Grafting of catecholaminergic cells in the mammalian brain and reconstruction of disturbed function: basic problems to be solved.

Abstract

1. Catecholaminergic cells were grafted in the caudate nucleus of hemi-Parkinsonian model rats, and the following problems were discussed. 2. Phenotypic plasticity and development of catecholamine-producing cells. 3. Mechanism of motor recovery. 4. Trophic factor. 5. Regulation of immunological responses. 6. Long-term survival and security.
