10 May 2014. Stem Cell Research Timeline. "Who Discovered: Stem Cells? "Who Discovered Stem Cells?. N.p., n.d.
Because stem cells are unspecialized, they can replace any cell in any part of the body, so as to have a cure for many diseases. There are strong arguments torward both sides of the debate, and stem cell research deserves much more attention from the public than it is getting, for it has a chance to cure many diseases; however, it is inhumane, and there are a few, weak, possible solutions to fix this problem. Stem cells are unspecialized cells that divide into different cell types. (Stem cell - about). For many years, scientists have been researching stem cells to see how they can treat different health issues, such as causes and cures for birth defects, cancer, Alzheimer’s disease, spinal cord injury, heart disease, diabetes, and arthritis (Stem Cells - diseases).
However, most people feel that stem cells are a great alternative to other treatments - until the topic turns to embryonic stem cells, in which a human embryo must be killed in order to harvest these cells. This means that stem cells can be one of two things: 1) stem cell research could be the miracle cure we have been waiting for, or 2) it will it be the cause of World War III. To get a better understanding of the situation is to have knowledge and background to help understand exactly what stem cells are. Stem cells are a type of cell that is found throughout the human body, which can reproduce themselves over long periods of time. These cells have the capability to be specialized in a broad range of specialties such as brain, muscle, and lung cells.
These two main types are adult stem cells and embryonic stem cells. The adult stem cell, according to the National Institutes of Health, is thought to be an undifferentiated cell, found among differentiated cells in a tissue or organ that can renew itself and can differentiate to yield some of all of the major specialized cell types of the tissue or organ. Adult stem cells usually have a specified job, and that job is to repair the tissue where they largely reside. Another type of stem cell is the embryonic stem cell. The embryonic stem cell is taken directly from an embryo, just like the name of the stem cell suggests.
