 L-dopa administration is the most favored andeffective treatment of Parkinson's disease. It re-duces the symptoms (akinesia, rigidity, tremor…), and allows patients to lead an ordinary life. However, when L-dopa treatment is extended over long periods, such as ten years, unfavorable dyskinesia or severe gastrointestinal side effects often appear. In recent years, brain transplantation of dopamine (DA) secreting cells has become one of the promising methods for repairing disturbances in DA metabolism both in basic neuroscience research as well as in clinical practice.

 Brain transplantation experiments had already been performed in the late 19 th century, and became very popular in the 1970's. In the treatment of animal models of Parkinson's disease transplantation of nigral DA cells, adrenal medulla, sympathetic ganglia or PC-12 cells is performed. Adrenal medulla, when transplanted into the eye chamber, chromaffin cells extend processes inside of the graft and innervate the cografted CNS tissue such as cerebral cortex. When grafted in the cerebral ventricle, catecholamine-fluorescent cells survive and extend a limited number of short processes into the caudate.
