Are Animals the Future of Human Organ Transplants?
Can animals be the future of organ transplants? Thought the research concluded many pros and cons of this. Pros : Decreasing the number of people needing transplants, using the ability of the monkey to see how the organ may react in us. Cons : Harming the animals, Animals becoming too much alike to humans, receiving diseases the animals may carry. Although humans need organs are the animals the way to go? If animals can actually be used for the future of organ transplants in humans,many lives would be saved for the people in need of the organ or organs.
About 2 dozen Americans die each day in need of a transplant. (Fikes) In 2014 there was 317 million people living in United States of America

“Worries over animals whose brains contain some human cells and what might happen if the cheras were able - and allowed - to reproduce.” (Bernstein) “pigs and other animals may contain viruses and other pathogens that could be transferred to transplant patients” (Bradley). “The complexities of the immune system and the possibility of infection by pig viruses are formidable..”( Reardon 152). Many regulators are uneasy about the safety and the risk of ig organs transmitting diseases to immunosuppressed human (Reardon 153). “Patients died within a few months, usually because the immune system attacked and rejected the organ” (Reardon). “Even if pigs could be kept entirely sterile, the ig genome is sprinkled with dozens of dormant porcine endogenous retroviruses (PERVs) and studies conflicted as to whether these could become active in humans “ (Reardon 153). PERV problem is a major safety concern. The virus replicates poorly in human tissues and the risk of spreading it is virtually non-existent.” (Reardon 154) “Most major epidemics started with an animal pathogen then jumps to humans.“ (Reardon 154). As a consequence many people can be harmed in the medical discovery of using animals for …show more content…
Human stem cells are put into animal embryos.(Fikes). These are called chimeras. A chimera is a single organism composed of cells of different zygotes. This can result in male or female ergano. “One route that Izpis uses is to put the region-specific pulpotomy stem cells into an animal embryos very early in that embryos development process. This strategy carries the risk of pluripotent cells migrating elsewhere..” (Fikes). Another route would be to coverent the pluripotent stem cells into a more mature ‘progenitor’ cells that have partly differentiated. These progenitor cells can only become one one organ.” (Fikes). According to Thompson “when precursor tissue from 16-day-old rabbit embryos is implemented in an adult rabbits, it develops into an adult kidney, connecting itself to the host of the blood supply.” “The adult rabbits did not reject the foreign kidneys because the embryonic tissues was transplanted before it had producing the protein that would alert a host’s immune system to foreign cells” (Thomson) . One of the first stages of the method that American Scientist use involves genetically knocking out an organ in the animal embryo. “The scientist then injected human stem cells, which they hope will replace the missing organ before putting the embryo in the womb of a female pig or sheep.” (Oliver). In the meantime many people are still dying awaiting a

    Embryonic stem cells, which are different from the iPSCs described here, have faced roadblocks in the form of government defunding their research and the general population raising concerns about the morality of using embryos for research. They also faced challenges when scientists became too optimistic, and hoped the stem cells would prove effectively therapeutic, rather than just a means to perform drug tests. So far these attempts have failed in…

    The Truth Behind Purchasing Illegal Organs for Transplant The US Department of Health and Human Services reports that an average of 22 people die every day waiting for a donated organ (HRSA). As a result, desperate and wealthy people are willing to pay thousands for black market organs. An illegally purchased kidney alone sells for between 30,000 and 100,000 in America (Interlandi, 2009). However, the donor is likely given less than a tenth of that money.…

    The need for organ transplants are high in demand, but the aren’t many if any people who are willing to donate their organs for medical reasons. There are waitlists for people in need for transplants but many die before hearing any good news. People and families are put in a tough position when making this decision. Its there a way to make it easier to have and organ supply? If so what are the options that one has that is still willing to honor their wishes?…

    In the article of Animal Farming: Growing Human Organs, Andrew Hitchings discuss the issues of organ shortages in the United States. Hundreds of citizens become an addition to the waiting list for organs every day, however even if received one, the complications do not stop there. One contradicting issue that surfaces is the genetic relationship between one’s immune system and organ. One particular method that can resolve this issue of preventing the immune system’s rejection of organs is the growth of new organs from the cells of a patient. With these scientists are capable of transforming human cells into induced pluripotent stem cells; which could possibly evolve into any cell sort.…

    In 1981, “Martin Evans of Cardiff University, UK, then at the University of Cambridge, is [was] first to identify embryonic stem cells - in mice” (“Stem Cell Timeline: The history of a medical sensation”). The cloning of Dolly, a Finn Dorset sheep, proved that cloning of mammals was possible when using a procedure known as somatic cell nuclear transfer (SCNT). Less than a decade later, a great breakthrough occurred when James Thomson with a group of scientists found the exact mixture and the right technique to withdraw stem cells from an embryo while keeping them viable. “By using the SNCT procedure to produce human embryos genetically matched to patients and using the techniques developed by Thomson to grow human embryonic stem cells, scientists hope one day to be able to replace or regenerate failing human cells and tissues without complication of tissue rejection” (Langwith 17). Thomson’s work laid a foundation for stem cell therapy, where healthy cells will replace diseased or dysfunctional cells.…

    Sorry to hear about what happened, but don’t let it get you down! I heard that you’re apprehensive about the stem cell therapy your doctor was pitching to you, and well, it sounds like it has real promise. There was even a paralyzed man who regained his ability to walk after a knife attack separated his spinal column. He owes his recovery to a pioneering procedure that implanted stem cells from his nose and nerve cells from his ankles to his spinal cord. I really believe that jumping on this clinical trial that your medical team recommended you for is an excellent idea that holds great promise.…

    Donor tissue should be removed within 12-24 hours of death. The optimal death-to-preservation time is 12-18 hours. There is an attempt to age-match donors and recipients. Corneas from infants (3 years and under) are used only very occasionally, even for pediatric transplants, as they are associated with surgical, refractive and rejection problems. Most surgeons do not use corneas from donors younger than 24 months, as these corneas are extremely flaccid and can result in high corneal astigmatism and myopia postoperatively.…

    There are many challenges to successful organ transplants, including matching a recipient and a donor based on matching genetic variability. It is extremely difficult to match MHC perfectly with a donor and a recipient as there are many locations where genetic differences can still cause a rejection reaction by the recipient. A familial donor is usually the closest to a perfect genetic MHC match that a recipient can find. The closer the match of genetic variability, the better the chances that the graft or transplant will be a success. When the MHC does not match between the donor and recipient, the recipient’s body is likely to perceive the transplant as a foreign invader and launch an attack of the immune system on it.…

    Pigs and primates are currently being considered as a source of organs for xenotransplantation. The pig is a model organism for this type of transplant because it has decreased time needed to reproduce and mature, and has organs very similar in size to humans. There are multiple barriers, however, that xenotransplantation must overcome in order to be successful. The most obvious problem arises because host and donor are different species, and therefore contain very different antigens in their bodies. This means that there is simply more for the immune system to identify as foreign and destroy, increasing the risk of organ transplant rejection.…

    Stem Cell Research Paper: Human Embryonic Stem Cells or (hESCs) Human Embryonic Stem Cells or (hESCs) are taken from human embryos, however these embryos are not normal ones. The (hESC) are embryos that were fertilized in a process known as in vitro fertilization. In vitro fertilization is usually done in a clinic of some sort and are then given to researchers for research with permission from the people who have donated. The human embryonic stem cells are not created from a woman, they are created inside of a lab. The process of creating hESC’s is called Cell Culture.…

    Often called into question is the validity of the argument that human cells and tissues are the property of the hosts they came from after being removed from their body. To label parts of the human body, our anchor to this world, as personal property is very difficult. Even more difficult is deciding to whom these cells belong to after they are no longer a part of the person they came from. It is important to look at the benefits of research on the cells of people in order to help others. However is it not equally as important to analyze the inhumane nature required to take the cells of another human being to research and profit without the patient's informed consent?…

    However, the applications of animal research to human medicine are limited and often useless. Dr. Aysha Akhtar identifies “three major conditions [that] …. explain why animal experimentation, regardless of the disease category studied, [fail] to reliably inform human health: (1) the effects of the laboratory environment and other variables on study outcomes, (2) disparities between animal models of disease and human diseases, and (3) species differences in physiology and genetics” (“The Flaws and Human Harms of Animal Experimentation”). These conditions are irresolvable hindrances to the advancement of human medicine; it would be more efficient and beneficial to humans to explore innovative technological alternatives that resemble human physiology more closely. In addition, the idea of sacrificing the welfare of animals to advance the welfare of humans is flawed in that it necessarily places more weight on the rights of humans, which violates the deontological view on the rights of sentient beings.…
