The Pros And Cons Of Stem Cell Research
There is a huge morality question concerning the use of human embryos for stem cell research that claims their life. On the other hand, stem cell research gives hopes to the medical world about the possibility to cure diseases like Alzheimer, Parkinson's, heart attacks, diabetes, strokes and many others. Yet, lots of pro-life supporters who protest against stem cell research don't really know that there are many processes and lab tests that work with stem cells without causing any harm to human embryos. Adult stem cells for instance represent a good biological material to work on, although with a lower potential then embryonic stem cells.
There are many limitations related to the specialization potential of adult stem cells, particularly since embryonic cells have an unlimited variants of differentiation. Moreover, stem cell research has proved the fact that stem cells collected from embryos are more valuable in the treatment of nervous disease. There are bad bits to embryonic stem cells as well because the immune system could reject the transplant. Such an issue ought to be known to parents who store umbilical cord stem cells, so that they may not be given false information that such samples can solve any future disease their child could be fighting against.
Lots of mysteries remain unsolved for the moment, and stem cell research needs to progress a bit further before coming up with new and viable treatments. The only type of stem cell transplantation that is no longer an issue or secret for the medical world is bone marrow transplantation, that has been practiced for almost fifty years now with great success. Otherwise, the rest of the cures available on the basis of stem cells are usually experimental and pretty expensive. For the moment, stem cell research needs to come up with other collection sources other than embryos.
A great success was reputed by stem cell research in 2007 when three stem cell lines were created at the Advanced Cell Technology Institute without causing any harm to parenting embryos. Such significant achievements of stem cell research have been unparalleled so far in the history of medicine. In the same year, 2007, scientists announced that the amniotic fluid surrounding the fetus in the womb contains stem cells that can differentiate and develop into bones, blood vessels, muscles, nerves and organs. This new tissue resource could increase the chances of developing ways to repair malfunctioning or injured organs.
