Relative gene expression in SCI rats 1 and 7 days after lesion.

Levels of mRNA species quantified by qRT-PCR in the spinal cord of SCI rats 7 days after contusion (solid bars) relative to 1 day expression. The relative expression was calculated from 4 animals using triplicate samples. The samples used were the same as those used for microarray analysis. The relative expression for each gene was calculated with respect to the expression of the housekeeping gene GAPDH. *p<0.01.
