Delayed treatment of spinal cord injury may improve recovery

rotrophin-3 (NT-3), or brain-derived neurotrophic factor (BDNF) for 2 weeks after the transplants were completed.

Differences in motor function between the groups began to emerge 3 to 4 weeks after the transplants. Animals that received a delayed transplant plus treatment with one of the neurotrophins could partially support their weight on their rear legs and had more coordination between the front and back legs than animals that received immediate treatment. After training, about 20 percent of the animals that received transplants plus neurotrophins after a delay were able to consistently support their weight while walking, and another 30 percent were able to do so some of the time. These animals also were able to support themselves on one limb while stepping on stairs. Animals that received immediate treatment with the combined therapy could sometimes support themselves while walking, but less than rats with the delayed treatment. The rats with immediate combined treatment also were unable to support themselves during stair-climbing. Animals that received transplants without neurotrophins could not support themselves during any steps.

When the rats' spinal cords were examined, most (24 of 27) of the animals that received delayed transplants plus neurotrophins had regenerated nerve fibers, or axons, that reached the spinal cord below the transplant. Compared with animals that received immediate treatment, the average axonal growth in animals with delayed treatment was more than 6 times greater in white matter (so called because it contains nerve fibers coated by a whitish substance called myelin) and 2.6 times greater in gray matter, which does not contain myelin. Surprisingly, the axons below the point of injury regrew into the white matter even though previous work has shown that myelin-associated inhibitory factors can interfere with axon growth. The pattern of axon growth was also better in the rats that received delayed treatment, w
