Bone marrow: a possible alternative source of cells in the adult nervous system

Eur J Pharmacol. 2000 Sep 29;405(1-3):297-302. doi: 10.1016/s0014-2999(00)00561-6.


There is increasing evidence that stem cell populations can undergo a transition between mesodermal and neural ectodermal cell fates. Bone marrow-derived cells have been shown to be extremely versatile: they can become brain and liver cells and muscle, while other mesodermal derived cells have been shown to migrate into the brain and differentiate into neurons. Moreover, under the appropriate conditions, neural stem cells can differentiate into hematopoietic and muscle cell fates. It is now well established that newly differentiated cell types are continuously generated from immature stem cells throughout development and in adult mammals, including humans. This review addresses the contribution that bone marrow-derived stem cells may play during neurogenesis. We transplanted male bone marrow into female recipients to track and characterize the Y chromosome containing cells in the CNS (central nervous system) of mice.
