Another interesting and possibly the most beneficial potential
of stem cells is that stem cells can help someone with paralysis walk again.
There have been tests done on rats and the rats have been able to walk again
after stem cells were made into new neural cells. This is amazing and will give
many paralyzed individuals a chance to live again and do things that they
otherwise never have been able to do.
These
are interesting polls that I found on Gallup polls. One measures by political
party, the acceptance of embryonic stem cells which for each party was over
50%. The other shows individuals
personal point of views of stem cells. Again there is an overwhelming amount of
support for stem cells. This shows that because of the great promise of stem
cells the acceptance has improved.

In finding support
articles for stem cells the website Nature and Science were
very helpful. If you are interested in stem cells or even science in
general I would check these two websites out!

One avenue of research
that I have not looked into much is the claim that hES cells can cure
blindness. This interests me because I have very bad vision and have
been interested in alternative ways of improving vision. A study done
in 2012 using hES cells improved two blind woman's vision
exponentially even in lower doses. This is not the only reason why this study
is so important.The study is also important because this is the first time when
hES cells were successfully implanted in a human. This holds great
promise for the future by not only helping repair vision but research using hES
cells in general.
On March 9, 2009 former
President Bush's policy on stem cells was repealed by President Obama. He then
put in place a policy that benefits scientists that do stem cell research and
that he will open up more federal funding to new embryonic stem cell lines.
When I first found this out I was ecstatic because it gives
scientists more funding and more availability of stem cells.
This will progress research much farther than it would have if the funding
was still restricted and may lead to a cure of a major
disease, plaguing millions.
This is a picture of 2 brains, one normal and one with Parkinson's. This image shows that in the brain with Parkinson's there is much less activity because less dopamine is being made. Human embryonic stem cells have been shown to improve dopamine production by adding new neurons into the brain. This would stop and even reverse the effects of Parkinson's.
1.2 million
individuals suffer from heart attacks each year and many of these are fatal
and unfortunately those who survive will have scar tissue. Scar
tissue does not pump blood as efficiently which leads to an
increased risk of having another heart attack. A heart attack sufferer
does not have to be plagued for the rest of their lives. A study
conducted at Cedar- Sinai showed that scar tissue in humans shrank between
30-47% using stem cells. This study amazed me because heart attacks are so
common and if the heart efficiency can be improved this will
lower the risk of another heart attack.
This link contains
information about the difference between adult and embryonic stem
cells. It also has other great information such as potential of the cells and
an informational section about stem cells in general.

This is an
interesting video if you are not familiar with embryonic stem cells and how
they come about. There is a 30 second clip and there is also an 8 minute video
that will widely broaden your knowledge stem cells in general and will
challenge you because it is a bit more difficult to understand.
Suzanne Holland, Laurie Zoloth, and Karen Lebacqz edited the book The Human Embryonic Stem Cell Debate: Science, Ethics, and Public Policy. The novel contains several articles, some written by the editors and some by others, on the topics of stem cells. I would recommend this book to anyone that is interested in stem cells not so much on the scientific side but on the views of others on the topic of stem cells. This book offers views from a feminist, someone of Jewish faith, someone of the Roman Catholic faith, someone of the Secular faith and someone of the Christian faith. Overall the book was a great read and provided me with a great deal of knowledge related to many views on stem cells.
