Stem Cells in the News
Embryonic stem cells are master cells found in human embryos that give rise to all the specialised tissues in the body. They have exciting medical potential as a source of replacement tissue for treating disease or injury, though their use is controversial because they involve the destruction of human embryos. The Geron trial, which will begin in the summer, will be the first to test on patients a therapy based on embryonic stem cells. It will investigate the safety and effectiveness of injecting specialised spinal cells grown from the master tissue into people paralysed from the chest down.
