Cure Mice with Brain Damage Caused by Stroke with Stem Cells.

This is because blocked blood vessels can cause brain damage which, in turn, can be remedied, as researchers at the University of Zurich and the University of Southern California suggest in a new study.

The findings would eventually assist the patients who have suffered some type of stroke to regain their functions.

Stem Cell Injections and Brain Recovery

The researchers used stroke-induced brain damage in mice and discovered that human stem cells injections could develop into immature brain cells successfully. The findings were climactic: the majority of implanted cells have stood in position and acquired the characteristics of complete functioning neurons and have started communicating with other cells.

According to neuroscientist Christian Tackenberg, of the University of Zurich, the stem cells remained alive throughout the entire analysis of five weeks and that majority of them developed into neurons, and in fact even communicated with the existing brain cells.

Additional Findings

Moreover, the researchers noticed that blood vessels self-healed, brain inflammation decreased, and blood-brain barrier strengthened. Even the mice began to demonstrate signs of better movement and coordination, which is also one of the main results of the study because strokes significantly affect the motor control of the body.

The new research is based on the previous research conducted by the same researchers that investigated the best time to inject the stem cells after a stroke. This will be relevant in the formulation of actual treatments: apparently, the brain must be stabilized to some level following the stroke to allow the transplant to be effective.

Comparison with Previous Research

Although previous research has touched on part of the same topic, Tackenberg and colleagues indicate that none of the previous ones delved into the same magnitude as this current one. The researchers did not simply want to see the implanted cells survive, but also whether they would ever develop a neurological connection or not.

According to Tackenberg, our analysis extends much further than other studies that concentrated on the immediate effects immediately after the transplantation.

Impact of Stroke and Future Hopes

Currently, the brain harm that a stroke inflicts is permanent, and it has an impact on a quarter of the population. The brain cells are permanently damaged by the internal bleeding or the oxygen limitation caused by a stroke and may severely impact on speech and movement.

The researchers are optimistic that in the long run stem cell therapy would be in a position to mend what is now beyond repair. In this sector, several inventions are already being seen, such as diabetes and vision loss treatment.

It is yet to be determined whether such an approach would work in human brains, and would require a much longer duration of time to be tested.

Challenges Ahead

The number of challenges in this regard remains numerous: an experiment that could be conducted on the brain may go wrong at any moment. These researchers must come up with means to ensure that the implanted stem cells do not exceed their mandate e.g.

According to Tackenberg, it is necessary to develop new therapeutic techniques to possible brain regeneration following the diseases or accidents.

Our results indicate that as well as new neurons can be produced by neural stem cells, other regeneration processes are also triggered by these.
