A significant correlation (r = 0.4030, r2 = 0.1624, p < 0.01; n = 47) was evident between the concentration of IL6 in participant-derived serum (C 8.2 ± 1.9; OB 6.8 ± 0.6; MetS 10.3 ± 2.4; and T2DM 6.9 ± 0.7 pg/mL) and the proliferative response of ADSCs (Figures 4A,B). This evidence concerns the gene IL6 and type 2 diabetes mellitus.
