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. You may not use online†¦show more content†¦A friend asks you. Whats all this controversy in the news about fracking and tar sands? Briefly explain to your friend how hydraulic fracturing and oil sands are used to obtain fossil fuels. Then, in more detail, describe the environmental problems involved in these processes and why they are controversial. Finally, give your opinions on possible solutions to the problems, with your reasoning backed by the references that you studied. Stem cells Stem cells are a special group of cells found in all multicellular organisms. What makes them unique and different from other cells is the fact that they are unspecialized and have the potential to differentiate into diverse cell types while still maintaining the ability to replenish themselves. Generally, these cells are divided into 2 broad categories – the embryonic stem cells that are derived from the inner cell mass of the blastocyst and the adult stem cells that are harvested from the bone marrow, umbilical cord blood or the adipose tissue of an adult. Stem cell based regenerative therapies Because of their unparalleled ability to differentiate into a number of different cell types, stem cells are an attractive subject in the field of medical science. Stem cell therapy explores the possibility of introducing stem cells intoShow MoreRelatedThe Cell Of Adult Stem Cells993 Words   |  4 Pagesproliferative cells that maintain their population size when they divide, while at the same time producing progeny that enter a dividing transit population within which further rounds of cell division occur, together with differentiation events, resulting in the production of the various differentiated function cells required of the tissue.13 This means that adult stem cells exist in small groups and are mostly undifferentiated, meaning the cells have the capability to change into one or more cell typesRead MoreCell Cells And Adult Stem Cells Essay889 Words   |  4 PagesIntroduction Stem cells have the potential to differentiate into other cells or divide to produce more stem cells. There are two main types: pluripotent stem cells and adult stem cells. The adult stem cells only produce certain types of cells and are categorised as multipotent. In contrast, pluripotent stem cells have the ability to differentiate into any body cell (Stemcellfoundation.net.au, 2015); for example embryonic stem cells were first identified by Martin Evans in 1981 at The UniversityRead MoreStem Cells And Adult Stem Cell Research882 Words   |  4 PagesStem cell are cells with the ability to divide for indefinite periods in culture and to give rise to specialized cells( Introduction [Stem Cell Information]., 2015). Stem cells, like any other cell divide, however, when stems cells divide they either remain a stem cell or become a specialized cell, for example, a neuron (Introduction [Stem Cell Information]., 2015). Stem cell research is nothing new; in fact the first bone marrow tran splant to successfully treat two siblings with combined immunodeficiencyRead MoreAdult Stem Cells Vs.

Embryonic and Adult stem cells are the only types of stem cells. Stem cell research shows a good deal of promise in the aiding of curing diseases. Both embryonic and adult stem cells show promise in curing diseases, but it is unclear which type of stem cell is more effective. The human embryo for embryonic stem cell researchRead MoreEmbryonic And Adult Stem Cell Research Essay1093 Words   |  5 Pages but he is unaware that the type of sickle cell disease from which he is suffering can be cured using stem cells. Scientists have recorded two types of stem cells – embryonic and adult. Stem cells can be retrieved not only from embryos, but also umbilical cords, the placenta, amniotic fluid, and adult tissues and organs (â€Å"Stem Cells,† 2011, p.12). Stem cell research is only a small part of a much larger field of regenerative medicine that includes cell-based therapies, gene technology, and tissueRead MoreAre Adult Stem Cells Are Been Curing Diseases?933 Words   |  4 Pagestreatable. However, the use of adult stem cells is proving to be an extremely effective method to cure a wide range of medical disorders. While little funding is available for stem cell research, the outcomes are beginning to look promising. In the article, â€Å" Adult Stem Cells Are Already Curing Diseases,† Jean Peduzzi Nelson, a stem cell researcher from Wayne State University, argues for more funding and research in the area of stem cells. She presents instances in which stem cells have worked to help cureRead MoreMedical Ethics : Adult Stem Cell Research Essay1565 Words   |  7 Pages Tennisa Saunders Medical Ethics Adult Stem Cell Research Professor December 2016 In this essay I decided to write on Stem. Initially, I began by defining what stem cell is and the different types of stem cell scientist work with. I include the medical scenario of a woman from Huston by the name of Debbie Bertrand who suffered from Multiple Sclerosis. I also included Dr. Lall, discovery of stem cells in baby teeth, because I found the article to be very interesting.

Stem cells have the ability to divide for indefinite periods in culture and to give rise to specialized cells (U.S. Department of Health and Human Services, 2009). According to the National Institutes of Health, embryonic stem cells derive from four to five day old embryos, also known as blastocyst, that have been fertilized in vitro and donated to research purposes with informed consent from the donors.

This essay hopes to adequately answer that question. Heres the scoop: As originally reported late last year in the medical journal Blood, Dr. Catherine M. Verfaillie and other researchers at the Stem Cell Institute, University of Minnesota, have discovered a way to coax an adult cell found in the bone marrow to exhibit many of the attributes
