Autologous mesenchymal stem cells in chronic stroke

Area of Science:

• Neuroscience
• Regenerative Medicine
• Clinical Trials

Background:

• Cell transplantation shows promise for chronic diseases.
• Mesenchymal stem cells (MSCs) offer potential for stroke recovery.
• This study investigates autologous MSC transplantation in chronic stroke.

Purpose of the Study:

• To evaluate the safety and feasibility of autologous MSC transplantation in chronic stroke patients.
• To assess the efficacy of MSC therapy using clinical scores and functional imaging.
• To explore the potential for functional restoration and neural plasticity post-stroke.

Main Methods:

• Twelve chronic stroke patients meeting specific criteria were recruited.
• Autologous MSCs were administered intravenously, followed by physiotherapy.
• Clinical assessments (FM, mBI, MRC, Ashworth) and imaging (BOLD, DTI) were performed at baseline and 8/24 weeks.
• A control group received physiotherapy only.

Main Results:

• No mortality or adverse reactions were observed in the MSC group.
• Modest improvements in Fugl Meyer (FM) and modified Barthel index (mBI) scores were noted compared to controls.
• Increased activation in Brodmann areas 4 and 6 indicated enhanced neural plasticity.

Conclusions:

• Autologous Mesenchymal Stem Cell (MSC) therapy is safe and feasible for chronic stroke.
• MSC transplantation demonstrated potential for functional improvement and neural plasticity.
• Further randomized controlled trials are necessary to establish definitive efficacy.
