Artificial Organs Essay

743 words - 3 pages

The science of growing replacement organs and tissues in a lab is called Tissue Engineering. These are created to replace diseased or damaged tissue in the human body. This process begins with a scaffold, a three-dimensional structure, that it utilized to support the cells as they develop and grow. Scientists take the cells to develop an organ specifically from the person in need of the transplant. Once the organ is produced it can be transplanted without the need for immune suppressants since it was developed from the patient's own cells. The organ will not be rejected by the body. From the research I have done, there has been successful human transplants of the bladder, esophagus, trachea, ...view middle of the document...

From what I have read, I believe that the artificially grown organs can permanently replace the original human organs. When it comes to who should be a prime candidate for these types of artificial/synthetic replacements, I think that the rules should be the same for the usual organ transplants. People that subject themselves to illegal drug use or who are alcoholics usually do not get put on donor lists. I think the people who should be in charge of making the judgement calls on who should receive artificial organs should be the same ones that decide on the regular transplants.
I have also found some information on how scientists may have found a way to grow human organs in pigs. They will do this by injecting human stem cells into the embryo of a pig. The organs in which said pig would develop would be human and therefore able to be harvested and transplanted into the patient. So far, this process has been tested by injected stem cells from rats into mice embryos. First, these mice had to be genetically altered so they could grow organs of their own. They could only produce the rat organs. Professor Hiromitsu Nakauchi, the director of the center for stem biology and regenerative...
