In the liver tissue of obese animals with type 2 diabetes, unhealthy, fat-filled cells are prolific (small white cells, panel A). After chronic treatment through FGF1 injections, the liver cells successfully lose fat and absorb sugar from the bloodstream (small purple cells, panel B) and more closely resemble cells of normal, non-diabetic animals.
