The Pros And Cons Of Stem Cell Research

Stem cells have the latent ability to cure any disease. Commonly, a disease, known as macular degeneration, develops in the eyes of the elderly. Macular degeneration takes place when damage to the inner retina, known as the macula, occurs. Mark Humayun, Professor of ophthalmology and biomedical engineering at the University of California, theorizes that using stem cells to regenerate portions of the retinal pigment epithelial cells to treat macular degeneration (Can Stem Cells Research Lead to Macular Degeneration Treatment?). "Stem cell therapies are not new. But when scientists learned how to remove stem cells from human embryos, both excitement and controversy ensued" (The Stem Cell Debate: Is It Over?). Excitement over the array of new possibilities, and controversy over the moral and ethic implications, of stem cell research. Quite possibly, stem cells could bring human life invulnerability. Thus, the requisition of stem cell research is imperative to elongating the existence of human life. Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. In addition, in many tissues, they serve as an internal repair system. When a stem cell divides, each new cell has the capability of either remaining a stem cell, or becoming another type of cell with a more specialized function, such as muscle cells, blood cells, or brain cells (Stem Cell Basics). "Stem cells have an interesting history that has been somewhat tainted with debate and controversy" (Murnaghan). In 1998, Thompson, from the University of Wisconsin, isolated cells from the inner cell mass of early embryos and developed the first embryonic stem cell lines. During that same year, Japanese and American research teams anno... ... middle of paper ... ..." (What are Stem Cells?). Often, "human cells are inserted into animals(like mice or rats) and are allowed to develop. This creates the opportunity for researchers to see what happens when stem cells are implanted. Many people, however, object to the creation of an organism that is 'part human'" (What are Stem Cells?). Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Common sources of stem cells are embryonic stem cells and adult stem cells. Uncommon sources of stem cells are fetal stem cells and induced stem cells. If research goes accordingly, cures for all major diseases and minor diseases alike, will be attainable. Holding the key to unlocking genetic invulnerability, even at the risk of stirring controversy, the requisition of stem cell research is imperative to elongating the existence of human life.
