This is an inspiring in-depth look at what is one of the most promising fields of scientific research currently. I felt that the main purpose of the book was to illustrate to the reader the importance of supporting these scientific ventures as the researchers try to get funding in an increasingly competitive resource pool. With embryonic stem cell research too, there is the added social and political debate between scientists trying to develop treatment options that have the potential to save countless lives, and laypeople who don't understand anything about biology, let alone the potential of stem cell research. Certainly, the medical ethics associated with stem cell research is complex, but hopefully with books like this, the laypeople who feel compelled to lend their voice to the debates can be better informed instead of using only their, frankly, inadequate, religious convictions to form an opinion.
