Historical perspective of cell transplantation in Parkinson’s disease

Figure 2 Timeline of the pioneering studies on cell transplantation in animal models of Parkinson’s disease. This timeline shows only a few of the studies performed during the first 10 years of cell grafting in animal models of PD. Most of these studies were selected because they were the first published reports of either the use of a new animal model of PD, a site of grafting, a type of cell or a specific technique. PD: Parkinson’s disease; FVM: Fetal ventral mesencephalic cells; AM: Adrenal medulla.
