The biotech industry, which in years past has emphasized molecular biology and biochemistry in its research and development, has more recently placed increased focus on cell, developmental, and system biology techniques. This shift in research has led to greater interest in stem cell research and cell-based therapies.
Major breakthroughs in stem cell research could dominate the biotech revolution. The convergence of the knowledge developed from geonomics and proteonomics of the last decade and the ability to use stem cells as a research platform, could result in new biological pathways, ultimately leading to better understanding of the aging process as well as discovering novel biological targets to cure diseases.
The 2008 US Presidential Republican and Democratic candidates, Senators McCain and Obama, have provided responses on this issue to the non-profit, non-partisan education organization Scientits and Engineers for America (SEA). Here are their respective responses to the following question:
Stem cell research advocates say it may successfully lead to treatments for many chronic diseases and injuries, saving lives, but opponents argue that using embryos as a source for stem cells destroys human life. What is your position on government regulation and funding of stem cell research?
Senator John McCain: "While I support federal funding for embryonic stem cell research, I believe clear lines should be drawn that reflect a refusal to sacrifice moral values and ethical principles for the sake of scientific progress. Moreover, I believe that recent scientific breakthroughs raise the hope that one day this debate will be rendered academic. I also support funding for other research programs, including amniotic fluid and adult stem cell research which hold much scientific promise and do not involve the use of embryos. I oppose the intentional creation of human embryos for research purposes and I voted to ban the practice of “fetal farming,” making it a federal crime for researchers to use cells or fetal tissue from an embryo created for research purposes.
Senator Barack Obama: "Stem cell research holds the promise of improving our lives in at least three ways—by substituting normal cells for damaged cells to treat diabetes, Parkinson’s disease, spinal cord injury, heart failure and other disorders; by providing scientists with safe and convenient models of disease for drug development; and by helping to understand fundamental aspects of normal development and cell dysfunction.
For these reasons, I strongly support expanding research on stem cells. I believe that the restrictions that President Bush has placed on funding of human embryonic stem cell research have handcuffed our scientists and hindered our ability to compete with other nations. As president, I will lift the current administration’s ban on federal funding of research on embryonic stem cell lines created after August 9, 2001 through executive order, and I will ensure that all research on stem cells is conducted ethically and with rigorous oversight. I recognize that some people object to government support of research that requires cells to be harvested from human embryos. However, hundreds of thousands of embryos stored in the U.S. in in-vitro fertilization clinics will not be used for reproductive purposes, and will eventually be destroyed. I believe that it is ethical to use these extra embryos for research that could save lives when they are freely donated for that express purpose. I am also aware that there have been suggestions that human stem cells of various types, derived from sources other than embryos, make the use of embryonic stem cells unnecessary. I don’t agree. While adult stem cells, such as those harvested from blood or bone marrow, are already used for treatment of some diseases, they do not have the versatility of embryonic stem cells and cannot replace them. Recent discoveries indicate that adult skin cells can be reprogrammed to behave like stem cells; these are exciting findings that might in the future lead to an alternate source of highly versatile stem cells. However, embryonic stem cells remain the “gold standard,” and studies of all types of stem cells should continue in parallel for the foreseeable future. Rather than restrict the funding of such research, I favor responsible oversight of it, in accord with recent reports from the National Research Council. Recommendations from the NRC reports are already being followed by institutions that conduct human embryonic stem cell research with funds from a variety of sources. An expanded, federally-supported stem cell research program will encourage talented U.S. scientists to engage in this important new field, will allow more effective oversight, and will signal to other countries our commitment to compete in this exciting area of medical research."
