stemceller brings us a story about an experiment that was published online in the journal Cloning & Stem Cells. The paper demonstrated that embryonic stem cells can be used to develop therapeutic cells which will not provoke an immune response from a significant portion of the population. This comes alongside news that UC Irvine researchers have found a method of sorting stem cells that should be "quicker, easier and more cost-effective than current methods." The Cloning & Stem Cells publication states: "It is likely that treatment of large numbers of patients by cell therapy will only be possible if methods are found using any one cell line to treat very large numbers of patients. This very exciting paper represents a significant step forward towards the use of such cells in cell therapy."
