- Skinny Mouse Fat Depot Leads To Cell Discovery About Obesity
Obesity is a health problem in western countries in part from an increase in the mass and number of white fat cells. Because white fat cells are post-mitotic, meaning that they cannot divide, scientists have hypothesized that a population of fat precursor ...
