Japanese researchers have succeeded in creating kidney tissue from pluripotent stem cells. This is a world first.
A team of researchers, led by Kenji Osafune of Kyoto University in Japan has developed kidney tissue from induced pluripotent stem cells, in 11 days and with a 90% success rate.
These induced pluripotent stem cells had already talk about them last October. Their discovery by Briton Sir John B. Gurdon and Shinya Yamanaka Japanese had earned the two scientists received the Nobel Prize for Physiology and Medicine in 2012.
Cells that are not derived from human embryos
These are cells made in the laboratory from adult cells that are reprogrammed to become pluripotent, that is to say having the capacity to differentiate into all cell types of the body. In addition, the use of these cells poses no ethical problem because they are not derived from human embryos.
Despite this promising discovery, other steps are required before any medical application. The researchers do not know if the graft of these regenerated cells will, in practice, to cure kidney disease.
However, this research result represents a real hope for those suffering from kidney disease and are sometimes waiting for a kidney transplant.
