Embryo's Gift To Mankind

New stem cell research might lead to more cloning experiments especially after the breakthrough with Dolly the sheep. Also stem cell research is leading to curing many diseases. Many experiments they do on animals have showed superb results that will soon be taken to the human stage to see if those experiments show good results also. They have been doing experiments on many animals but sheep and rats show the best results because they are cloning sheep and curing many diseases that the rats have. They are also finding many other sources to find stem cells. The best to use are embryonic stem cells but they are finding ways too get stem cells out of adult humans/animals.
