the future of the world we live in? The first human clone was not born yet, but the techniques that will be used for human cloning advance rapidly. Molecular biology and reproductive genetics are two of the most important parts that are strongly connected with human cloning. Methods for cloning animals were discovered a decade ago. Neither primate was cloned with these technologies. This doesn’t mean that it’s not possible; specialists have not tried this yet. However, there are many chances for human cloning to present great challenges.
When it comes about mammal cloning, there are used adult skin cells that are reprogrammed to primitive states. In this case, primitive refers to an early stage of the cell’s development so it’s not about a prehistoric condition. So, the adult skin cells are transformed into primitive pluripotent cells. These cells have the ability to transform into any type of cells. This means that they can turn into muscle, gastrointestinal, blood and nerve cells. The adult cells that are used in the process of mammal cloning are different because they possess a specific structure that has specific tasks. By reprogramming them to pluripotent cells specialists have the ability to use the cell’s SNA as main material to fertilize an egg that has the DNA removed. The process through which DNA in injected in another cell is called somatic cell nuclear transfer and it’s also known as SCNT. This process involves modern technology. This technology is so brilliant that it can work to the extent that a clone is being created. However, this technology is used in order to replace physiological processes that were used for hundreds of years. In most cases, these substitutes that come from the modern technology usually distort with critical events or they introduce new elements that can be destructive to the clone. This argument is similar to those that don’t agree with the fact of introducing genetically modified organisms in our environment. This means that trying to do other things than Mother Nature, is a very bad idea. Even is human cloning would surely change science and also this world, the danger involves causing some alterations to the human genome. To be more specific I will offer you a clear example. The process through which adult skin cells are reprogrammed to their primate states automatically involves regulatory proteins and genes that are causing cancer. That’s because pluripotent cells are unregulated cells, their main characteristic being represented by the fact that they have the ability to self-renew. Cancer sells are almost the same thing with pluripotent cells and this means that they also have the same characteristics.
However, human cloning has also some important benefits. For example, cardiac disease is these days a fatal disease that affects people from the entire world. Specialists believe that they are able to rebuild a diseased heart by simply cloning healthy heart cells. Human cloning can also be the secret of eternal youth. This is a topic that will never die because it develops many controversies. There are people who agree with human cloning and there are people who don’t want to hear about it.
