Written Assignment 2: Biology and Technology in the Real World
Addresses course outcomes 2 and 3: • use knowledge of biological principles to ask relevant questions about the natural world • make observations and discriminate between scientific and pseudoscientific explanations 1. Select one of the following topics below. 2. Find articles related to the topic. 3. Write two pages, double spaced, excluding references. You must read the articles that you find and summarize the information they contain briefly in your own words. Extensive quotes from the article are discouraged. This assignment demonstrates the acceptable, ethical, and academic method for citing information from a public source.

These ideas definitely seem promising, but, embryonic and adult stem cells to be used for these therapies come with their own set of pros and cons. Because of a difference in their potencies, there is a variance in the ability of these two cell types to form differentiated cells in the body. Embryonic stem cells are pluripotent and when provided with the right set of conditions, can give rise to any cell type in the body whereas adult stem cells are limited to cell types of the tissue from which they are derived. Embryonic stem cell therapy is still not favored because there is a high risk factor of tissue rejection after transplantation. Current stem cell therapies focus on highly plastic autologous adult stem cells (cells that are derived from one’s own body - this reduces the chances of tissue rejection) and are either very expensive or mostly experimental (under trials). But, obtaining adult stem cells from mature tissues is challenging and maintaining their cultures in vitro is even more difficult than embryonic stem cells. Culturing becomes an important aspect because large number of cells are required for stem cell

Adult stem cells, also known as somatic stem cells, are unnamed cells found throughout the body that have the potential to divide into different cells to replenish dying cells and regenerate damaged tissues. Adult stem cells can be found in both children and adults. The research and therapy in adult stem cell does not require the destruction of an embryo unlike that of embryonic stem cells. Consequently, adult stem cell research is the less controversial of the two. It is a known fact that both areas…
January 5, 2015 Stem Cell Research What are stem cells and why are they so important? Stem Cells are cells with the ability to divide for indefinite periods in culture and to give rise to specialized cells. Stem Cells can be found in the brain, heart, skin, organs and spine. There are two types of stem cells, adult stem cells and embryonic stem cells. Stem Cell research is exceedingly useful in our society because it can help cure many diseases and help the injured. Stem cell research can contribute…
What are stem cells? Stem cells are the master cells of the human body. They can divide to produce copies of themselves and many other types of cell. They are found in various parts of the human body at every stage of development from embryo to adult. Stem cells taken from embryos that are just a few days old, can turn into any of the 300 different types of cell that make up the adult body. What types of stem cell exist? Stem cells can be classified into three broad categories, based on their…
scientist working with Adult Stem Cells in the CERN Laboratory in Switzerland. I am here for you to listen to this one request. That is for you to provide funds for Adult Stem Cells ONLY. I believe that Embryonic Stem Cells are an unnecessary loss of life in the scientific research community. I am here to not only take a stand in ethical controversies, but also in what is for the good of science. Adult stem cells are a benefit to science. Stem cells are an undifferentiated cell of a multicellular organism…
The Research of Stem Cells and Treatments Overview Sufficient research studies has shown that stem cells could be used for many reasons in the human population. Those undifferentiated cells are known to have the ability to change into specialized cell types. Further investigation will be shown about how those stem cells work, and how they may cure cancer, diseases, and other health problems. The investigation includes embryonic stem cells, adult stem cells, and umbilical cord blood banking. Positive…
Introduction Stem cells are undefined cells with the potential to become any type of specialized cells. Stem cells can be derived from embryos, fetuses, and even adult cells. Stem cells can be used to replace tissue that is damaged, or even destroyed. If used to its full potential stem cells can help to fight the effects of aging. Stem cells draw in a mass of controversy and issues on many fronts both scientific, and moral. Stem cells could eliminate the problems thought to be unsolvable, and better…
A stem cell is an undifferentiated cell, which retains the ability both to keep dividing for self-renewal of its population, and to become specialized in certain conditions. Embryonic stem cells occur in the early embryo, and have the ability to differentiate into any of the 200-plus types of specialized cells in the eventual body. Adult stem cells occur in certain tissues where they multiply rapidly as part of ongoing maintenance. In the bone marrow they produce millions of different blood cells…
Stem Cell Research and U.S. Funding The Legal Environment Adult Stem Cell research achieved its first success in the1968. The treatment of a patient with severe combined immunodeficiency disorder was a success. Adult Stem Cells have also been successful in treating leukemia’s. A patient with AIDS and leukemia was treated and cured. The donor stem cells had a gene variant that resists AIDS. The product of using stem cells is that it is ability to cure disease. The stem cells can be found…
Stem Cells (HowStuffWorks, 1998) Danielle Wark Mrs.Toope SBI 3U1 Friday, May 17, 2014 Stem Cells Are you looking to change the medical World as we know it but something is holding you back? Then you are a lot like stem cells. Our bodies contain many specialized cells that carry out many specialized functions, these cells are called differentiated cells. In contrast to this, a stem cell is undifferentiated where it’s role in our body is not yet determined. Stem cells are undifferentiated…
The Incredible Cell Stem cell research is relatively new but offers the potential to yield a cure for some of the most tragic diseases of our world. Stem cell research was initiated in the early 1900s. Since then, stem cell research has expanded significantly as researchers search for cures, but it has also generated huge public resistance to using embryonic human cells for research purposes on moral and ethical grounds. In this research paper, stem cells will be explained and an argument…
