Argumentative Essay on Stem Cell Research Essay - Paper
Stem Cell Research One of the numerous scientific topics that creates a great divide between Americans and political party platforms is the approval or disapproval of stem cell research. There is very firm support and opposition to this topic, and it can often provoke heated discussions amid the general public and those in academia. The core of the debate specifically revolves around embryonic stem cell research and the ethical implications that come with experimentation on human embryos. When. Stem cell technology is a rapidly developing field that combines the efforts of cell biologists, geneticists, and clinicians and offers hope of effective treatment for a variety of malignant and non-malignant diseases. Stem cells are defined as totipotent progenitor cells capable of self renewal and multilineage differentiation.1 Stem cells survive well and show stable division in culture, making them ideal targets for in vitro manipulation. Although early research has focused on haematopoietic stem cells, stem cells have also been recognised in other sites. Research into solid tissue stem cells has not made the same progress as that on haematopoietic stem cells. This is due to the difficulty of reproducing the necessary and precise three dimensional arrangements and tight cell-cell and cell-extracellular matrix interactions that exist in solid organs. However, the ability of tissue stem cells to integrate into the tissue cytoarchitecture under the control of the host microenvironment and developmental cues, makes them ideal for cell replacement therapy. In this overview, we briefly discuss the current research and the clinical status of treatments based on haematopoietic and tissue stem cells. Limbal stem cells have been described at the junction between the cornea and These cells are known to be progenitors of corneal epithelium. Keratolimbal allografts are a promising treatment for bilateral blindness,49 and limbal stem cells can now be safely obtained from living related
The thing that makes stem cells so useful is that not only can they become almost any cell in your body but they also have the special characteristics to be able to self re-new or multiplying while still keeping the potential to become useful cells for our body. Con: When it comes to ethics, we cant compromise, and using embryonic stem cells is a step too far. Every disease cured due to stem cell research is bought with blood as surely as the research done during the Holocaust was. Dont let this nightmare go on any longer! Write to your representative today! Nov, 2010 Embryonic Stem Cell Research Over the last decade the use of stem cells has been a controversial and heated topic. Debates have exploded over every aspect of stem cell research in nearly every region of the world. Every aspect of stem cell research has come under debate in nearly every region of the world. It has been speculated by scientists that stem cell research may have the power to potentially cure incredibly harmful diseases or even regrow organs. Ethical controversies involved. Dendritic cells have a pivotal role in the elicitation and regulation of antigen specific, major histocompatibility complex-restricted T cell responses and are thought to be the only antigen presenting cells able to prime naive T cells.
Haematopoietic stem cells themselves are also a promising target for gene therapy. Haematopoietic stem cells have been made resistant to one or more cytotoxic drugs22 with retroviral transfection of the multidrug resistance gene (MDR1). This should help circumvent the myelosuppressive effects of standard regimens of Haematopoietic stem cells can also be genetically marked to allow assessment of patterns of cell survival, localisation, and function after bone marrow This strategy has already been used with retroviral Double genetic marking is also being used to determine the long term effects of different protocols of cytokines given to promote bone marrow regeneration after cytoablative Gene transfer into haematopoietic stem cells represents a novel approach for treating some genetic or acquired diseases. So far, transduction of genes into humans using haematopoietic stem cells has shown low efficiency, especially in the quiescent stem cell Because of the embryonic stem cell research. Embryonic stem cell research came from identical inner mass cells of a human embryo.
Embryonic cells are able to grow into all derivatives of these primary germ layers ectoderm, endoderm, and mesoderm. Embryonic stem cell research would be a good thing for humans because human embryos for stem cell research can help a number of patients, they can be used by scientists to find cure for several medical conditions, and the stem cell research may be a treatment. We begin with a free initial consultation to understand our clients business goals and analyze their needs. We always ensure that their project requirements are fully understood before gearing up for the project. Well need as much information about their business in order to develop an appropriate theme. Stem Cells Stem Cells are fundamentally cell templates. These cell templates are used to create all the cells in our body. Stem cells under the right circumstances are manipulated into other cells, such as mussel cells and liver cells.
Dendritic cells can be derived from CD34+ precursors in response to granulocyte macrophage colony stimulating factor and tumour necrosis factor α and from monocytes cultured with granulocyte macrophage colony stimulating factor and In vitro generated dendritic cells (fig) that have been transduced with genes coding for tumour specific antigens or pulsed with tumour specific antigen or peptide could be useful for induction of cytotoxic T cell Dendritic cell tumour vaccines could be important future therapeutic tools; phase II clinical trials are under way and show limited On the other hand, the migration and function of dendritic cells derived from liver in an allogeneic environment may be seminal in the development of donor specific 20 Genetic engineering of dendritic cells to express immunosuppressive or immunoregulatory molecules may provide a novel method to promote graft tolerance, reducing dependence on systemic Your conclusion is the summation of everything youve argued in the body of your essay, so make sure you briefly give a summary of your most important points. Then move on to call your readers to action.
Essay on stem cell research - The adult bone marrow also contains mesenchymal stem cells29 which are involved in the regeneration of mesenchymal tissues such as bone, cartilage, muscle, ligament, tendon, adipose tissue, and stroma. Although human mesenchymal stem cells have been isolated, it remains unclear how basal nutrients, cell density, spatial organisation, mechanical forces, growth factors, and cytokines control their Isolated human mesenchymal stem cells constitute a single, phenotypically distinct population and are uniformly positive for SH2, SH3, CD44, CD71, CD90, CD106, CD120a, and CD124. They are also negative for CD14 and CD34 and can be induced to differentiate into adipocytes, chondrocytes, tenocytes, and osteocytes. Transplantation of mesenchymal stem cells into tendon defects in rabbits can significantly improve biomechanical properties of the damaged

science has achieved tremendous successes in different fields. In
this respect, researches in the field of genetics are
particularly noteworthy because they can start a new era in the
medicine and science at large. However, today, the research of
stem cells and their use in the modern medicine often confronts
the opposition from the part of the public as well as
specialists. In spite of a considerable progress in the stem
cells research, it still. The existence of prostate stem cells is
still a matter of Nevertheless, the concept is interesting,
mainly because of the possible analogy between effects of
androgens on the prostate stem cells and that of cytokines on
haematopoietic stem cells. Prostate stem cells could have
important implications in the development of prostatic Stem cell
research has perhaps been the most controversial talks of birth
after abortion. Stem cell research has much potential, but also
has its issues. The issues particularly affect morals and
religious beliefs around the world. Stem cell research has the
potential to cure or fix many diseases and problems relating to
our body. At the same time some cells are killed and the
religious believe that the soul exists even as a stem cell at
that size. There are two most common stem cell types. Embryonic.
