Stem Cell



In the medical field today, there are so many different disease, or abnormalities that have yet to be cured. There has come one solution/cure to some cases, which are stem cells. Stem cells are cells that are found in most multi cellular organisms. So what is so special about these cells, “the ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types.” So in cases where an individual has dead cells this would really be helpful. There are two different types of stem cells you have embryonic and adult. The embryonic stem cells are the ones that are most wanted, because they can differentiate into all of the specialized embryonic tissue. Today some stem cell therapies can be seen, such as bone marrow transplant to treat leukemia, but it is still under research for treating other human diseases. Medical professionals hope to be able to use this to treat other disease such as, cancer, Parkinson's disease, spinal cord injuries, Amyotrophic lateral sclerosis, multiple sclerosis, and muscle damage, but the human ethical issues always come in to play. Right now united states is one of the only countries not going through with stem cell implants, In majority of places in Europe it has become really successful, and the reason why it has yet to be passed in America is because it is seen as un ethical. The process of stem cell research is, destruction of a human embryo and/or therapeutic cloning. So pretty much you would have to kill an unborn human being to get some stem cell to research. Although, they have been working on other ways and have come up with a way of getting around he embryonic destruction. To take adult stem cells and manipulate them to create embryonic stem cells. So, we will just have to wait and see, could we be getting closer to curing the incurable cancer?
