Repairing Brains

0 106

Researchers have successfully restored mobility and sensation of touch in stroke affected rats. For this reprogrammed human skin cells to were used act like nerve cells. These cells were transplanted into the brains of the rats and allowed to heal. The research was done at Sweden’s Lund University.

The researchers have reprogrammed the human skin cells in the laboratory and then transplanted it into the cerebral cortex of rats. The study gives hope that in future we will be able to replace dead nerve cells with new healthy nerve cells in stroke patients. Studies on how the transplanted cells will affect the opposite hemisphere of the brain is to be done. Also further study on the alteration in brain, quality of life, memory tests and the growth rate of news cells are all required. 

The study was published in the Proceedings of the National Academy of Sciences (PNAS).
