Essay on Stem Cell Research Scientific Advancement vs....

Introduction to Stem Cells As improvements in scientific technology and techniques allow for better observations and insights into the natural world, so to do advancements in medical research occur on a seemingly daily basis. On such research topic that has found itself the center of a global debate is the issue of stem cell research. Hailed by some as one of the most dynamic areas of research ever to exist, it is thought to be the next big â€Å"revolution† in medicine, surpassing even the advent of anesthesia and antibiotics (Towns, 2004). Though the reputation does not come without controversy, stem cell research can be found in the headlines of news publications for changes in policy or position on the topic equally as much as†¦show more content†¦Though stem cells can be harvested from a variety of sources, human embryonic stem cells culture lines are the type most often associated with stem cell research by the media. Donated by consenting couples, embryonic stem cells are harvested from left over embryos of the in vitro fertilization process (University, 2004). A fertilized egg is allowed to proliferate for 4-5 days until it reaches the blastocyst stage of development. At this point the embryo consists of a hollow ball of cells with an outer layer, called the trophectoderm, and an inner cell mass on the inside. As this inner cell mass gives rise to all three germ layers present in a fully developed human, the cells are referred to as being pluripotent, and are the target of stem cell harvesting (Towns, 2004). Most of the controversy associated with embryonic stem cells arises because the trophectoderm must be destroyed in order to get to the inner cell mass, effectively killing the embryo as well. Another source of stem cells that does not raise nearly as much controversy are adult stem cells found in various tissues throughout the mature body. In fact, therapeutic medical techniques have been in practice for over a decade in the form of bone marrow transplants for patients suffering fromShow MoreRelated Stem Cell Research Essay1303 Words   |  6 PagesStem Cell Research In light of the continued advancement of technology and research in the medical field, there have been some groundbreaking developments that have been heralded as indications that scientific research can produce remarkable results when it is integrated with technology. Since the turn of the 20th century, major breakthroughs like the discovery of DNA and the development of anti-retroviral drugs for HIV/AIDS have been cited as the reason why scientific research especially in theRead MoreThe Debate Over Embryonic Stem Cell Research1690 Words   |  7 Pageshas been far from reality until the research from embryonic stem cell therapy surfaced. Since former president George W. Bush banned federal funding on embryonic stem cell research in 2001 it has caused a halt in advancements and caused controversy in the public. According to an article by Beau Watts, an accredited physician; embryonic stem cells are pluripotent cells (Beau Watts). This means they have not decided what function they perform yet. Since the cells do not know the function, it can beRead MoreAre Pregnant Women Fetal Containers?983 Words   |  4 PagesThe themes surrounding abortion tend to generally scathe on a surface level and truly uncover all the underlying themes of the popular topic, the articles â€Å"Stem Cells, Sex and Procreation† by John Harris, â€Å"A Defense of Abortion† by Judith Thomson, and â€Å"Are Pregnant Women Fetal Containers?† by Laura Purdy all discuss the theme of the woman’s and fetuses health and the consequences that can come with both keeping and rejecting the a fetus.

Engineers have been working on new technology that will utilize stem cells in order to save lives and treat diseases. The stem cells that are used for treatment are called embryonic stem cells. Embryonic stem cells are formed from five-day old human embryos that the embryos are essentially human beings (In Stem-cell Research† Para. 3). The usage of such stem cells has causedRead MoreA Research Study On Stem Cell Research2115 Words   |  9 PagesStem cell research, through its ethics, methods, and funding, has caused great controversy over the past several decades. Scientists, medical specialists, religious groups, spiritual groups, the government and the public have devoted a major interest in t his subject. Some portray stem cell research as a dangerous, inhumane study whereas others see it as a growing beneficial factor for opportunity of the advancement of the medical world. Stem cell research has been proven to aid various diseasesRead MoreStem Cell Research Vs. Cloning1366 Words   |  6 PagesIntroduction: Stem Cell Research vs. Cloning Stem cell research entails the development and use of human embryos and stem cells. After the embryonic stem cells are taken from aborted fetuses or fertilized eggs, scientists study the cells. Dating back 30 years, scientists began their first attempts of deriving embryonic stem cells from the embryos of a mouse. After examining details of the biology behind mouse stem cells, scientists moved onto the biology of human embryos. Through in-vitro fertilizationRead MoreThe Legal Ownership Of A Cell1092 Words   |  5 Pageswhether individuals have legal ownership of the cells that are extracted from their bodies and used for research. Should people who donated their cells be compensated for the findings based off them? To what extent do people have control and benefits from donating their cells to science? Who has the right to have access to other people’s cells and for what purposes will they be justified and legal? B.
