Abstract
Stromal vascular cells were isolated from adipose tissue obtained from three different anatomical locations: epididymal (EPI), retroperitoneal (RP), and dorsal subcutaneous (SC), and allowed to differentiate in primary tissue culture. Cell number, protein concentration, glycerophosphate dehydrogenase, and lipoprotein lipase activity were similar in cells obtained from the EPI, RP, and SC regions, as were total insulin binding and the affinity of insulin for its receptor. However, both maximal insulin receptor tyrosine kinase activity and insulin-stimulated phosphorylation of the insulin receptor were significantly lower (P less than 0.05) in cells cultured from the SC region. In addition, newly differentiated adipocytes from the SC region were less sensitive to the ability of insulin to stimulate glucose uptake, and maximal insulin-stimulated glucose uptake by these cells was also significantly lower (P less than 0.05) when compared to cells obtained from the two other regions. Since these studies were performed on adipocyte precursor cells, allowed to differentiate to a similar degree in primary culture, the observed differences in insulin receptor phosphorylating activity, as well as the ability of insulin to stimulate glucose uptake appear to be intrinsic to adipose tissue from the three sites.
