Most cells in our bodies are specialised to do a particular job. Like white blood cells are good at fighting off invaders, but they can’t carry oxygen like red blood cells. Stem cells on the other hand have the remarkable potential to develop into many different types of cell in the body. In addition, in many tissues they serve as an initial repair system, dividing without limits to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential to remain a stem cell or become a more specialised cell.
They can be distinguished from other types of cell by two characteristics. First, they are unspecialized that can renew themselves through cell division. Second, under certain conditions they can change to become organ or tissue cells with a specialized job. In some parts of the body like bone marrow stem cells regularly divide to replace worn out or damaged tissue.
Embryonic stem cells are thought by most scientists and researchers to hold cures for hundreds of immune system and...

Human Embryonic Stem cells and Induced Pluripotent Cells Essay - Human Embryonic Stem cells and Induced Pluripotent Stem Cells are two modern methods of research; and treatment being aimed at the treatment of cancer, and many degenerative and genetic diseases. Stem cells are cells with the ability to develop into a cell of a different type, some types of stem cells are able to differentiate or change into a cell which is specific and functional to a specific tissue or organ system. This unique ability is what many scientists are trying to focus towards regeneration of different tissues, or the creation of new tissue to help cure, or treat diseases like cancer, multiple sclerosis, and alzheimer's....   [tags: stem cells, human embryonic, cells]

Supporting Embryonic Stem Cell Research Essay - Supporting Embryonic Stem Cell Research Scientific research has the ability to help the terminally ill and disabled. Some people find this research is morally wrong. If this research helps people with disease and disability would you condone it. Today in The United States there is controversy facing embryonic stem cell research.People are dying because of the legal and moral obstacles involved in embryonic stem cell research. American citizens with illnesses and disease could be treated if this research was to continue at a much faster pace....   [tags: Embryo Embryonic Stem Cell Cells Essays Papers] 1525 words

Embryonic Stem cells Essay - Introduction Stem cells are undifferentiated cells found in multi-cellular organisms that can proliferate by mitosis to produce either more stem cells or specialized cells that differentiate into the different organs and tissues. In scientific research, stem cells have been obtained and developed from different sources which include: Embryonic Stem cells Embryonic stem cells (ESC) are pluripotent cells that have the potential of proliferating indefinitely into any of the 3 germ layers of cells - endoderm (which differentiate further to specialized cells of the interior stomach lining, gastrointestinal tract, the lungs), mesoderm (which differentiate further to specialized cells of the muscle...   [tags: bone marrow, mammary gland]

A Scientific Explanation of Stem Cells and Stem Cell Research Essay - In general, a cell can be defined as a stem cell if two basic criteria are met. First, stem cell is capable of self renewal for indefinite period throughout life while maintaining undifferentiated state, i.e., the cell can divide and produce two identical daughter cells and thereby maintains the stem cell pool. Second, stem cell possesses capacity for differentiate into specialised and functional progeny under the right conditions, or given the right signals. It may divide asymmetrically to yield an identical cell and a daughter cell that acquires a particular cell type’s properties, such as morphology, phenotype and functional physiology that classified it belongs to a particular tissue (Bu...   [tags: Science, Stem Cells, Stem Cell Research, ] 610 words

Embryonic Stem Cells Research Essay - Embryonic stem cells research is a very conflicting subject in the United States. Some people think that it is morally and religiously incorrect as they are killing a human life at the first stage of life. While some think it is ok because the human life to them starts at the stage of the fetus. In this paper we are going to discuss the total aspect meaning: how the government takes playThe intention of this research paper is to inform about the benefits of animal testing for humankind through the development of medical treatments and the quality of life throughout history....   [tags: Biology, Science Experiment] 2779 words

Embryonic Stem Cell Research: The Pandora’s Box of Science Essay - There has been controversy surrounding science ever since the first scientific journal was published in 1665. Most people have an opinion on hot-button scientific topics today, such as climate change and Darwinian evolution. Technology and science will forever be connected, and scientific technology has changed countless lives, evolving exponentially throughout the history of time. The average life expectancy has more than doubled from thirty three years old in the Upper Paleolithic Era to sixty seven years old today....   [tags: cells, technology, genetics, ethics]

Embryonic vs. Adult Stem Cells in Research Essay - Embryonic vs. Adult Stem Cells in Research   Why is the mainstream media significantly downplaying exciting scientific discoveries with adult stem cells. This essay hopes to adequately answer that question. Here's 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 that supposedly make embryonic stem cells irreplaceable to the development future "miracle" medical therapies(Catherine)....   [tags: Argumentative Persuasive Topics] 1606 words

Human Embryonic Stem Cells Essay - ... Those that share this ideal, argue that, “An early embryo that has not yet implanted into the uterus does not have the psychological, emotional or physical properties that we associate with being a person. It therefore does not have any interests to be protected and we can use it for the benefit of patients. On the other hand, advocates for this research type argue, “Fertilized human eggs are just parts of other people’s bodies until they have developed enough to survive independently. The only respect due to blastocysts is the respect that should be shown to other people’s property....   [tags: stem cell research, government] 2149 words

Embryonic Stem Cell Research Essay - Americans are asked by the media to support embryonic stem cell research (ESCR) that uses human embryos. Many Americans favor ESCR because of the potential for benefiting people in need, people racked by disease. This essay goes beyond the emotional issues surrounding ESCR and informs the reader of the scientific background so that he is capable of making a well-informed decision about ESCR.   In August of last year, President Bush approved the use of federal funds to support research on a limited number of existing human embryonic stem cell lines (Bush)....   [tags: Argumentative Persuasive Topics]

Introduction: “Embryonic stem cell research offers both great promise and great peril.” - President George W. Bush, Aug. 9, 2001 Stem cell research is not new but only recently has it become widely known to the public because the benefits of the technology are coming closer to reality; the field of stem cell biology is advancing at an incredible pace with new discoveries being reported in scientific literature on a weekly basis. Scientists first announced a method of growing embryonic stem cells in a laboratory in 1981, but the cells were from a mouse....   [tags: Embryonic Stem Cell Research Regulation]
