That means there are more than 20 million animals who could be at a high risk of abuse or neglect in the name of research. 15 What are the implications of the lack of transparency with regards to industry research in transgenic animals and biopharming? http://www.visionlaunch.com/transgenic-animals-pros-and-cons/, http://www.transgenicanimals.info/pros-and-cons-of-transgenic-animals/, http://apecsec.org/transgenic-animals-pros-and-cons/. , 1998; Mansour, 1990; Schnieke et al., 1997). Animal testing may provide safety benefits for new products, but some of the items that are tested will never be used. But still, several research reports have been published that conï¬A?rming sperm from many species, including livestock, poultry and ï¬A?sh, can be used as vectors to deliver transgenes into the animal genome (Smith and Spadafora, 2005) In this technique, DNA was mixed with sperm cells prior to in vitro. This prospective is emphasized by the various developments of SMGT variant protocols. Since the coat color of the parental embryonic cell strain is unrelated to that of the host embryo strain, mice in which both strains contribute to the development will exhibit a mix of two coat colors. The development of micromanipulation equipment allows the direct injection of DNA into mammalian cells and these was more efficient than gene transfection method (Diacumakos, 1973), (Capicchi, 1980), (Graessimannet al, 1979). It is the process of animal testing that is done under the guise of research to benefit humanity, but the applied research may have little or no concern to the animals involved. According to Petfinder, the total cost of caring for a single dog could be over $9,000 per year. Many of those animals are purposely bred for the experiments being performed as well, which means millions of animals are at a higher risk of suffering from abuse or neglect in a field that is often poorly regulated. Despite the number of successful experiments and groups who believe in the benefits of transgenes, there are still sectors that believe otherwise. Here are some of the additional pros and cons of animal research to discuss. Embryo stem cells are classified into three type’s embryonic carcinoma (EC) cell, embryonic stem (ES) cell and primordial germ cells or embryonic germ (PGCs) cells. Although some people will take an “ends justifies the means” approach to this situation, we must at least look at the various processes involved to determine if there should be a universal protocol that researchers follow. Some animals are almost carbon copies of humans. Though, the difï¬A?culties in reproducibility and the lower efï¬A?ciency in integrating foreign gene into the animal genome resulted in substantial disagreement for several years. Thus, such animals are utilized to conduct clinical trial research. Social Implications of Transgenic Animals Are Transgenic Animals Ethical? Chimpanzees were popular to use in the past, and still are in some areas of the world, because their genetic profile is 99% similar to a human. Pro: Helping Economy Con: Transplantation Risk Pro: Medicinal Value Pro: Environment Healthy Manure Con: Unpredictable Pro: Agricultural Profit Pro: Saving Animals Con: Unethical Con: Animal Cruelty Pro: Transplantation Transgenic Animals Pros & Cons 1. Dolly the sheep, created by Keith Campbell and Ian Wilmut, was born in 1996. It is given that not all experiments tried would succeed, which makes the lives of animals at risk. , Jaenisch and Mintz were study on healthy mice by microinjecting SV40 DNA into the blastocysts which were copies of foreign viral DNA (Jaenisch and Mint, 1974) afterward; it was revealed that germline transmission of viral DNA into the animal genome could be attained by directly infecting preimplantation stage embryos with Moloney leukemia viruses (MLV) (Jaenisch, 1976). How will this change evolution? Is it ethical to created "diseased" animals? Unethical Use of Animals. This is done through their milk in order to make easier purification, increase production and proteins(Adam, 2003)as a typical example genetically altered goat that produce human antithrombinI (hAt)which is a serum glycoprotein (Baguisi et al., 1999) preventing from blood clot. Many of the items that are tested are never used. The decision whether to trust the advocates or believe in the negative impact as claimed by critics will remain by weighing the pros and cons first to avoid regrets. After 1950s things were changed to molecular level because of the discovery of DNA and other recombinant technologies. In agricultural application of transgene, the changing the composition milk that can increase the production of certain protein and growth factor in the deficient milk can improve the survival of newborn animal and human. 2(Li and Bradley, 2011). 2. This type of animal differs from a cloned one because a cloned animal looks exactly identical to the one it has been derived from but not transgenic animals. Future Organ Donors. Drugs can be potentially and immediately harmful to humans, especially during the testing phase of a product, so animal testing allows for researchers to determine the quality and safety of a product before humans take it. , 2006), (Kato et al., 2004), (Hirabayashi et al., 2005). What are the implications of the lack of transparency with regards to industry research in transgenic animals and biopharming? Are there any long term consequences on the environment? Disadvantages of Transgenic Animals: (a) Transgenic animal project is extremely expensive. How has this impacted public perception and political agendas? Hence, they are able to create new cure for specific diseases. There are several methodologies employed in producing transgenic animals. Embryonic stem cell-mediated gene transfer ES cells were first established by two laboratories independently in 1981, Embryonic stem (ES) cells are derived from the inner cell mass of mammalian blastocysts with a great capacity to differentiate into cells of all three germ layers and continuing pluripotency (Evans and Kaufman, 1981; Martin, 1981). Since there are pros of using transgenic animals, it is necessary that you would also know the cons of using these animals. Through animal research, the legality of accidentally causing the death of an animal is very different than what would occur with the accidental death of a human. 1. The British Royal Society has released a statement regarding animal research, noting that almost every 20th century medical achievement relied on the use of animals in some way during the development process. The Pros of Transgenic Animals. Instead of curing diseases via gene therapy, organ transplant it may result in causing more genetic deformities in both animals as well as humans. There are drugs and products that could be harmful to animals, but highly beneficial to humans, and the current state of research priority would make it extremely difficult to know if this was the case. The Cons of Genetically Engineering Animals. On the other hand, more animals are butchered for food every year than are used in animal experimentation, so the ethics of life value are more of a gray area than distinctly black and white. The recombinant ES cells are then combined with new blastocyst which can be attained by either blastocyst injection or morula aggregation. Long before farmers were used selective breeding to enhance economically important trait like growth, milk production, egg production, and etc…consequently, this situation sets the foundation of genetics study that support the study of regulation and function of mammalian genes. Sperm-mediated gene transfer Sperm-mediated gene transfer is ï¬A?rst demonstrated by (Brackett et al., 1971) that mammalian spermatozoa have the inherent capability to bind exogenous DNA. Scientists know much about the animal body and how it works, but they don’t yet know everything. Access to food and water is mandatory, as are shelters that follow minimum sizing standards. 3. (Okada et al.2009) used to introduce lentiviral vector to reduce the possibility of random integration and assessed the feasibility of gene targeting in mouse embryonic stem cells mediated by chronic viral vector. Future Organ Donors. Various markers are used for effective selection of the integrated DNA. It is almost impossible to study certain disease models in humans because of the way a... 3. There are discrepancy in transgenic efï¬A?ciency has been examined among livestock species in success of sperm-mediated gene transfer. Up to 100 million animals, from fish to chimpanzees, may be used every year for the purpose of animal research. Genetic diversity, which is important, in different species it will be no more because of genetic engineering. Committees must approve animal research and be held responsible for the humane treatment of each animal. How do you feel about the process of animal research? , 2002) while in the case of bovine this method had limited achievement to produce transgenic cattle (Schellander et al 1995) therefore, sperm-mediated gene transfer has not been widely adopted for making transgenic animals unlike the other technique. That means animals will likely be sacrificing their lives to determine the safety of a product that a human will never even know was being developed. Create your own unique website with customizable templates. This are some of the application of transgenic technology but it has a huge challenge to apply in concerning the ethical and legality issues from different side religion, animal welfare, food safety, environmental and so on.
