The Promise of Stem Cell Research for Solving Complex Medical Problems Paper
The Promise of Stem Cell for Solving Complex Medical Problems - Research Paper Example It is evidently clear from the discussion that stem cell research might seem to be a catch-all solution to a myriad of clinical problems. If the public listens to certain corners of the bioethics field, stem cell research might seem to be a scientific solution that comes at a great cost to human life. Of course, most approaches to stem cells contain far more nuance than ââ¬Å"forâ⬠and ââ¬Å"againstâ⬠embryonic cell research; however, it is a polarizing subject that is divisive even among researchers in the field. The purpose of this paper is to define some of the challengesââ¬âboth ethical and scientificââ¬âposed to embryonic stem cell research, which includes looking at possible future directions for clinical practices, research agendas, and ethical systems that might oppose the use of embryonic stem cell lines. Overall, the ââ¬Å"promiseâ⬠of stem cell research includes not only the potential for benefiting mankind with novel kinds of treatment for painfu l and debilitating diseases, but also the potential for creating these treatments in ways that do not harm human dignity. First, a distinction should be drawn between embryonic and adult stem cells, particularly with regard to differences in their potentials to grow and regenerate tissues. Stem cells in general are a rare subset of primitive cells that, at the single-cell level, can self-renew as well as give rise to mature, differentiating daughter cells. According to the NIH, embryonic stem cells are grown easily in culture, while adult stem cells are rare in mature tissues. Accordingly, isolating these cells from an adult tissue is difficult, and methods to develop more cells in cell culture have not yet been developed. This distinction is significant insofar as large numbers of cells are needed for stem cell replacement therapies. In other words, adult stem cells cannot provide a sufficient level of coverage for stem cell research, let alone stem cell treatments on a public leve l. Therefore, stem cell research is normally biased toward the use of embryonic stem cells. Such stem cells are taken from embryos that are fertilized in vitro. The development of cells in a laboratory setting is known to scientists as ââ¬Å"cell culture.â⬠Embryonic stem cells are grown by transporting cells from a pre-implantation embryo into a culture environment that holds a nutrient-rich base known as a culture medium. Over the process of development, the cells divide and coat the surface of the dish into which they were transported. Once a cell line is developed, the original stem cells can produce millions or perhaps billions of embryonic stem cells for researchers to utilize in making discoveries and potentially treating diseases. Stem cells that proliferate in a cell culture of an extended period of time but have not differentiated into a specific kind of cell are known as ââ¬Å"pluripotentâ⬠(meaning, literally, not constrained toward a specific developmental p athway). These cells are truly useful because they can be
