Using stem cells?Watch
Can anybody with knowledge in this area help me out?

Of course, there are many types of stem cells and the most controversial are embryonic stem cells because these needs to be taken from a fertilised human egg (although I believe some can be harvested from the placenta). In this case, a fertilised human egg may be sacrifised and some people have an issue with this. A lot of religious people think this is playing god.
Adult stem cells can be taken from consenting adults and this issue is less controversial. However, these cells are not as good as embryonic ones as they cannot differentiate into any cell type.
