Abstract (original English)
The purpose of this study was to determine if the antiobesity actions of dehydroepiandrosterone (DHEA) observed in vivo are due to an influence on the proliferation and differentiation of primary cultures of stromal-vascular (SV) cells isolated from human adipose tissue. SV cells were isolated from subcutaneous adipose tissue obtained from a young adult female undergoing elective liposuction. For the proliferation assay (Experiment 1), cultures were fed proliferation media containing 0, 5, 25 or 100 microM DHEA for 3d. At the end of this treatment period, cultures were either prepared for counting or for determining their metabolic activity using the Alamar Blue staining procedure. For the differentiation assays (Experiment 2), cultures were fed differentiation media containing 0, 25 or 50 microM DHEA for 20 d. At the end of this treatment period, cultures were either prepared for lipid staining using Oil Red O or for marker enzyme analysis (glycerol-3-phosphate dehydrogenase activity; GPDH). To determine if the stimulatory effects of DHEA on SV cell differentiation were dependent on the presence of thiazolidinediones (Experiment 3), cultures of differentiating SV cells were incubated in the presence and absence of BRL 49653 and either 0, 25 or 50 microM DHEA. In Experiment 1, cultures treated with 25 and 100 microM DHEA had fewer cells than cultures treated with either 0 or 5
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • This is preclinical work; animal or laboratory results cannot be applied to humans.
