With a single stimulatory molecule, human insulin-producing beta cell replication can be sustained for at least four weeks in a mouse model of diabetes, according to researchers at the University of Pittsburgh School of Medicine in Diabetes, a journal of the American Diabetes Association. They also found several cocktails of molecules that drive human beta cells to replicate, as well as important differences between mouse and human beta cells that could influence how these approaches are best...

Researchers at the University of Pittsburgh School of Medicine, funded by JDRF, have discovered that adult beta cells have the ability to replicate with the help of a protein known as cdk6. This research was led by Andrew F. Stewart, M.D., a Professor of Medicine and Chief of the Division of Endocrinology and Metabolism at the University of Pittsburgh School of Medicine. The complete findings of this discovery can be found in the early online version of Diabetes."Most scientists thought that...

Researchers at the University of Pittsburgh School of Medicine have successfully induced human insulin-producing cells, known as beta cells, to replicate robustly in a living animal, as well as in the lab. The discovery not only could improve models and methods for studying diabetes, but also opens up new possibilities for treating the condition. "Most scientists thought that these important pancreatic cells could not be induced to regenerate, or could only replicate very slowly," explained...
