Scientists Use Body of Pigs to Grow Human Organs
With stem cell technology, human organs are usually grown using artificial media. Now the process is no longer performed in the laboratory, because the scientists succeeded in developing organs in the body of of another species which is animals.
Stem cells are pluripotent cells that are taken from embryos. Pluripotent stem cells with a particular technology not only can be developed into specific tissue, but can become an organ.
Typically, the process of stem cell development conducted in the laboratory in a specially conditioned environment. To create an the environment, of course it is expensive so that it can not be used by everyone.
To overcome this obstacle, scientists successfully takes advantage of an animal’s body as a medium for growing organs from stem cells of other species. In recent trials, scientists successfully growed rat pancreas in the body of a mouse.
Prof. Hiromitsu Nakauchi, stem cell expert from the University of Tokyo said that with this success, the opportunity to grow human organs in the body of an animal is getting more wide open. Judging from the similarity of Deoxyribo Nucleic Acid (DNA) structure, which most likely used is a pig.
“The ultimate goal of this research is to create human organs. We successfully tested in rats and mice, now we are very confident to try it in humans and pigs,” said Prof. Nakauchi, according to the Telegraph.
Prof. Nakauchi said that there are several advantages of developing organs from stem cells. The first advantage is related to the scarcity of donor organs, resulting in many patients with kidney failure who dies because they do not immediately get a transplant.
The next advantage is regarding the body’s reaction to the rejection of new organs, which has always been a problem in some cases of transplantation. By developing organs from their own stem cells, the possibility of rejection by the body is believed to be much smaller.
