Scientists from California and Zurich universities have found that the transplant in the brain immediately in the brain can speed up the recovery of damaged sections. The results of the study were published in Nature Communications (Natcom).
Stem cells are cells that are capable of developing different types of cells of the nervous system, including nerve cells and glial cells (brain-supported cells). Researchers have resolved human blood cells and transplant them into damaged parts of the laboratory mice of the brain, one week after ischemic stroke.
Five weeks after the transplant, animals were declining, strengthening blood vessels, partial recovery of connections between neurons and decrease in blood-brain barrier permeability.
Blood-cerebral barrier is a translucent barrier between blood and nervous tissue, which regulates the transportation of materials between the circulation system and the central nervous system. The stroke causes a leak of materials. Blood components that would usually not reach a brain texture, such as proteins, ions and immune cells, invade.
Most of the transplant cells have been turned into Gumragic neurons, cells, which, as early studies have been shown, contribute to the restoration of the brain function after the stroke. Through computer analysis of movements, scientists have also recorded improvement of gait and recovery of fine driving skills in tested animals.
The study is currently underway, scientists are studying the effects of therapy and the possibility of adapting to people for clinical use.
