Stem Cell Research Summary Article By Lizika Marrà ©e-Mills What are stem cells? Stem cells are identical cells that can characterize into specialized cell types. Most stem cells come from two main sources; embryonic stem cells and adult stem cells. 1. TwoTypesofStemCells a. Embryonic stem cells i. These are pluripotent cells. This means their main function is to make any other cell in the body. These cells are made from ones found in early human embryos, which are called blastocysts. ii. Embryonic stem cells are used to study how blastocysts grow in adults and how they affect other cells. iii. Embryonic cells start as a mass of cells and then grow and develop. This, in humans and other mammals is the start of an embryo that later forms the†¦show more content†¦This can help us get a better understanding of how the human body works and how to better diagnose conditions. b. Stem cells can also be used for drug discovery which can help to identify drugs which can be used for particular diseases. Scientists can grow tissue from stem cells and then to search for new drugs. This can improve drug function or alter diseases and how these drugs might affect different organs. c. Stem cells can be used for cell replacement. Again more scientists are exploring how stem cells generate tissue that when transplanted will take the place of tissue damaged by diseases and other things. One example of this type of transplantation is macular degeneration, which is now being tested in clinical trials. d. Stem cells can self repair. Scientists are research ways to stimulate the self repair of stem cells. This can make the stem cells duplicate and generate to heal damaged tissue or to prevent further damage. 4. ProcessInvolvedinStemCellResearch The process of stem cell transplantation is a long and hard one. The process of transplantation is a newly discovered one that involves bone marrow and and chemotherapy to â€Å"condition† human body and replace the damaged stem cells. The first part of the transplant process is called conditioning. In this process the patient starts to receive chemotherapy and/or radiation therapy to damage and/or destroy the bad bone marrow in the sick person. Once the stem cells are embedded into the patient the stem cellShow MoreRelatedThe Ethical Theories Of Ethical Subjectivism, Utilitarianism, And Deontological Ethics1006 Words   |  5 Pagesexplain the ethical theories of ethical subjectivism, utilitarianism, and Deontological ethics. Secondly, I will summarize the main points of my article and then act in response using the three ethical theories previously listed. I will also explain which ethical theory best represents the article. Then, I will provide reasoning as to why stem-cell research is important; and lastly, I will offer two open-ended questions. Defined Ethical Theories All the ethical theories are going to be defined usingRead MoreThe Impact Of 3d Printing On An Ethical Point Of View1185 Words   |  5 PagesThe advancements of 3D printing technology within society is advancing at such a speed The research within this assignment will focus on the conflict surrounding 3D printing (bioprinting) artificial organs with stem cells based on an ethical point of view. Throughout numerous articles, two key conflicts are expressed towards the public. The first conflict consists of the question of which stem cells will be used to create the organs. The second conflict elaborates on the possibility of creating organsRead MoreThe Growth Of The Tissue723 Words   |  3 PagesArticle # 1: Barzegari, Abolfazl and Amir Ata Saei. Tissue Engineering in Microgravity Bioreactors. BioImpacts 2.1 (2012): 23-32. Academic Search Complete. EBSCO. Web. 24 October 2014. Article Summary: The growth of the tissue can be accomplished more efficiently in microgravity. This article discussed the methods that dependent completely on microgravity. Along with that these methods also explains the various cell types such as stem cells. The ensuing builds can be utilized for poisonRead MoreUnifferentiated Cells915 Words   |  4 Pagesreprogrammed cells with acquired pluripotency†, published in 2014 and now retracted, Haruko Obokata et al. described a new methodology for the conversion of somatic cells into pluripotent cells, without genetic manipulation or DNA transfer. Somatic cells were subjected to sublethal stimuli and, therefore, named â€Å"stimulus-triggered acquisition of pluripotency† (STAP). The research consisted in introducing mouse somatic cells into a very acidic solution (low pH) or subjecting the external cell membranesRead MoreHuman Neural Stem Cell Tropism857 Words   |  4 PagesARTICLE TITLE: Human Neural Stem Cell Tropism to Metastatic Breast Cancer ESSAY TITLE: The Investigation of a therapeutic implication on metastatic breast cancer with a specialized human neural stem cell that is programed to secrete carboxylesterase combined with activated form of an ionotecan by targeting a specific tumor site and major cytokine involved in mediating susceptibility of neural stem cells to breast cancer cells. SCIENTIFIC SUMMARY: Metastatic Breast Cancer is characterized as aRead MoreIs the Use of Transgeneric Organisms Essential to the Advancement of Therapeutic Medicine?1315 Words   |  6 Pagesthat have been successfully grown with human cells and transplanted into human patients. The demand that the human population has on donor organs far exceeds the number of organs available for transplant. Genetic modification is the solution to this problem, in that, the advances being made in therapeutic medicine will save millions of lives in the future. Now that it is possible to alter the genes of an organism and to grow organs out of human cells, one can make an organism resistant or even immuneRead MoreCan Stem Cells Be Used For Cure Parkinson s Disease? Essay3847 Words   |  16 PagesIntroduction: Investigative Question: Can stem cells be used to cure a neurological disease, namely; Parkinson’s Disease? The aim of this research is to determine if stem cells can be used to cure Parkinson’s disease. I too aim to determine if such may be achieved by using stem cells that are obtained in an ethically unchallenging manner, such as by using induced pluripotent stem cells, which are created from one’s own skin, to cure the disease. I chose to conduct research into this topic as currently thereRead MoreCure For HIV1156 Words   |  5 Pagesawaited battle due to the virus lying dormant in T cells for years. Although scientists have found a protein called CD32a that lives on the surface of T cells. Due to this discovery, scientists can now use this protein to help distinguish the cells infected with HIV. This is beneficial because even though there are antiretroviral drugs that can prevent cells that are actively duplicating viral DNA from replicating, they do not attack the dormant T cells. In the past, a shock and kill therapy methodRead MoreA Comparison Of Dna Methylation Between Infants Delivered Vaginally And By Caesarian Section1714 Words   |  7 Pagesinfants delivered vaginally and by caesarian section 1 Introduction This paper, written for the course ‘Molecular microbiology and epigenetics’ is a summary of two existing articles: ‘Epigenetic modulation at birth - altered DNA-methylation in white blood cells after Caesarean section’ (Schlinzing et al., 2009) and ‘Caesarean delivery and hematopoietic stem cells epigenetics in the newborn infant: implications for future health?’ (Almgren et al., 2014). The objective is to review some possible implicationsRead MoreThe Cloning Should Not Be Banned By The Human Body886 Words   |  4 Pages Cloning Dolly, the sheep in 1996 was a momentous moment in scientific history. Scientists removed the nucleus from one of Dolly s skin cells and engineered an egg to be insert with then nucleus. This egg could have fertilized in a mothers uterus. Following this discovery, mice, pigs and cattle have been cloned based on the same concept. In 2012, a group of scientists took cloning a step further and cloned human embryos. With great certainty, human cloning will be banned by the government due
