From: Modulation of inflammatory factors predicts the outcome following spinal cord injury
Polarized macrophages were observed by immunofluorescence following SCI. The number of macrophages in the damaged spinal cord rose dramatically at day 10 (a), day 20 (b), and day 30 (c) after SCI. The M2 subtype of macrophage in the BBB high group is significantly higher than that in the BBB low group from day 10 to day 30 following SCI (d). *P < 0.05, **P < 0.01, as compared with the BBB high group
