With the technology of stem cells, human organs are usually grown using artificial media. Now the process is carried out is no longer in the laboratory, because scientists have succeeded in developing organs of the body of another species, which is animals.
Stem cells are pluripotent cells come from embryos. Stem cells pluripotent with a particular technology can be developed into specific tissue, but may become a body.
In General, the development process of stem conducted in the laboratory in an environment specially conditioned. To create an environment, it is obviously expensive so that it can not be used by everyone.
To overcome this obstacle, scientists successfully takes advantage of the body of an animal as a way for the growth of organs from stem cells of other species. In recent tests, scientists successfully growed pancreas in the body of a mouse.
Prof. Hiromitsu Nakauchi, stem cells from the University of Tokyo expert said that this success, the possibility of growing human organs in the body of an animal becomes largest open. Judging by the similarity of nucleic acid deoxyribo (DNA) structure, which probably used is a pig.
"The ultimate goal of this research is to create human organs." "We have tested successfully 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 to develop organs from stem cells. The first advantage is linked to the shortage of organ donors, resulting in many patients suffering from renal failure who died because they did not immediately get a transplant.
Following is the reaction of the body to release new organs, which has always been a problem in some cases of transplant. In developing organs from their own stem cells, the possibility of rejection by the body is supposed to be much smaller.
