Skin to brain: the promise of adult stem cells

British researchers revealed last week that skin cells can be made to turn into neurones (nerve cells). The research, published in the July 10th edition of The Lancet, adds to the growing list of adult stem cell abilities and may lead to therapies for neurodegenerative diseases such as Parkinson's and Alzheimer's.

The researchers, from the University of Cambridge, collected skin tissue from seven donors aged between 41 and 77. Growing this tissue in the lab, they were able to induce the cells to become neural stem cells using growth hormones, and then serum (blood without the red blood cells). Confirmation that the cells were neural stem cells came by testing for a specific protein called nestin. The research team then coaxed the neural stem cells to become neurones using a brain chemical.

Dr Siddharthen Chandran, who headed the research team, said, 'This study provides a platform for further experimental studies and raises the possibility of generating nerve cells from an individual's own cells, thus overcoming issues of rejection of transplanted nerve cells from other donors'. Using adult stem cells skirts the ethical issues of embryonic stem cells. As well as cell transplants, researchers can use lab-produced neurones to test the efficacy and safety of drugs.

Scientists have discovered adult stem cells in umbilical cord blood that may have the same properties as embryonic stem (ES) cells. Dubbed 'cord-blood-derived embryonic-like stem cells' (CBEs), these cells might have a potential similar to ES cells, offering the possibility of a less controversial way to repair tissue damage from...

Scientists from Newcastle University in the UK are hoping to gain approval for a licence to clone human embryos for stem cell research into diabetes, according to the UK's Observer newspaper. The Human Fertilisation and Embryology Authority (HFEA) is considering the application from the International Centre for Life, having already...

Scientists at the Memorial Sloan-Kettering Cancer Center in New York have successfully used 'therapeutic cloning' to treat mice with the symptoms of Parkinson's disease. The research, which is published in the journal Nature Biotechnology, showed that cells from cloned mouse embryos could alleviate the symptoms of the brain disorder. Team...
