Lipolytic capacity. Isolated adipocytes from PE and SC fat pads of young (n = 5) and middle-aged (n = 8) rats were incubated in presence or absence of isoproterenol 1 μM for 60 min at 37 °C and the glycerol released in the medium was determined as described. Data in the graph represents the mean ± SEM. Student’s “t” test, unpaired and parametric was used to analyze results. *p < 0.05 (in isoproterenol-stimulated PE adipocytes). Mann-Whitney rank sum test was used to analyze nonparametric data of spontaneous PE results
