Bone marrow generates new neurons in human brains
...one marrow transplants had been performed to treat leukemia
and other non-neurological diseases, and the patients survived from 1 to 9 months after their transplants. The investigators searched the autopsied brain tissue for male cells, which contain a Y chromosome. The Y chromosomes in these cells served a...
Bone marrow cells take on new role in the brain, say Stanford researchers

A subtle tool to study mankind's diseases
