Endometrial stem cells restore brain dopamine levels

Researchers successfully transplanted endometrial stem cells into the brains of mice with a Parkinson-like condition, restoring partially dopamine levels. This finding raises the possibility of women serving as their own stem cell donors and banks being established for men and women with Parkinson's disease.
