Stem Cells
Over the past decade, genetic engineering has advanced into one of the most important branches of science. Thousands of hours of research have been spent studying and manipulating the DNA of cells to benefit human life. A few years ago, the main topic of discussion about genetics was cloning. However, the new topic surfacing is the use of stem cells. A stem cell is a cell that is not programmed to perform a specific duty. It is a general cell that matures before it is classified and becomes a specialized cell. Since stem cells are general they can easily be manipulated into any kind of cell that a scientist wants it to be. This means that scientists could create tissues to replace damaged tissue in a person. People with ailments such as heart disease could receive new cardiac tissue that is healthy. Stem cells could also be used to help diseases. A person with diabetes might be able to create their own insulin with the placement of new pancreatic tissue. These are just
The use of stem cells is an exciting and yet bothersome idea. It is like an idea from a science fiction movie that has crossed into reality. With the advancement of stem cells human life may be significantly prolonged. However, since the most promising results lie with embryonic stem cells, the question of whether the taking of a human life is involved. People must weigh the results against the consequences and decide if continuing with stem cell development is ethically and morally acceptable. two of the potential abilities of stem cells. However, obtaining these stem cells has become a task that has stirred up questions about the necessity of them. There are two major types of stem cells: embryonic and adult. Each type of stem cell has positive and negative aspects to their use. Another kind of stem cells is adult stem cells. They are extracted from tissues in the adult body. They are used to replenish the dying cells in organs, and are essential to the maintenance of the human body. Stem cells have been found
