(1) Each IEQ (islet equivalent) represents one islet 150 μm in diameter, (2) Purity is defined by percentage of Dithizone-positive cells (beta cells) in the islet preparations, (3) Viability as measured by live/dead fluorescence, (4) Relative TLR4 mRNA expression levels are variable and this column indicates only presence (Yes) or absence (No) of detectable levels of TLR4 mRNA at any time point, (5) Correlation was obtained from time-course analysis of mRNA expression of TLR4 and β-cell death-associated molecules by the Pearson coefficient test. The presence (Yes) or absence (No) corresponding to a significant positive or negative linear correlation (-0.9 <r > 0.9, p > 0.05) is indicated in this column.
