Over the past few decades more and more companies have begun to limit the amount of testing they perform on animals; for example, many cosmetic brands now advertise that they do not test on animals right on the bottle. However, animal testing is still a prominent method in the medical field for testing everything from pharmaceuticals to cutting edge therapies, and invasive procedures. Although these testing practices have been conducted for hundreds of years, evidence shows that results from animal models does not always apply to humans. Many studies have found that pre-clinical animal trials do not lead to successful treatments for humans. People who oppose using animals for testing find that the results gathered from animals do not successfully translate to humans effectively enough. In addition, “experimenting on tissues generally requires whole animals or freshly dissected body parts. Such experiments are costly and often unreliable, and can raise ethical issues” (2). There is overwhelming evidence that shows that testing on animals is by far not the best solution, scientists are working hard on new technologies to make animal …show more content…
Human cells and tissues are already being used by many companies to test everything from drugs to cosmetics, “A variety of cell-based tests and tissue models can be used to assess the safety of drugs, chemicals, cosmetics, and consumer products” (3). This technology is not cheap and it is complicated to create and use effectively unless the scientist is trained on the technique. Mainstream use of these chips is not currently feasible, they are expensive, delicate, and difficult to use for inexperienced scientists. In addition to the cost of the product itself, it is also risky to build these chips and then ship them for use because they are so delicate and may not withstand transport. The benefits these chips could bring to society are tremendous, they would enable scientists to be able to test on actual human tissue, all while saving animals from the horrors of animal testing. The hope is that these chips can be a vital component of research and testing in the future, “Organs on chips are still very much a work in progress, but advances in culturing cells and manufacturing nanomaterials mean that they could eventually supplement or supplant animal studies “(2). In addition to using human tissues on chips, more and more testing can be done with computers. Researchers are able to mimic the human system with computer programs and are
