“We found that if we just transplanted motor neurons into the spinal cord and did nothing else, then the surrounding neighborhood in the spinal cord—the white matter surrounding the spinal fluid, which is full of other, healthy myelinated axons—would see these motor neurons as foreign and reject them,” Kerr says.

In order to coax the nerves to grow out into the paralyzed legs, Kerr had to introduce two last chemicals into his nerve-regenerating cocktail: chemicals that told the myelinated axons that these newly birthed nerves were exactly the same as those that wire the body during fetal development.

Placed along the nerves in the limbs of the body, they tell myelinated axons during development whether to go left or right.

In experiments in lab mice, even very low doses of pleiotrophin, or PTN, significantly enhanced the regeneration of myelinated axons, leading Hoke to hope that PTN may lead to novel treatment options for neurological autoimmune disease.

He had myelinated nerves and a spinal cord and there, within the hard bone box of his skull, he had about a pound and a half of putty-colored aspic: Jesus had a human brain.

Because different parts of the brain are pruned and myelinated at different times, there are biological windows of opportunity when children are interested in and able to learn different skills.
