FIG. 8.
(a) Correlations between collagen/ww and EY (Pearson r=0.81, p<0.0001) and between collagen/ww and mean value of the average lifetime over the wavelength range of 400/40 nm (Pearson r=0.69, p=0.0015). (b) Correlations between GAG/ww and HA (Pearson r=0.70, p=0.0012) and between GAG/ww and the average lifetime over 400/40 nm (Pearson r=−0.26, p=0.31). (c) Correlations between the average lifetime over 400/40 nm and EY (Pearson r=0.57, p=0.01) and between the average lifetime over 400/40 nm and HA (Pearson r=−0.07, p=0.77). Data of the ribose group were taken out from the correlation test, as ribose did not change the compositions in the cartilage constructs. Color images available online at www.liebertonline.com/tec
