How to make stem cells accurately move to the parts of the human body that need to be repaired is a major problem in regenerative medicine research. New technologies can help develop practical methods for treating stroke, brain trauma, and brain lesions.
A press release issued by the University of California, Davis, said that the result was jointly obtained by the school and researchers at Renji Hospital of Shanghai Jiao Tong University. The paper was published in the US Journal of Stem Cell Report.
Researchers have previously discovered that damaged tissue in the body produces a weak electric field that attracts stem cells for repair. Stem cells are carried by the cerebrospinal fluid and, under the guidance of chemical signals, move along the cell movement path called the "head-end migration channel" to the area where the brain is responsible for the sense of smell.
In the new experiment, the researchers transplanted human neural stem cells into the brain of the experimental mouse, placed them on the head-end migration channel, and then applied an electric field to the brain with a safe means. After being affected by the electric field, the stem cells are freed from the influence of chemical signals, moving against the direction of cerebrospinal fluid flow and moving to other areas of the brain.
