Stem Cell Therapy Rescues Symptoms of Alzheimer’s Disease

Posted by in categories: biotech/medical, neuroscience

In the study, published August 8, 2023 in Cell Reports, the researchers demonstrate that transplanting hematopoietic stem and progenitor cells was effective in rescuing multiple signs and symptoms of Alzheimer’s in a mouse model of the disease. Mice that received healthy hematopoietic stem cells showed preserved memory and cognition, reduced neuroinflammation and significantly less β-amyloid build-up compared to other Alzheimer’s mice.


Future studies will further explore how the healthy transplanted cells produced such significant improvements, and whether similar transplant strategies can be used to alleviate Alzheimer’s symptoms in humans.

“Alzheimer’s disease poses a major emotional and economic burden on our society, yet there is no effective treatment available,” said Cherqui. “We are excited to see such promising preclinical results from hematopoietic stem cell therapy and look forward to developing a new therapeutic approach for this devastating disease.”

Co-authors of the study include: Alexander Silva, Jay Sharma, Jacqueline Nguyen, Donald P. Pizzo and Debashis Sahoo, all at UC San Diego, as well as Denise Hinz at the La Jolla Institute for Immunology.
