Abstract (original English)

Upper body obesity is characterized by an expansion of the visceral adipose tissue and is associated with an increased susceptibility for type 2 diabetes and cardiovascular disease. In order to get a better understanding of the regulation of body fat distribution, the aim of the present study was to compare adipocyte development between the omental and subcutaneous adipose tissue region in obese subjects. Therefore, the proliferation and differentiation capacity in primary cultures of adipose tissue-derived stromal cells were compared between the 2 depots in a group of 29 obese individuals, of which 21 were women. Proliferation of the cells was stimulated using fetal calf serum (FCS) and assessed by counting the cell number in the culture dishes. Differentiation of preadipocytes was assessed in parallel by morphological criteria and determination of glycerol-3-phosphate dehydrogenase (GPDH) after stimulation by standardized adipogenic conditions. Stromal cells from the subcutaneous adipose tissue region proliferated faster (doubling time, 4 +/- 1 days) than those from the omental region (doubling time, 5 +/- 1 days), whereas there was no regional difference in adipose differentiation with any of the adipogenic media. The same findings were observed when men were excluded from the analysis. Interestingly, there were more endothelial cells in the cultures from the omental tissue
