According to Stemcells.nih.gov, “ It took nearly 20 years, from the time that growing mouse embryonic stem cells in a lab, to accomplishing similar achievements with human embryonic stem cells” (What are Stem Cells, n.d.). There have also been many barriers that have slowed down the research process. The first, and most detrimental barrier, have been the people that have voted against human embryonic stem cell research. As a result, there were time periods throughout history where there was not any funding going towards stem cell research, and because stem cell trials are costly, there needs to be funding put in place to help achieve results. Another barrier has been the inconsistency of scientists to come across stem cells that become specialized cells. The periods of isolating and maniputlating stem cells can become a very frustrating process, and without precise attention to detail, the results can fail every time. That also presents another barrier, which has been the scientists that have been working on the research. Just like most things in life, not everybody is perfectly suited for one kind of research. The scientists that conduct the experiments have to devote a majority of their work to stem cell research, and without a promising future, many scientists give up. Furthermore, now that the disadvantages have been presented, what are the …show more content…
The unfortunate part of Alzheimer’s disease is that there are no drugs on the market today that can slow down the effects of Alzheimer’s disease, mostly due to the fact that the drugs can not research the parts of the brain that are affected by the disease. Because the brain is literally disintegrating, there is no functioning working part of the brain to receive the drugs. Stem cells could be created to deliver those drugs deep into the brain, and either help slowly down the disease, or help treat the symptoms. Thus, after weighing the pros and cons, it is concluded that the pros outweigh the cons. It is true that stem cell research is a very long and expensive process, but everyday scientists are becoming closer to finding the perfect manipulation. History has proven that good things come to those who
