Slow sensing ages stem cells
Jennifer Evans | Oct 14, 2008 | 2 min read
Adult stem cells become slower at dividing as they age because they get less efficient at sensing their microenvironment, according to a study to be published in Nature tomorrow. The findings suggest a mechanism to explain why production of adult stem cells such as sperm drops as an organism gets older. "I think this is a fantastic piece of work that begins to explain" how adult stem cells age, said linkurl:Leanne Jones,;http://www-biology.ucsd.edu/faculty/jonesl.html a stem cell biologist at
