Scientist found, brains stem cells have capacity to repair damage tissues. This finding may be helpful for the treatment of brain trauma such as stroke. Researchers genetically engineered new born mice to develop in absence of key proteins numb and numb like, and were looking whether stem cells would continue to regenerate without proteins. They found a hole developed in the brain of the mice pups. About four weeks later holes were gone but it is unclear that how cells repaired the damage.
