Embryonic Stem Cells Essay

541 Words3 Pages

During the nineteenth century, it was discovered that cells could regenerate other cells. Moving on to the twentieth century it was found that cells could also regenerate blood cells. The first human histocompatibility antigens were found by J. Dausset in the 1950’s. The antigens help identify what is normal to be in the body and what shouldn’t be. During the 1960’s, the study of how tissue can be changed has increased. Stem cells have created a big interest in the past ten years. Some stem cells like bone marrow are limited to what it can do but it has no ethical problems like the embryonic stem cells. These cells are currently getting studied to be able to help with heart attacks, strokes, diabetes, organ reconstruction and so much more. Stem cells will be very …show more content…

ESCs are the most interesting. FSC and ASC are limited. Stem cells are being experimented with the heart muscles. Cardiac insufficiency is when the heart isn’t able to pump how it should. Ten thousand of these are found within years. Heart transplants are the only option right now. The problem with heart transplants are the donors of the heart. New treatments are needed so it can help people with this problem. A new treatment that is possible is Xenotransplantation. Cell therapy also could be a definite fix but it has come consequences with it. Trials with gene and cell therapy haven’t created a definite solution. Harvesting cells or of humans can only be in health centers that are approved by Public Authorities. Right now cardiac grafts in sex mismatch are being observed. Trials have been done involving cardiac muscles and mice. The experiment involved injecting bone marrow from a male mouse. The results showed that the stem cells repaired the tissue. The cytokines released could be how the tissue repaired itself. The first human trial was in 2007 using stem cells for heart disease. The patient had stem cells delivered by IV to help after having a heart

    Writer of "Perils and Promise: Destroy an Embryo, Waste a Life" , is U.S Representative Christopher H. Smith (Smith). Smith's article topic is about the research done using embryonic stem cells and destroying the embryo after instead of just using adult stem cells for research. He persuades his opinion to the reader in an extremely strong and aggressive tone. Smith makes excellent use throughout his article of all three elements of Pathos: appeals to fear and concern, appeals to emotion, and appeals to emotions and the need for self-esteem.

    For example, Alzheimer’s disease is a disease that is caused by brain cell death. Alzheimer’s does not have a cure, and the only treatment for it is medication that will slow the death of cells. However, if embryonic stem cells were used, they could replace and, theoretically, stop the death of brain cells, which would in turn, halt the disease. So overall, this treatment could dramatically benefit patients struggling through diseases like Alzheimer’s, Parkinson’s, cancer, and diabetes. Furthermore, the increase of quality of life for these living people is more than worth the possible destruction of a cluster of

    The researchers also made the cells invisible to the rest of the cells in her body or else the other cells would attack the CAR T cells because they would be considered foreign to her body. Once the CAR T cells were in the patient’s body, the results showed that the treatment was successful (Saey). This shows that gene editing can help treat cancer, which would be a huge medical breakthrough. Also, gene editing can help treat serious eye conditions. Researchers can modify mutated genes that are causing the eye conditions.

    Stem cells have the potential to cure specific diseases such as Parkinson 's, Alzheimer 's, Diabetes, and Cancer. A few years ago, you could only get stem cell transplants from specific doctors, But as of 2015 there are 170 clinics that can do the procedure. The way that they implant the stem cells into the patient 's body is by putting the cells straight into the bloodstream or by inserting the cells into the patient 's bone marrow. They extract all of the stem cells that they need and then they take out the patient 's dead stem cells and put in the donor 's healthy stem cells.

  • Persuasive Essay On Xenotransplantation

    1761 Words  | 8 Pages

    Xenotransplantation has the potential to save the multitude of people who are waiting for human organ donors. The definition of xenotransplantation is the transfer of organs, tissues, and/or living cells from another species, typically an animal, to another, such as a human being. The prefix ‘xeno’ means other or different while transplantation refers to the transfer of an organ or tissue. The controversial idea of using animal organs for humans has been studied for many decades but the major advances seem to have been made just in the last decade. The actual, successful operations have not been performed until recently since now people are opting to try out a pig heart rather than die waiting on a list for a human organ donor.
