Human stem cell research is a major hot button topic that divides the conservative and scientific communities. Religious conservatives see it as tampering with nature and even playing God. Scientists, on the other hand, see the potential to treat many of the life threatening diseases of our times - from heart disease and diabetes to Parkinson's and Alzheimer's.
There's no question that there's been a lot of hype surrounding both sides, so it's refreshing that in The Stem Cell Divide provides a non-biased look at the science and politics surrounding this controversial topic.
The book is divided into 3 parts: Discovery of the Stem Cell's Unique Abilities, The Race to Harness the Power of Life, and Stem Cell Cures and Curses. There are two appendices: one describing how human cells are cultured and the other describing California's legislation concerning the funding of stem cell research. The book also has a fairly extensive glossary.
The first part of the book is concerned with stem cell basics. This section is designed to get novices up to speed with the history and process of stem cell research. Bellomo clearly explains why embryonic stem cells have advantages over adult stem cells, the scientific research up to this point, and our main sources for embryonic stem cells - namely stem cell cultures maintained by Dr. James Thomson of the University of Wisconsin and potentially, the thousands of unused embryos that are discarded at in vitro fertilization (IVF) clinics.
The second part of the book discusses the opposition President Bush has faced from his own party by his decision to veto any bill that allowed federal funding of embryonic stem cell research. Bellomo makes it extremely clear that the issue at hand is not whether embryonic stem cell research should be legal - it already is allowed, remains unrestricted, and is perfectly legal - but whether it should be federally funded.
On August 9, 2001, Bush announced that federal funding would only be allowed for researchers who experimented on the 60 or so existing embryonic stem cell lines. Determined to keep biotechs within the state, California responded with Proposition 71, legislature that essentially made conducting stem cell research a state constitutional right and allowed $3 billion in funds to be given over 10 years to stem cell research facilities, and specifically, embryonic stem cell research. That sparked a number of other states to also propose legislation to fund embryonic stem cell research.
At the federal level, President Bush has faced opposition in Congress. In May 2005, the Republican-controlled House passed a bill allowing federal funds to be used for embryonic stem cell research. Even staunch supporter, Dr. Bill Frist, broke from the Bush camp to support the legislation, saying:
"We should federally fund research only on embryonic stem cells derived from blastocysts left over from fertility therapy, which will not be implanted or adopted but instead are otherwise destined by the parents with absolute certainty to be discarded and destroyed."
Bellomo also addresses the rise and fall of Dr. Hwang Woo Suk, the South Korean researcher who claimed incredible advances in stem cell research and became somewhat of a celebrity in his home country. His promising career came to a crashing halt when it was made public that he had fabricated much of his results and had breached ethical guidelines when he paid women to donate their eggs for embryonic research. Scientists are still trying to decipher what, if any, part of his research is valid and what was fabricated.
Finally, in the third part of the book, Bellomo discusses the promises of therapeutic cloning - when embryonic stem cells are removed from the blastocyst, harvested in a culture dish and then injected with the nucleus from a donor cell so that the cell makes copies of the donor genetic material. Therapeutic cloning offers great potential to generate replacement tissues and organs for illnesses and injuries that currently have no cure and will greatly reduce the rejection rate for patients that need organ transplants. It is thought that if organs and tissues are grown from a patient's own cells, their body will be much less likely to reject the transplant than if that organ was donated by someone else.
Bellomo doesn't shy away from alternatives to embryonic stem cell research, covering briefly the pros and cons of using adult stem cells and germ cells, before tackling some of the key arguments for both sides.
Ethically, conservatives argue that embryonic stem cells are still the foundations of human life and therefore they have a right to life. As James Sherley of MIT says,
"A human life begins when a diploid complement of human DNA is initiated to begin human development. Therefore, a life can be initiated by the fusion of sperm and egg or by the introduction of a diploid nucleus into an enucleated egg (ie cloning)"
James Thomson argues from a different perspective.
"The bottom line is that there are 400,000 frozen embryos in the United States, and a large percentage of those are going to be thrown out. Regardless of what you think the moral status of those embryos is, it makes sense to me that it's a better moral decision to use them to help people than to just throw them out. It's a very complex issue, but to me it boils down to that one thing."
Advancements in cellular research may eventually make therapeutic cloning more acceptable as scientists learn to remove the inner cell mass of a blastocyst without destroying the embryo or as research into how diseases develop helps find cures that don't require such practices. The final chapter offers predictions of where Bellomo sees the progress several years into the future.
While the byline of the book "The facts, the fiction, and the fear driving the greatest scientific, political, and religious debate of our time" suggests that it will tackle the ethical, religious, and political debate on stem cell research, the book only briefly tackles the ethical arguments for each side while focusing on the scientific process, experiments, and funding legislation.
The writing style is accessible and explains the science in clear terms with diagrams. This is a great, matter-of-fact overview of stem cell research that allows its readers to draw their own conclusions based on the facts presented. It will be useful to those looking for a comprehensive introduction to the subject as well as those looking to catch up with the latest research.

There has been much recent debate about the merits, dangers, and nature of stem cell research. Some see in it the answer to every debilitating disease known to man, while others see it as a step away from human cloning. While the battle has raged, research is moving ahead, and California has already passed a measure that will give $3 billion in support to stem cell research. But as politics, religion, and the media weigh in on this complex issue, more and more of the scientific reality of stem cell research is getting lost. In the search for the truth about stem cell science, the author has interviewed the scientists whose cutting-edge research is at the very heart of this hot-button issue. The book explains what they have accomplished so far, what they're currently doing, and what they see on the horizon. The Stem Cell Divide does not take sides, and the author debunks the distortions and exaggerations that come from every camp. This book does not tell readers what to think, but gives them the facts necessary to form their own opinions about one of the most divisive, complex, and potentially life-changing developments in history.
