Abstract (original English)

Fat accumulation and the dysfunction of visceral white adipose tissue (WAT), but not subcutaneous WAT, cause abnormalities in whole body metabolic homeostasis. However, no current drugs specifically target visceral WAT. The primary reason for this is that a practical in vitro culture system for mesenteric adipocytes has not been established. To resolve this issue, we sought to identify in vitro adipogenic cells in mesenteric and subcutaneous WATs. First, we examined the expression pattern of surface antigens in stromal-vascular fraction (SVF) cells from mouse mesenteric and subcutaneous WATs, and found the expression of 30 stem cell-related surface antigens. Then, to evaluate the adipogenic ability of each fraction, we performed in vitro screening, and identified five candidate markers for mesenteric adipogenic cells and one candidate marker for subcutaneous adipogenic cells. To investigate whether in vitro adipogenic ability accurately reflects the conditions in vivo, we performed transplantation experiments, and identified CD9(-) CD201(+) Sca-1(-) cells and CD90(+) cells as mesenteric and subcutaneous in vitro adipogenic cells, respectively. Furthermore, mature adipocytes derived from mesenteric and subcutaneous adipogenic cells maintained each characteristic phenotype in vitro. Thus, our study should contribute to the development of a useful culture system for visceral adipo
