Tissue Engineering in Replace of Organ Donation - 1353 Words

Organ donation provided a new therapeutic path when new drugs and devices failed to reduce the mortality and morbidity rate of patients with such illnesses as cardiovascular diseases. By replacing damaged organs or tissue with a functioning substitute, organ transplantation offers an immediate cure. Unfortunately, this â€Å"cure† is never guaranteed because of the high risk of graft rejection and that’s if a suitable donor can be found. Thus, tissue engineering has been the projected new treatment for these problems. Tissue engineering replaces the diseased or damaged tissue or organs with biofabricated counterparts made using the specifications dictated by the features of the specific tissue or organ. Tissue engineering is an emerging interdisciplinary field that uses principles from engineering, biology and chemistry in an effort towards tissue regeneration. The main draw of tissue engineering is the regeneration of a patient’s own tissues and organs free from low biofunctionality and poor biocompatibility and serious immune rejection. As medical care continues to improve and life expectancy continues to grow, organ shortages become more problematic.(Manufacturing living things) According to organdonor.gov, a patient is added to the waiting list every 10 minutes and an average of 18 people die everyday waiting for an organ donation. The â€Å"nirvana† of tissue engineering is to replace the need for organ donation altogether. This could be achieved using scaffolding fromShow MoreRelatedThe Field Of Bioartificial Organs1565 Words   |  7 Pagesyears. In this respect, experimentation in the field of bioartificial organs is particularly extraordinary, because it has the potential to kick off a new age in the medical field and science as a whole. However, the research and use of bioartificial organs, specifically the stem cells involved, often stir up controversy. Although the possibilities stem cells bring about are very profitable to the medical field and bioartificial organs, the ethics involved in harvesting the embryos cause debate.

The worldwide demand for organs far surpasses the supply. A study done by the United Network for Organ Sharing in 2004 found that over one hundred thousand patients could have benefited from an organ transplant but only twenty-nine thousand were available. In the United States alone seventeen patients die each and every day while on the waiting list to receive a donor organ. Scientists have been trying toRead MoreHow Scientists Can Most Efficiently Complete Organ Printing Essay2428 Words   |  10 Pagescomplete organ printing. In this lab, the cells will be suspended in a substrate called sodium alginate-collagen, hy drogel, and other reactants. These materials will react to then embed the cells to their goal location. Then, the cells will be able to be fixated into layers. These layers will then come together and form tissues, which according to biological organization will form organs. The inkjet bioprinter allows for this to occur. Tiny ink droplets form a digital design for the organ printingRead MoreThe Potential of Transgenic Organism889 Words   |  4 PagesA Transgenic Organism is an organism that’s genetic material has been transformed using a technique called genetic engineering. This modification contains the mutation, insertion, or deletion of genes. When there is an insertion of genes, they are most commonly from a different species, this is known as horizontal gene transfer. Another way genes can be transferred is in nature, when exogenous DNA (DNA originating outside an organism that has been introduced into the organism) gets through the organismsRead MoreCloning Is The N ew Black2527 Words   |  11 Pagesin research, scientists can possibly create cures for several diseases and create stand in tissues developed from a subject’s body cells (Follow-up). Stem cells are known for their wide variety of uses. Because of this characteristic, scientists can do almost anything with them making them beneficial to medical research. Eventually, scientists hope to manipulate cells into a wide variety of organs and tissues to help treat people with an assortment of illnesses. Once researchers can understand whatRead MoreThe Ethics Of The Field Of Science And Medicine2460 Words   |  10 Pagesdevelopments hinder those values and morals. The field of Bioethics is searching for the line that shouldn’t be crossed by scientific researchers and medical doctors. It also deals with commonly debated issues such as the use of stem cells and genetic engineering practices like cloning. The advancement of technology in the field of science and medicine has a llowed scientists to carry out new procedures like the ones listed above, rather than wonder if they are even possible. But scientific progress doesn’tRead Morekjklk2364 Words   |  10 Pagesoften lack the experience and training—and sometimes the sensitivity—needed to avoid unnecessary animal suffering. The areas of xenotransplantation (transplanting cells, tissues, or organs from one species into another species) and genetic engineering also create a great deal of suffering and death for animals. Genetic engineering consumes and destroys untold volumes of animals in attempts to create animals with specific traits. Nonhuman primates, cats, dogs, mice, rats, and others have all been subjectedRead MoreThe Ethics Of Stem Cells2828 Words   |  12 Pageswhat makes them so of interest to scientists so specific cells can be made to replace damaged cells caused by diseases. There are a couple of sources for getting stem cells; either embryonic stem cells or adult stem cells. In order to get embryonic stem cells scientists can use In Vitro Fertilization or Nuclear Transfer which both have raised ethical concerns while adult stem cells can be retrieved from adult tissue. In Vitro Fertilization is the largest potential source for getting blastocystsRead MoreRobotic Surgery Essay example14445 Words   |  58 Pagesexample, the patient may have a fairly large tumor located in their lungs or stomach. The forced feedback probe would then assist in identifying where the tumor is located and to assure complete ablation with the sole purpose of protecting the healthy tissue (Camarillo, M.S., Krummel, M.D. amp; Salisbury Jr., Ph.D., 2004). As the industry works to continue achievements for scientific drive, there will be more virtual constraints that will be considered as a determining factor.

Surgical robots enable the surgeon to carry out more complex tasks. These surgical robots that are used are not intended to act in place of human surgeons or to replace them but instead these machines act as â€Å"remote extensions that are governed by the surgeon and are best described as master-slave manipulators† (Morris, 2005). The surgeon can use a direct â€Å"telemanipulator which is a remote manipulator that allows
