Explore an Issue – Take a Stand: the Future of Stem Cell
Research
Statement: Governments should redirect some funding from organ transplant
research to autologous (i.e., originating from the same individual)
stem cell research
- Investigate this rapidly changing field of research. Search
for information in newspapers, periodicals, CD-ROMs, and on the Internet.
Prepare a list of points and counterpoints. You might want
to consider the following questions:
i. Researchers are working on ways to use mature cells as
a source for stem cells as well. How will this change the prospects
for successful treatment?
ii. Companies have applied for patents on specific stem cells and
techniques used to culture stem cells and induce differentiation.
These companies will own a medical procedure and collect huge royalties.
Should this be allowed?
iii. Why do many people object to stem cell research?
iv. Why are governments regulating this field of research?
