Transplanted bone marrow generates new neurons in human brains

Here is a link to a 2002 study that identified neural stem cells that developed in humans after bone marrow transplants.


The study is one of the earliest I have found and was published by: Eva Mezey, Sharon Key, Geogia Vogelsang, Ildiko Szalayova, G. David Lange and Barbara Crain.

The study findings conclude:

"The distribution of the labeled cells was not homogeneous. There were clusters of Y-positive cells, suggesting that single progenitor cells underwent clonal expansion and differentiation. We conclude that adult human bone marrow cells can enter the brain and generate neurons just as rodent cells do. Perhaps this phenomenon could be exploited to prevent the development or progression of neurodegenerative diseases or to repair tissue damaged by infarction or trauma."
