A DNA (genetic) marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species.
Scientists from six countries are to begin work on a major new project to identify human genetic variations associated with common diseases, it was announced last week. The US National Institutes of Health (NIH) has secured funding of $100 million over the next three years for the work, which has...
Research published in the journal Science has cast doubt on the versatility of adult stem cells. In experiments to see whether stem cells may be used in potential therapies for neurological and brain diseases such as Alzheimer's or Parkinson's disease, the scientists report that stem cells taken from the bone...
Reporting in the advance online publications section of the science journal Nature, a team of US researchers, led by Catherine Verfaille of the University of Minnesota, has shown that a type of adult stem cell derived from bone marrow (mesenchymal cells) has many of the same characteristics as embryonic stem...
Scientists at the University of Pittsburgh, US, have identified a small section of DNA, a 'genetic marker', which may point to a significantly increased risk of the development of Alzheimer's disease. Ten years was spent studying 300 relatives of 189 people who had developed the disease. It was found that...
