The many controversies revolving around stem cells has encouraged many people to focus on the potential drawbacks instead of the obvious benefits. Apparently, stem cells have proven to be quite beneficial in testing new drugs and curing serious illnesses. Some studies have proven that it can also cure several types of cancers.
Despite all this, its application has resulted in raging debates for some years. Initially, it was illegal and was only accepted by a few after a realization that it could be a solution to several complications including illnesses that had no cure. One question is, where do all these controversies come from? Are there other possible stem cell research application in future?
You may wonder why some people are against a medication that has proven to be a cure for several illnesses that were assumed to be untreatable before.
The main issue here is abortion. According to those who are opposing stem cell research, obtaining stem cells from a living embryo is indifferent to abortion simply because the embryo will be useless after testing. On the other hand, the proposers claim that incorporating stem cell therapy in the medical industry is promising to both the patients as well as families around the globe. This is because of stem cell therapy, unlike other previous ineffective treatments, has proven to work for several incurable illnesses such as Parkinson’s, Alzheimer’s as well as other cancer types.
What are stem cells and how do they help cure diseases?
Stem cells exist in human bodies. Their role is to maintain as well as repair the cells of the tissues. To do this, they only divide and repair when they are required to, for example when there is an injury to the tissues. They can also be found in other sources such as skeletal cells, bone marrow, blood vessels, teeth and bone marrow.
It was not until recently when the scientists figured out a way to reprogram stem cells that can treat several complications and diseases. This has made it possible to use the stem cells to cure several illnesses that include cancer, blindness, and many others. Realization of this has encouraged even the pharmaceutical firms and consultancy to agree with the claims made by the scientists behind it.
Despite this, there are still some steps needed to improve the usefulness of the research. Stem cells can also be extracted from the organs, or the living blood of adults eliminating the issue of abortion hence encourage the research to continue. The drawback in using this method is that scientists claim that they are not as useful as the living embryos.
Even with the raging debates, it is clear that stem cell has revolutionized medicine. They have been used in testing new drugs that include tumor drugs; they also work best in regenerating damaged cells of the tissue and the best part, they can completely restore damaged tissue. The point is, stem cell research is promising to health sectors, but until it is fully accepted, there is a lot to be discovered.
