Figure 1. CCL28 is upregulated in the spinal cord after SCI. (A, D) qRT-PCR analysis of CCL28 mRNA level (A), ELISA analysis of CCL28 protein concentration (B), and Western blotting analysis of CCL28 protein expression (C) and band intensity analysis of CCL28 (D) in the spinal cord at different time points after sham or SCI surgery (n=5). GAPDH was used as a reference or loading control. Data are mean ± SD. Data were compared with sham group and statistical analysis was performed using Student’s t-test. **, P<0.01; *, P<0.05; NS, not significant.
