Molecular mechanisms controlling the development of dopaminergic neurons

Abstract

Dopaminergic (DA) neurons in the midbrain are critically involved in several neurological-psychiatric illnesses and are specifically lost in Parkinson's disease. The DA neurons are generated through the interactions of multiple extrinsic and intrinsic factors during the embryogenesis. The identities and mechanisms of actions of a subset of these factors have recently been elucidated. The same factors have also been successfully used to induce efficient differentiation of DA neurons in vitro from embryonic stem cells or neural progenitors. These advances have far reaching scientific and medical implications. © 2003 Elsevier Science Ltd. All rights reserved.
