Introduction

Contents Pg. 2 Introduction Pg. 3 Stem Cells - What are they? Pg. 5 Diabetes Pg. 7 Stem Cells and Damaged Hearts Pg. 9 The Nervous System Pg. 10 Stem Cell Research Objections Pg. 12 Conclusion References Information I had decided to display the references of each page at the bottom of that page; this is an alternative to having a references page at the end of this report. The date after each link is the date of which I used the source from that site. The reliability score is my personal judgement on how reliable the information is. Introduction "Stem cells are like little kids who, when they grow up, can enter a variety of professions" - Dr. Marc Hendrick 1 2 Stem Cells - What are they? Stem cells in animals are able to split and differentiate without limit into other types of cells such as muscle cells, brain cells and skin cells. So what does this mean? Stem cells can act as a repair system for the body - replenishing other cells. One way in which stem cells can be categorised is by potency; the different classes for stem cells are: Pluripolent stem cells are secluded from human embryos that are more than a few days old. Scientists are able to use the cells in this embryo to create stem cell "lines". 3 3 Adult Stem Cells We have known about adult stem cells for 30 years 4. ...read more.

This may seem intriguing, but unfortunately there is still no evidence that there are true stem cells in the heart which can reproduce and differentiate6. The Nervous System Researchers are trying to solve the nervous system disorder - Parkinson's Disease by regenerating damaged tissue7. Even though Parkinson's is of course difficult to reverse, it is a moderately easy target because a regenerative therapy need only replace one particular cell type in one part of the brain. However therapies for other disorders come across much bigger problems. Complete restoration after stern spinal cord injury is most dubitably far in the future. Many cell types are damaged and destroyed in injuries such as these, including neurons, which are cells that carry messages to and from the brain and the rest of the body. Getting neurons to develop past an injury site and connect suitably with their targets is extremely difficult7. Spinal cord injury patients would however benefit significantly from an still limited restoration of lost functions-gaining partial use of a limb (compared to none) or being unchained from pain. Such limited restoration is possibly a more realistic and achievable goal. Stem Cell Research Objections "We should not as a society grow life to destroy it, and that's exactly what's taking place..." - George Bush8 This report so far has been rather biased with information regarding the potentiality of stem cell research. However I will now explain some of the negative effects with stem cell research; as explained in the introduction, gathering embryonic stem cells destroy the human embryo. ...read more.

Conclusion

"Is research on embryonic stem cells worth the consequences?" -I believe research should be done with strict rules; aborted embryos that will be disposed of should be benefited from, stem cells from these embryos are what should be used. "Are the clashes with bad science and religion a legitimate reason to abort research?" -No, being an agnostic person, I personally believe that research should go forward despite what religion and pro-lifers say. Overall, my opinion is that the positive effects outweigh the negative, and I yet to come across enough valid evidence that supports ideas such as embryonic stem cells may cause cancer, and that they are unnecessary due to adult stem cells. 1 http://en.wikipedia.org/wiki/Stem_cells - June 8th 2006 (Reliability Score - 7/10) 2 http://www.guardian.co.uk/usa/story/0,12271,1491535,00.html - July 1st 2006 (Reliability Score - 8/10) 3 http://stemcells.nih.gov/StemCells/Templates/StemCellContentPage.aspx?NRMODE=Published&NRORIGINALURL=%2finfo%2ffaqs%2easp&NRNODEGUID=%7bA604DCCE-2E5F-4395-8954-FCE1C05BECED%7d&NRCACHEHINT=NoModifyGuest#classes - June 21st 2006 (Reliability Score - 9/10) 4 http://www.lifeissues.net/writers/edi/edi_06stemcelldebate.html -June 15th 2006 - Reliability Score (8/10) 5 http://stemcells.nih.gov/info/scireport/chapter7.asp - 1st July 2006 (Reliability Score 9/10) 6 http://stemcells.nih.gov/info/scireport/chapter9.asp - June 29th 2006 (Reliability Score - 9/10) 7 http://stemcells.nih.gov/info/scireport/chapter8.asp - July 1st 2006 (Reliability Score - 9/10) 8 http://archives.cnn.com/2001/HEALTH/11/26/human.cloning/ - 5th July (Reliability Score - 9.5/10) 9 http://www.meta-library.net/stemtp/index-body.html - 4th July 2006 (Reliability Score - 8/10) 10 http://stemcell.uci.edu/facts/funding.cfm - 17th June 2006 (Reliability Score - 9/10) 11 http://news.bbc.co.uk/1/hi/health/3583439.stm - 12th June 2006 (Reliability Score - 9/10) 12 http://news.bbc.co.uk/1/hi/health/4555023.stm - 26th June 2006 (Reliability Score - 9/10) 13 http://www.lifeissues.net/writers/edi/edi_06stemcelldebate.html - June 7th 2006 (Reliability Score - 7.5/10) 14 http://www.pollingreport.com/science.htm - 19th June 2006 (Reliability Score - 8/10) ?? ?? ?? ??

    This explains why living things have so many similarities. These simple things changed over time to produce all kinds of living things on earth today, the changes also produced many species that are now extinct. This process of change is called evolution, and its still happening today.? ?What evidence is there for evolution?? ?Fossils are made from the bodies of living things.

  1. Should Cloning Human Beings Be Legallised In the United Kingdom?

    However, there are many pieces of evidence to substantiate the fact that cloning is a completely natural process. Firstly, some organisms in nature only reproduce using cloning, such as yeast and bacteria. In nature sexual reproduction is the only way to improve the genetic stock of a species.

  2. What is population genetics and how is it put to practical use?

    it to do so is approximately 4N with large error bars either side. From this model you can see that the size of the population will have an effect on how much genetic drift will affect allele frequencies. This is well illustrated with this graph (Li 1998); This clearly illustrates
