A huge controversy touches upon stem cell research because of the way embryos are created, used and destructed for study purposes alone. The main interest in stem cell research comes from the possibility to develop treatments and cures for the irrecoverable diseases that plague humanity such as cancer, Alzheimer’s, diabetes, Parkinson’s, heart attacks and so on. Yet, lots of pro-life supporters who argue 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. Even if they have a lower biological potential, adult stem cells for instance represent a great study material and a constant replacement for embryonic stem cells samples.
Unlike adult stem cells, embryonic stem groups can develop into absolutely any type of cells specific to the body. 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 very often they are rejected by the immune system. 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.
The truth is that stem cell research has more to do before real treatments can be performed in full safety and knowledge of the outcome. The only kind 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 tries to find alternative sources for cells, 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, it was discovered that the amniotic fluid surrounding the fetus in the uterus contains stem cells that can differentiate and develop into bones, blood vessels, muscles, nerves and organs. This new resource for tissues could enhance the possibility to develop methods to repair injured or malfunctioning organs.
