Stem Cell Breakthrough: Replacing Diseased Brain Cells for Healthier Ones

Transplanted healthy glial cells have been found to outcompete and replace diseased or aged brain cells, offering potential for restoring normal brain function and treating neurodegenerative diseases. The study, conducted on humanized mouse brains, demonstrated that healthy glial cells can replace both diseased and aged cells, paving the way for clinical trials on diseases such as Huntington's, ALS, and genetic schizophrenia within the next two years.
