The Study of Stem Cells Essay - 873 Words

In February 1961 Dr. James Till, a Biophysicist, and Ernest McCulloch, a Hematologist, proved that stem cells exist. Stem cells are considered important by many scientists for their trait of being able to adjust and develop into any kind of tissue. The study of stem cells has been mainly the interest of Biologist, however, Chemists have also had an interest in the advancement of stem cells. Stem cells, as stated previously, are cells that have the potential to develop into any kind of tissue. In the body they serve as a repair system, continually dividing without limit to repair damaged tissues. As they divide the cells can either continue to be stem cells or convert into a specialized type of cell, such as, a red blood cell, a muscle†¦show more content†¦Many people believed, and still do, that stem cell research should be halted. On July 12, 1974, the 93rd Congress passes a ban on nearly all federally funded fetal tissue research. It would stay banned until the National Co mmission for the Protection of Human Subjects of Biomedical and Behavioral Research devises and implements guidelines. The guidelines would establish an Ethics Advisory Board for the research concerning fetal tissues that originate from abortions. The reason for the boards and their guidelines is because of the source of the stem cells. As implied by the statements above, the cells used and studied came from fetuses and abortions. Certain Conservatives believed that the embryonic research would lead to an increase in abortions, causing the research to be delayed. Because of the friction caused by the stem cells source, stem cell research was delayed for many years, occasionally they would be supported for a short time, only to be shut down again. It wasn’t until very recently, March 9, 2009 in fact, that President Barrack Obama lifted one of the previous president’s executive order to halt stem cell research involving human stem cells. Putting the ethical concerns asid e, another, perhaps moreShow MoreRelatedA Research Study On Stem Cell1225 Words   |  5 Pages My research about stem cells, I will be talking about what a stem cell is. Why are stem cells important from a medical perspective? How are stem cells being used today? Where do scientists get stem cells? Why is so much controversy over the stem cells? How does a zygote develop into a baby? Why a zygote is considered a stem cell? A stem cell is an immature cell that can help reproduce different types of cells throughout the body. There are three types of stem cells that I will be focusing on : adultRead MoreA Research Study On Stem Cell Research1644 Words   |  7 PagesStem cell research has covered many parts of research today and is growing progressively and becoming more common in research today. These cells have the potential to grow and develop into any other cell type in the body and form or make up the tissues of the body and organs. There are millions of people today who suffer from birth defects or diseases because of damaged cells or tissue. Stem cells give researchers the ability cure and replace almost all the cells in the body and help grow new tissueRead MoreA Research Study On Stem Cell1680 Words   |  7 Pageslife, cells make up every organ and body part of a living organism. Among various types of cells of human bodies, a stem cell can turn into any type of specialized cell of human body. A stem cell is a cell that has the ability to develop into any conceivable different kind of specialized cell type. The existence of a stem cell was first discovered by Drs. James Till and Ernset McCulloch from Canada. A stem cell can be distinguished into two types: adult stem cell and embryonic stem cell. An embryonicRead MoreA Brief Study on Stem Cell Research734 Words   |  3 PagesHuman stem cells come from a number of different places including aborted fetuses (whether that is a spontaneous or an induced abortion), stored or extra embryos retrieved f rom infertility treatment, embryos created for the purposes of research, cell lines that already exist, and taken from peripheral blood or bone marrow (CII Biotech Resource Centre, 2012). When getting informed consent from people whether individuals or couples regarding stem cell research there are a few important points thatRead MoreResearch Study On Mesenchymal Stem Cells869 Words   |  4 PagesMesenchymal stem cells (MSC) are fibroblast-like structural cells that are found in bone marrow, skeletal muscle, and other connective tissues. MSC derived from bone marrow (BM) have been shown to be self renewing and are capable of differentiation into a variety of stromal cell types including bone forming osteoblasts, fat storing adipocytes, and neurons. Another trait exhibited by BM-MSC is their supportive role in hematopoiesis (blood genesis). This behavior has been utilized to enhance efficacyRead MoreA Research Study On Stem Cell Therapy1450 Words   |  6 Pagesothers in need. Ste m cell therapy is one of the new therapies that are used to treat a disease or prevent it. Bone marrow transplants are one type of therapy that has been used for the treatment of leukemia for a while now. 1,6Stem cell therapy is used to replace damaged, diseased, or malfunctioning cells anywhere in the body with healthy cells. When a stem cell is introduced to a specific part of the body, that stem cell receives signals that tell it how to mimic the other cells around it. OneRead MoreA Research Study On Stem Cell Therapy1511 Words   |  7 PagesIntroduction Stem cells are homogeneous cells found in the human body which have potential to change into, or differentiate into a range of specific types of cells (Stoppler, 1996). The refurbishment and protection of many adult tissues are safeguarded by stem cells (SCs) which exist in the top of the cellular sorting section of these tissues (Beck, 2013). Practical assessments, such as transplantation, in vitro clonogenic assesses (technique used to study efficacy of exact agents in terms of theRead MoreA Research Study On Stem Cell Research Essay1265 Words   |  6 PagesComposition Stem Cell Research According to the Merriam-Webster dictionary a stem cell is â€Å"a simple cell in the body that is able to develop into any one of various kinds of cells (such as blood cells, skin cells, etc.).† There are two types of stem cells, embryonic and adult. The adult stem cells can can be found in brain, bone marrow, blood, etc. The embryonic stem cells come from a four to five day human embryo during the blastocyst phase (Crosta) . The controversy behind the topic usually stems fromRead MoreA Research Study On Stem Cells And Cloning977 Words   |  4 PagesMy Biology Report is going to Stem cells but in this report I am going to tell about strm cells and cloning but i am only briefly going to talk about it I will tell you facts pros and cons what is stem cells.And what it is period.But for cloniing i am just going to tell you what it is and what is bad about it.

He knows that stem cells could help cure him from his misery, so he has been fighting and fighting for stem cell research to be fully funded in America. Stem cells are cells that have the skill to change into any type of cell in the human body (Lewis). These cells could be put anywhere ill in the body to make it healthy again. Imagine all of the people with chronicle diseases and cancer being able to have hope for being happy and healthy again. Also, these stem cells can fix damaged organs
