As a basis for creating Mature nerve cells became skin cells, says Medical Express, citing a study by researchers at the Salk Institute. The discovery will help better understand the causes of Parkinson's disease, Alzheimer's disease, other diseases of the nervous system.
"This allows us to keep in the cells of the signs associated with aging, so that we can study the impact of age on the brain" - says the results of the research Martin Hetzer, Professor at Salk Institute. In his opinion, the method will help to answer some questions about the work of the human brain and delve into its structure more deeply.
For the experiment, scientists collected skin samples from 19 people. The cells transformed in the laboratory into neurons. It was found that the activity of some genes varied greatly depending on the age of the volunteer, who gave a piece of his skin.
