A. H&E stained lung sections demonstrating improved alveolar structure in hyperoxia exposed rats treated with AMD3100. Original magnification x 100, scale bars: 100 μm.
B. Decreased mean linear intercept (MLI) observed in hyperoxia-AMD3100 treated animals (*p<0.05; RA-PL vs. hyperoxia-PL; **p<0.007, hyperoxia-PL vs. hyperoxia-AMD3100; n=10/group). White bars represent RA animals and black bars represent hyperoxia animals.
C. Increased septal density in hyperoxic-AMD3100 treated rats (*p<0.0001; RA-PL vs. hyperoxia-PL; **p<0.002, hyperoxia-PL vs. hyperoxia-AMD3100; n=10/group).
