Multiple Adult Stem Cells May Make Treatment Trickier

Researchers find different types in organs, complicating search for therapeutic cells

(Newser) - There is probably more than one type of adult stem cell in the intestines and other organs, a University of Utah researcher finds—which means therapies based on the cells could be more complicated than expected. Scientists had hoped a single stem cell could fix damage to an entire organ,...

Medicine award recognizes US, British pioneers in gene targeting in mice

(Newser) - The Nobel Prize in medicine was awarded today to three stem-cell researchers who developed techniques for manipulating genes in mice. Mario R. Capecchi,  Martin J. Evans and Oliver Smithies  pioneered a process called gene targeting that allows specific genes to be turned on or off. This in turn allows...
