Notably the profiles of the majority of NF + axons, particularly within the rostral and caudal margins of hGDABMP grafted injuries, were end on to the transverse plane of section indicating that, as previously observed for axons within spinal cord injury sites bridged with rodent GDAsBMP [14], these axons were aligned with the normal rostral / caudal trajectory of the DLF white matter (Fig. 2 A and E).

Greater numbers of NF + axons within hGDAsBMP transplants aligned with the normal rostral / caudal trajectory of DLF white matter (E) compared to NF + axons within hGDAsCNTF transplants (F).

Surviving transplants spanned the rostral to caudal extent of injury sites to effectively provide continuous substrates for potential growth of host axons across sites of injury.

Despite the similar ability of transplanted hGDAsBMP and hGDAsCNTF to span the rostral to caudal extent of injury sites and migrate into adjacent tissues, only hGDAsBMP promoted locomotor recovery following transplantation into the transected dorsolateral funiculus (DLF).

For the first row (T) the tail - beat amplitude is − 12, 3, 0, and − 3 mm, for the second row (M) it is − 10, − 1, 3, and − 5 mm, and for the third row (B) it is − 3, − 1, 8, and − 10 mm (measured as the lateral transverse displacement at the caudal fin terminal with respect to the y - axis).
