Generation of New Neurons in Dorsal Root Ganglia in Adult Rats after Peripheral Nerve Crush Injury

Figure 6

High magnification light microscopy pictures of toluidine blue stained semithin sections of controls (a) and DRG harvested 5 days after nerve crush lesion (b) in which many cells are seen surrounding neurons (b, arrows). A double fluorescence staining shows S100-positive cells (red) surrounding a neurofilament 200 KDa-positive (green) neuron (box in b). The ultrastructural analysis in electron microscopy shows at low magnification morphological features of glial cells (c, d) and neuronal-like cells (e, f, arrows). Scale bars: a, b = 20 µm; c–f = 2 µm.
