A. Sirius Red staining of human adipose tissue: left: quantified age-adjusted Sirius Red staining, ordinate: Sirius Red staining intensity, arbitrary intensity units (A.U.); *: p<0.005 comparing DM and NDM groups; right: representative Sirius Red-stained VAT from DM, NDM subjects; n=17 DM, 19 NDM subjects for VAT, and n=9 DM, 9 NDM subjects for SAT.
B. Immunohistochemistry for collagens 1, 3, and 6: top: quantified collagen staining intensity in VAT, SAT, ordinate: arbitrary intensity units; *: p<0.050, **: p<0.100 comparing DM and NDM groups; bottom: representative immunohistochemistry images of collagen 1-stained VAT and collagen 3-stained SAT from DM, NDM subjects; n=10 DM, 10 NDM subjects for VAT and SAT.
C. QRTPCR data from VAT, SAT whole tissue RNA; ordinate: fold difference in transcript levels in DM subjects relative to NDM subject group referent=1; *: p<0.050 comparing DM and NDM groups; n=12 DM, 15 NDM subjects for VAT, n=8 DM, 9 NDM subjects for SAT.
D. Linear regression analysis correlating HbA1c (%) with VAT fibrotic transcripts; ordinates: mean fold difference in transcript levels in DM subjects relative to mean transcript level in NDM subject group referent; all correlations with p<0.150 shown.
