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

    the de- mand for organ, eye, and tissue donation still vastly exceeds the number of donors. A national study commissioned by DLA in 2004 showed that 91% of adults support the idea of donation, only one in three is aware of steps for committing to becoming a donor, since procedures differ from state to state. More than 123,000 men, women and chil- dren currently need lifesaving organ transplants. Every 10 minutes another name is added to the national organ transplant waitlist. Sadly, an…

    the ghost hearts constantly harvest organs from the newly dead by re-engineering them. Doris is the director of the regenerative Medicine Research for the center of Cell and Organ Biotechnology at the Texas Heart Institute. Dr. Taylor worked on methods of decellularization and in 2008 she perfected the method. Decellularization is taking all the cells out of the organ leaving it with the lipids, sugar, and proteins. Ghost heart or a ghost-like shell of an organ can be personalized for individuals…

    Every day 18-22 people die waiting for an organ, and “there are now more than 105,000 people on the waiting list for solid organ transplants (womenshealth)”. The organ crisis only continues to grow as the population increases. In fact, a new name is added to the waiting list about every 10 minutes (facts). The use of 3D organ cloning is an ethical alternate to full body cloning to aid in the organ shortage crisis in this country. Cloning Cloning involves taking DNA from a cell, and implanting…
