Repeated infusion of autologous adipose tissue‐derived stem cells for Parkinson's disease



Mesenchymal stem cells are expected to have a therapeutic effect on progressive neurodegenerative diseases for which there is currently no fundamental treatment.

Aims of the study

The aim is to confirm that repeated infusion of autologous adipose tissue-derived stem cells (ADSCs) can be safely administered to patients with Parkinson’s disease, and to investigate the effects of this as a pilot study.


Three patients with Parkinson’s disease received five or six repeated infusions of ADSCs at intervals of approximately one month. Observations were based on medical examinations by a neurologist and interviews with the patient and caregivers. The severity of Parkinson’s disease was assessed using the Hoehn & Yahr staging scale and Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS).


No adverse events were observed during the observation period from the start of treatment to six months after the end of the last dose. MDS-UPDRS improved in all three patients.


Repeated administration of Autologous ADSCs for Parkinson’s disease was safe and feasible. The results of this pilot study provide insight into the value of further research.
