Invading and resident macrophages were studied in the regenerating rat vagus nerve in vivo and in vitro, using antibodies to invading (EDI) and resident (ED2) macrophages. Fresh vagus nerves contained no EDI positive macrophages as revealed by immunocytochemical staining. In crush lesioned nerves in vivo, the number of EDI positive cells around and distal to the crush lesion, increased dramatically with time. Interestingly, EDI positive cells, although few, appeared in the cultured vagus nerves subjected to a crush lesion. Resident ED2 positive macrophages were abundant in fresh nerves. In vivo, there was a small increase of ED2 positive macrophages at the crush area as regeneration proceeded. In contrast, no increase was observed in vitro and after 3 days no ED2 stained macrophages were found. Immunocytochemical staining for low-affinity NGF-receptors showed a dramatic increase at the crush and distal to it in vivo, while in vitro, the receptors were upregulated along the entire nerve. The results suggest that invading macrophages may not be crucial for the initial and early outgrowth of sensory nerve fibres in peripheral nerves. |
