Direct Spinal Ventral Root Repair following Avulsion: Effectiveness of a New Heterologous Fibrin Sealant on Motoneuron Survival and Regeneration

Figure 6

(a–d) Representative micrographs of estimated number of myelinated axons in the sciatic nerve, 4 weeks, following ventral root avulsion and repair. (e–h) Representative micrographs of estimated number of myelinated axons in the sciatic nerve, 12 weeks, following ventral root avulsion and repair. Scale bar = 10 μm. (i–l) Frequency distribution of fiber diameter of regenerated fibers, 12 weeks, following ventral root avulsion and repair. (m–p) Frequency distribution of ratio of regenerated fibers, 12 weeks, following ventral root avulsion and repair. ; ; .
