Stem Cell Therapy
Due to confusion and general lack of knowledge stem cell research is sometimes wrongly thought of as unethical. Stem cells are model cells found all through the body that have the ability to possess concentrated roles. These cells are grown to imitate blood, bone, brain, or skin cells among others (Heled, 2008). There are different kinds of stem cells deriving from different areas that produce different results. Embryonic or fetal stem cells are believed to be the most influential and controversial in stem cell research. According to the American Journal of Health Education, “(embryonic stem cells) can differentiate into almost any type of cell that makes up the body” (2008). They originate from four different places: existing stem cell lines, aborted or miscarried fetuses, discarded embryos from fertilization, or cloned embryos. Adult stem cells are harder to manipulate; however, they do offer great insight into stem cell research. Adult stem cells can be found in different parts of the brain and bone marrow (Eve, Marty, McDermott, Klasko, Sanberg, 2008). Because of federal funding there is more adaptability with adult stem cells making them more available. Placental or umbilical cord blood stem cells contain a smaller level of stem cells, but have resulted to be beneficial in the treatment of different disorders. Current research of these cells has brought about encouraging possibilities, but as with all new ideas it does need to be explored more. Stem cell research and the cloning of humans and animals is not the same thing. The cloning of humans to full term is banned more or less across the globe. In some cases short term cloning was performed to allow for the creation and mining of stem cells; however, following the tests the cloned embryos were terminated (Eve, Marty, McDermott, Klasko, Sanberg, 2008). World wide a handful of animals have been cloned, but were inundated with problems resulting in tighter restrictions on human stem cell research. Recent research on cloned animals implies that the duplicated cells do not restart their lifespan, insuring an earlier death. Stem cells are thought to be the foremost uncultivated source for deterrence and healing of many diseases (see Chart 1). The process has shown new hope for many horrible degenerative diseases. Mice reproduced to show signs of Sandhoff disease, an adolescent disorder, implanted with stem cells revealed progress. Depleted levels of the Hexosaminidase trigger the disease. It was found that by implanting the stem cells it replenished the low levels rebuilding the dwindling amount. Additionally, with the help of stem cells scientists are initiating modern methods to regenerate brain cells used to treat Parkinson’s disease. By replacing defective cells with...
