Stem Cells The Origin Of An Organism s Life Essay

Stem Cells â€Å"In the beginning, there is the stem cell; it is the origin of an organism s life. It is a single cell that can give rise to progeny that differentiate into any of the specialized cells of embryonic or adult tissues.† This is a very simple explanation of stem cells by Dr. Stewart Sell, a cancer researcher. Stem cells are more or less blank cells. They are identical cells that can adapt to specialized cell types. There are two types of stem cells according to the U.S. Department of Health Human Service â€Å"embryonic stem cells and non-embryonic somatic or adult stem cells.† In this paper, I will touch on roughly every aspect of stem cells. Stem cells can come from several places. Embryonic stem cells come from embryos; they are fertilized in labs. It is important to note that the eggs are not fertilized in a woman s body. At the time of removal, the embryos are at least three days old. The U.S Department of Health Human Service defines an adult cell as â€Å"an undifferentiated cell, found among differentiated cells in a tissue or organ.† Before removal, the role of the adult stem cell is to preserve and mend the tissue of its host. There are multiple ways to harvest stem cells. The Canadian Cancer Society list several ways that stem cells are removed. Stem cells can be taken from bone marrow, blood, and umbilical cords. The Canadian Cancer Society describes the process of donating stem cells through blood. â€Å"A catheter (thin tube) is placed in a large vein inShow MoreRelatedStem Cells : Justification Of Utilization Of Stem Cell1696 Words   |  7 PagesAnvesha Mukherjee Hong GT Biology 9-1 19 February 2016 Stem Cells: Justification of Utilization of Stem Cells in Injuries/Paralysis Habitually, the majority of significant scientific discoveries that have occurred over the course of human history have been the center of fierce debate and controversy for one reason or another. From radical perspectives such as the Earth’s orbital around the sun to the theory that the planet isn’t geographically flat, scientists are often at the focal point of ethicalRead MoreStem Cell Research And Cures1703 Words   |  7 PagesName Professor Class Date Stem cell research and cures Stems cells are cells that have the ability to differentiate into specific ones. They divide through mitosis and can only be found in organisms that are multicellular. Mammals have two types off stem cells: embryonic stem cells which are obtained from the internal cell mass of blastocysts and adult stem cells which are located in different tissues.

How can the use of these cells benefit us and how exactly are they acquired? Believe it or not stem cells have been in play when it comes to medicine since the 1950’s in France (Steenblock 1). This topic is very controversial and I surmise that it is strongly due to the lack of knowledge when it comes to stem cells and their importance. I, myself, am very intrigued by stem cells and my goal is to define whatRead MoreGenetic Engineering And Its Effects1592 Words   |  7 PagesA future with no more disease, no more limitations to what we can or cannot do, the making of a superhuman, playing God. Scientists can now make humans better than ever by improving their bodies by changing the cells in your body. Genetic engineering can also prevent long-time diseases from continuing in a family and help treat many illnesses. Though it can help many issues, it brings up many problems if used improperly and often abused. Genetic engineering harbors more moral and ethical issues thanRead More Human Cloning Should be Condemned Essays594 Words   |  3 Pages Human Cloning Should be Condemned nbsp; On November 25, 2001, the news that a firm called Advanced Cell Technology had created human embryos by cloning added new urgency to Congresss and the nations deliberations on this issue. nbsp; This past summer, by a 265-to-162 margin, the House of Representatives passed a carefully worded ban on human cloning (H.R. 2505) which President Bush has said he will sign into law.

The organisms falling under the eukaryotic kingdom of Plantae are known to have arisen in the same time period as those in the eukaryotic kingdom of Animalia—the Paleozoic era, about 500 million years ago (MYA) (Raven et al., 2008). Despite their chronological resemblance, their evolutionary diversity is especially great in their most advanced organisms—humans and seed plants. One key systemRead MoreSkills For Health Science Coursework 20161243 Words   |  5 Pagesproteins are very important! The HGP allowed the identification of some of these proteins, such as insulin, which is ‘a peptide hormone produced by beta cells of the pancreatic islets,’ (En.wikipedia.org, 2016). Insulin controls the level of glucose in the blood in individuals who don’t produce enough, or any, of it and allows these individuals to lead a life that is as close to normal as is possible. Due to the identification of the genes, and therefore, the amino acids that make up insulin, because ofRead MoreEthical And Philosophical Nature Of Human Rights2452 Words   |  10 Pagesthe course themes of Ideology and Inquiry, and secondly Origins and Politics of human rights.
