Stem cell study opens door to undiscovered world of biology

For the first time, researchers have shown that an essential biological process known as protein synthesis can be studied in adult stem cells -- something scientists have long struggled to accomplish. Many diseases, including degenerative diseases and certain types of cancers, are associated with mutations in the machinery that makes proteins. However, why this is the case has yet to be understood. Discoveries such as this raise the possibility that changes in protein synthesis are necessary for the development of those diseases.
