The relative release in vitro of endothelin‐1, zinc‐α2‐glycoprotein (ZAG), lipocalin‐2, CD14, RANTES (regulated on activation, normal T cell expressed and secreted protein), lipoprotein lipase (LPL), osteoprotegerin (OPG), fatty acid–binding protein 4 (FABP‐4), visfatin/PBEF/Nampt, glutathione peroxidase‐3 (GPX‐3), intracellular cell adhesion molecule 1 (ICAM‐1), and amyloid A was examined using explants of human adipose tissue as well as the nonfat cell fractions and adipocytes from obese women. Over a 48‐h incubation the majority of the release of LPL was by fat cells whereas that of lipocalin‐2, RANTES, and ICAM‐1 was by the nonfat cells present in human adipose tissue. In contrast appreciable amounts of OPG, amyloid A, ZAG, FABP‐4, GPX‐3, CD14, and visfatin/PBEF/Nampt were released by both fat cells and nonfat cells. There was an excellent correlation ( r = 0.75) between the ratios of adipokine release by fat cells to nonfat cells over 48 h and the ratio of their mRNAs in fat cells to nonfat cells at the start of the incubation. The total release of ZAG, OPG, RANTES, and amyloid A by incubated adipose tissue explants from women with a fat mass of 65 kg was not different from that by women with a fat mass of 29 kg. In contrast that of ICAM‐1, FABP‐4, GPX‐3, visfatin/PBEF/Nampt, CD14, lipocalin‐2, LP, and endothelin‐1 was significantly greater in tissue from women with a total fat mass of 65 kg.
