Embryonic stem cells amy not be the solution for all ailments.
According to a new research stem cell therapy was used on heart disease patients. It was found that it can make their coronary arteries become narrower.
A disadvantage of most adult stem cells is that they are pre-specialized, for instance, blood stem cells make only blood, and brain stem cells make only brain cells.
A disadvantage of embryonic stem cells is that they are derived from embryos that are not a patient's own and the patient's body may reject them.
Truly, the controversy over human stem cell research will continue to rage furiously. We hope there is some novel scientific innovation in the future, which will have the advantages of stem cells without compromising the right of human life to exist. One should realize that man should control technology and certainly not the other way around.
