Fig. 1. Hemopexin (Hpx) and Arginase-1 (Arg-1) share similar expression patterns in the mouse spinal cord after SCI.

a, d Relative expression of the Arg-1 and Hpx mRNAs in the mouse spinal cord at the indicated time points post-lesion. b, c, e, f Expression of the Hpx and Arg-1 proteins in the mouse spinal cord post-lesion. *p < 0.05, **p < 0.01 compared with the control mice. N = 24 mice per group, with three mice at each time point. AU arbitrary units. The data are presented as the means ± SEM of three independent experiments
