A study of 7 candidates with an average age of 42 years suffering from Parkinson’s for an average period of 15 years that received autologous cultured bone marrow stem cells (BMSCs) fibroblast growth factor-2 (FGF2), at a dosage of 1 × 106 cells per kilogram body weight into the sub-lateral ventricular zone, reported that 3 candidates maintained a consistent recovery in their Unified Parkinson’s Disease Rating Scale (UPDRS) “on and off” score. This evidence concerns the gene FGF2 and Parkinson disease.
