U.S. and South Korea scientist have created the first early stage embryo clones from cloned cells from two adults. They then extracted tissues from the cloned embryos that matched the DNA of the donors perfectly.
Scientist transferred skin cells from two male donors, ages 35 and 75 to human eggs. The DNA had already been removed before the transfer.
This is the second successful ‘therapeutic cloning’, which was funded by the government of Korea and done in a lab in California. The first cloned embryo reportedly happened in May of last year with baby’s skin cells.
Chief Scientific Officer at Advanced Cell Technology Inc. of Marlborough, Mass, Robert Lanza said, “The proportion of diseases you can treat with (lab-made tissue) increases with age. So if you can’t do this with adult cells, it is of limited value.” Lanza is also the co-author of the study.
The experiment is said to be very controversial, because extracting cells from an embryo diminishes the embryo. Many consider such experimenting to be the same thing as taking a life.
Scientist are also working on the possibility of implanting these embryos in to a womb, but fear it may be unsafe and frowned upon. However, scientist have yet to figure out how to full-fledged human clone. The experimenting has not been successful with animal trials including; monkeys, dogs and rabbits. Much more wasted eggs and tweaking is necessary, before it is figured out.
