Fig. 3From: Effects of co-incubation of LPS-stimulated RAW 264.7 macrophages on leptin production by 3T3-L1 adipocytes: a method for co-incubating distinct adipose tissue cell linesMean interleukin-6 (IL-6; pg/ml) production for different co-incubation methods of 3T3-L1 + RAW cells (transwells = a; wells = b). IL-6 concentrations for the various co-incubation methods (“treatment”) were compared using a general mixed linear model, followed by post hoc Tukey–Kramer HSD. Data represent least squares means ± SEM of 4 independent experiments. Significant treatment differences are represented with different letters (p < 0.05)Back to article page
