FIGURE 3.
Glycosylation of reducible collagen cross-links obtained from MC, EV, and Sh clones at 2 weeks of cell culture. The base hydrolysates of NaB3H4-reduced cells/matrices were analyzed by HPLC. The amounts of GG-, G-, and DHLNL are shown in percentages (GG-DHLNL + G-DHLNL + DHLNL = 100%). Note the decrease in GG-DHLNL with concomitant increase in G-DHLNL in the Sh clones, when compared with controls, MC and EV. No glycosylation was detected for HLNL.
