Diabetes is caused by the cells' inability to respond to insulin, which would normally enable uptake of sugar from the blood. To compensate, the pancreas creates more insulin to clear blood sugar from the circulation. The pancreas becomes exhausted and is unable to produce sufficient insulin to keep up with the demands of the body. This results in the development of type 2 diabetes, which can cause problems such as lack of energy to the cells and, over time, damage to the eyes, kidneys and heart.

The research team, working with the Swedish fast food study group at Linkoping University, also found that weight gain, induced by more than doubling calorie intake through eating 'junk food', causes SPARC levels to increase by 33%. In a further study with the University of Gothenburg, scientists found that a reduced calorie diet can decrease SPARC levels and the stimulus for tissue scarring.

Researchers are now investigating why some people are more prone to fat tissue scarring than others and how further understanding of SPARC could contribute to future treatments for diabetes.
