Bioethical Aspects of Creating Transgenic Animals. Transgenic animals are animals (most commonly mice) that have had a foreign gene deliberately inserted into their genome. Due to the controversial concept of cloning and scientific testing on animals, there are … Xenotransplantation can occur where these transgenic animals can provide patients with replacement livers or hearts or any other organs. Transgenic animals are the genetically modified organisms in which new genes are inserted to see the expression of the proteins. GMOs have emerged as one of the mainstays of biomedical research since the 1980s. Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (or genes) which codes for a particular product such as human protein (a-1-antitrypsin) used to treat emphysema, tissue plasmogen activator (goat), blood clotting factors VIII and IX (sheep) and lactoferrin (cow). GMOs in medicine and research. Transgenic mice are extensively used as animal […] Such animals are most commonly created by the microinjection of DNA into the pronuclei of a fertilised egg which is subsequently implanted into the oviduct of a pseudopregnant surrogate mother. Also Read: Genetically Modified Organisms. Application. Let us have a detailed look at the process, importance and applications of transgenic animals. Does the benefit of biopharming to humans justify the use of animals for this purpose? Economic profits are higher with the production of genetically engineered/transgenic animals for human medicine than for agricultural applications. These animals are developed through different techniques of genetic engineering and have applications in medicine, biotech and pharmaceuticals. The use of farm animals for the production of human pharmaceuticals raises difficult animal welfare issues. The first genetically modified organism was engineered in the year 1980. The medical and biotechnological uses of animal cloning are almost innumerable, as many diseases have been eradicated thanks to the production of these transgenic animals. Application of Biotechnology in Agriculture; Application of Biotechnology in Medicine; Normal Physiology and Development. ADVERTISEMENTS: Read this article to learn about the various applications of transgenic mice. What about products that … Article shared by: . For example, GM animal models of human genetic diseases enabled researchers to test novel therapies and to explore the roles of candidate risk factors and modifiers of disease outcome. Transgenic animals allow us to study how genes affect the normal functions of the body and its development. Transgenic animals in medicine: integration and expression of foreign genes, theoretical and applied aspects. The transgenic animals are genetically engineered and are also known as genetically modified organisms. The following points highlight the top twelve applications of transgenic animals. Commercialization of agricultural applications of transgenic animals is hindered by concerns about the cost and timelines associated with the regulatory process, and by consumer acceptance issues. Medical: An application that is more personable are the medical ones which include xenotransplantation, nutricial supplements and pharmaceuticals. Transgenic Animals: Application # 1: Transgenic animals can be prepared by keeping in view the economically significant traits, such as efficient feed utilization, faster growth rate, production of lean meat, increased production and enhanced immuno-competence. Methods for Producing Transgenic Animals: The main principle in the production of transgenic animals is the introduction of a foreign gene or genes into an animal (the inserted genes are called transgenes).The foreign genes must be transmitted through the germ line, so that every cell, including germ cells, of the animal contains the same modified genetic material 18.

Mouse, although not close to humans in its biology, has been and continues to be the most exploited animal model in trans-genesis experiments. Agriculture applications have a huge effect on humanity. The common feature between man and mouse is that both are mammals.
