stem cells research

Stem cells has the potential to revolutionarise treatment of diseases. It works on the premise of the self-renewal and its capacity to differentiate (transform into) specialized cell types. There're two types: Embryonic (can transform into any cell types) and Adult (specialized). In short, the most powerful stem cells, are the ones that can turn into any cell types. Imagine its usage, for example, cancerous cells destroyed by the mutation. Now plant some new cells into it and voila, healthier ones are now taking place of those diseased ones. Or, in damaged muscles, transplant some of those stem cells and you'll have new ones.

But, the controversy comes from the process of getting the embryonic stem cells. Ethical issues it is, as argued by the exponents, as it is moving towards human cloning which in turn might devalue human beings. Proponents views it as significant medical potential which might provide cure to currently devastating medical conditions.
