Description of Abdominal and Gluteo-femoral Subcutaneous Adipose Tissue Cell Population in Women - GLUTAB

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to compare, in healthy women, the adipose tissue composition between abdomen and thigh and then determine whether differences exist independently of the state of obesity. The findings of this study may help to explain the mechanism contributing to a beneficial role of gluteo-femoral fat contrasting with a deleterious role of abdominal fat on cardiovascular and metabolic dysfunctions.
