Stem cell research has caused a big ethical debate across the nation. The stem cell lines developed for stem cell research are established from embryos after fertilization. An embryo is then divided into individual cells to create a stem cell line. From the embryo, one cell is placed in a dish and nourished with substances that stimulate the cell to divide, then the resulting line will then continue to divide in a managed environment and if taken care of properly (Creating Stem Cells For Research). The stem cells created can then be used to replace damaged cells. The United States Congress should support stem cell research for helping cure diseases but not for the experimentation of human cloning. Stem cells create many amazing …show more content…

Recent research has found populations of stem cells in many tissues such as the liver, lungs, brain, and even teeth. Scientists are also predicting that they will sooner or later find stem cells in almost every tissue, giving scientists the opportunity of repairing a person's tissue with their own cells (Brownlee). It is possible, that one day, stem cells will not only make other cells but also organize these cells into an organ (Stem Cells to the Rescue?). For scientists interested in using stem cells to take the place of damaged cells, it is crucial to coax the stem cells to differentiate into the right tissue type before they are placed where they are needed (Brownlee). Douglas Losordo from Tufts University in Boston and his colleagues have done research that shows that stem cells from bone marrow circulating in the blood, could transform into the cells that make up blood vessels. New blood vessels could provide different paths for blood flow in patients with clogged arteries (Brownlee). Future experiments will look into the possibility that stem cells can transform into other types of cells, such as brain cells. In the long term, stem cells that could help repair human tissues is an available possibility (Testing science). Although stem cell research brings many positives to the table, it also has a lot of negative prospects. The most well known and controversial part of stem cell research is the destruction of a human embryo. This factor
