Researchers learn how to grow old brain cells using stem cell technology
For the first time, scientists can use skin samples from older patients to create brain cells without rolling back the youthfulness clock in the cells first. The new technique, which yields cells resembling those found in older people's brains, will be a boon to scientists studying age-related diseases like Alzheimer's and Parkinson's.
Mutation in common protein triggers tangles, chaos inside brain cells
Growing human brain cells in lab dishes was key to the findings. Researcher Su-Chun Zhang was the first scientist to convert all-purpose human stem cells into neural cells.
