Stem Cells - future prospects Scientists at Advanced Cell Technology in Worcester, Massachusetts, took a skin from Cow A, cloned it (by injecting the nucleus into a cow egg whose nucleus had been removed), then implanted the embryo in the uterus of Cow B. That embryo clone grew into a fetus, which, had it been born, would have been Cow C. But it was not born. The fetus was removed from the uterus and harvested for its tissues. These tissues from the clone were then put back into the original Cow A. It worked !!. These cells from the clone were not rejected by Cow A ! These cells organized themselves into functioning tissue such as kidney. It an amazing success. By this technology the advocates of cloning research are promising great possibilities for incurable diseases like Alzheimer's disease, Parkinson's disease, Spinal-cord injuries and innumerable conditions which stand incurable today. All this is causing a big concern among those who consider this as "Manipulating Humanity". We do not know where all this would lead us to. That day may not be far when humans too would be treated the same way as the Cows and Dogs.
