How insulin-producing cells show their age

April 6, 2017

Adapted from a Joslin Diabetes Center press release

Diabetes researchers have puzzled for decades about why insulin-producing beta cells in one pancreatic islet often look and behave quite differently than their counterparts in the same islet or in nearby islets. Using newly identified cellular markers of aging, Joslin Diabetes Center scientists now have shown that this diversity may be driven at least in part by differently aged beta cell populations within the pancreas. 

Additionally, the Joslin team demonstrated that the aging of beta cells, with associated losses of their Read more about How insulin-producing cells show their age

A pill to shed fat?

Harvard researchers have created a system using human stem cells to screen for compounds that have the potential to turn white, or “bad,” fat cells into brown, or “good,” fat cells.
