- Abstract
- Caspase 3 staining in Schwann cells was investigated with immunohistochemistry, as a measure of Schwann cell apoptosis, after transection and immediate (day 0) or delayed rat sciatic nerve repair (30, 90 and 180 days post injury). Cleaved caspase 3 stained Schwann cells significantly increased at the site of lesion (SNL; median [IQR], 15.2 [7.0] %) and in the distal nerve segment (SND; 9.5 [3.6] %) 10 days after immediate repair. The number of cleaved caspase stained Schwann cells also increased significantly after delayed repair, irrespective of length of delay, at both locations (SNL: 22.0-27.1%; SND: 18.5-22.1%; p < 0.05). Some cleaved caspase 3 stained satellite cells were seen in dorsal root ganglia on the injured side, but no... (More)

Cleaved caspase 3 stained Schwann cells significantly increased at the site of lesion (SNL; median [IQR], 15.2 [7.0] %) and in the distal nerve segment (SND; 9.5 [3.6] %) 10 days after immediate repair. The number of cleaved caspase stained Schwann cells also increased significantly after delayed repair, irrespective of length of delay, at both locations (SNL: 22.0-27.1%; SND: 18.5-22.1%; p < 0.05). Some cleaved caspase 3 stained satellite cells were seen in dorsal root ganglia on the injured side, but no stained motor or sensory neurons were observed at any time-point. Delayed nerve repair is associated with more pronounced Schwann cell apoptosis which may explain impaired nerve regeneration after nerve injury and delayed repair. (C) 2009 Elsevier Ireland Ltd.
