Scientists are putting millions of stem cells for Parkinson's disease into the human brain for the first time.
Scientists discovered that they had introduced stem cells, unspecialized cells that can turn into specialized cells that are able to divide and regenerate permanently in the brain of a man of one. fifty years in Japan.
The procedure was performed last month, a historic step in testing new treatments for Parkinson's disease.
The team hopes that the stem cells will contribute to the growth of parts of the brain damaged by the disease, after experiments on monkeys have shown that they have regained their lost momentum.
Scientists from the Kyoto University have injected men with multi-stranded stem cells (iPS), cells naturally present in the body, more likely in babies and able to switch to one of many other body cells.
The university explained that the state of the man was stable after the operation and that it would be monitored for two years.
The researchers injected 2.4 million stem cells on the left side of the patient 's brain during a process of about three hours.
If you do not notice any problems in the next six months, the team of scientists will plant an additional 2.4 million cells on the right side.
Stem cells derived from healthy donors have been developed to become dopamine-producing brain cells, which do not belong to Parkinson's patients.
The operation took place after the university announced in July that she would conduct the experiment with seven participants aged 50 to 69 years old.
This is the first experience of stem cell transplantation in the brain to treat Parkinson's disease.
Parkinson's disease is a chronic neurodegenerative disease that affects the motor system of the body, often resulting in vibration and other movement difficulties.
According to the Parkinson's Disease Foundation, about 10 million people worldwide suffer from this disease.
