Axonal staining in the injured spinal cord 8 weeks post transplantation. Immunoreactive staining in the control group (a), single injhection (SI) group (b), repeated injections at 3-day intervals (3RI) group (c) and repeated injections at 7-day intervals (7RI) group (d) and quantification (e) of NF-200⁺ fibres in the epicentre of the lesion (****p < 0.0001 versus the other three groups, ^##p < 0.01 versus the control group). Scale bar = 100 μm
