Comparison of the response to spinal cord injury in regenerative and non-regenerative stages. (a) Venn diagram showing all differentially expressed transcripts detected in all time points in R- (green) and NR-stage animals (red). Out of a total of 7,431 transcripts detected in all samples as differentially expressed, 18.9% were differentially regulated in both stages, 29.6% regulated exclusively in the R-stage and 51.5% in the NR-stage. (b, c) Total transcripts that responded differently in R- (b) and NR-stages (c) are depicted as bar graphs. Blue bars, upregulated transcripts; yellow bars, downregulated transcripts.
