The brain really recover after a stroke, researchers have proved

The brain really recover after a stroke, researchers have proved

Topics: Research, Invention


The University of California introduced a unique gel that allows new neurons and vessels to grow in stroke victims. Its effectiveness was proved by experiments with rodents, reports Medical Express. It turns out, brain tissue can be regenerated in those areas where, it would seem, the cells have long died.

It's no secret that the brain has limited ability to recover from a stroke. And, unlike the liver or skin, it does not regenerate new bonds, blood vessels or tissue structures. If cells die in the brain, this zone is, as it were, isolated and excluded from the general system (a cavity is formed).

Scientists wanted to check whether healthy tissues around the cavity can be included in the process of repairing the damaged area. They injected a special gel into the cavity, which imitated the properties of the brain tissues in density. In fact, a framework was created for the growth of new blood vessels and cells. The gel contained molecules that stimulate vascular growth and suppress inflammation.

In the experiment in mice, cavities in the brain after 16 weeks already contained restored brain tissue, including neural networks. The animals themselves possessed a better body, which indicates the effectiveness of the approach. Eventually, the gel was absorbed by the body, leaving in its place a new healthy tissue.
