Stem cell research lies at the cutting edge of advanced biology. But with the creation of human embryonic stem cells from adult tissues the game may have taken a different turn. The possibility of cloning human babies has become a part of reality.
Science makes the impossible possible. Researchers have employed the technique that led to the creation of Dolly the sheep to create embryonic stem cells. These in turn can be used to make any organs of the body via a complicated process of growth. A US-led team overcame some hurdles which had been faced up until now and created samples of master cells from cloned skin cells. While still in its nascent stages, this discovery could spell the difference between thinking and doing.

Stem cell research has always been a controversial topic since it requires female eggs as well as the creation and destruction of embryos for its basic materials of construction. According to the BBC News, the regeneration and replacement of damaged organs is the basic yield of this procedure. People with damaged hearts or cirrhosis of the liver can gain new organs thanks to stem cell cloning.
Thus diseases that millions of people around the world are currently suffering from may be eliminated effectively via this biological technology. Back in 1996 when Dolly the Sheep was cloned it was already a bygone conclusion that this process was impossible in human beings. But they are not so sure of this today.
In case of Dolly, the cloned egg cell was set multiplying by a mild electric shock. But this had not worked in case of humans. Today the scientists have used caffeine as a solution to the premature development of the cloned embryonic cell. Therapeutic cloning is just a beginning. Who knows where it may lead mankind?
There are those who warn of the dire consequences of this act of “playing God”. They say that by taking over what was Nature’s role in human affairs we are courting disaster on a massive level. Any benefits the process may have are outweighed by the drawbacks in the form of messing with Mother Nature’s sound wisdom.
An example would be a Caesarian Section. While commendable in all its life-saving capabilities, many scientists point out that a normal birth is the method Nature intended for a baby to come out of its mother’s womb. When you force a birth by operating on the mother you automatically traumatize the baby so that he or she will bear the scars for the rest of his or her life. This is a prime example of science overplaying its role in human matters. Stem cell cloning too carries its dangers and so scientists have to be vey careful unless they upset the balance of life.
