Cellularity of epididymal adipose tissue. Cellularity of epididymal adipose tissue. Coulter counter measurements of adipocyte size and number in fragments of epididymal adipose tissue from B6 (▪) and AKR (□) mice fed either a standard (A) or high-fat diet (B). The mean adipocyte size in mice fed the standard diet was 63 ± 1 and 70 ± 3 μm (P = 0.05) in the B6 and AKR strain, respectively, whereas adipocyte size in animals fed the high-fat diet was 71 ± 2 and 70 ± 2 μm in B6 and AKR, respectively. Bars are means ± SE (n = 4). *P < 0.05 for B6 vs. AKR fed the same diet. Martin Rossmeisl et al. Diabetes 2003;52:1958-1966 ©2003 by American Diabetes Association
