Can scientists rejuvenate an aging brain with a protein found in umbilical cord blood? – Los Angeles Times

What old brains need is a shot of young blood — and the younger the better.

It may sound like a metaphor employed by a randy octogenarian. But new research on mice suggests it can be taken quite literally.

Writing in the journal Nature, Stanford University anti-aging researchers reported Wednesday that they have found a “restorative factor for the aged hippocampus.” It’s a protein called tissue inhibitor of metalloproteinases 2, or TIMP2, that is found in the blood of young humans — and most copiously in umbilical cord blood.

Harvested at the time of an infant’s birth, cord blood is a rich source of many known regenerative substances, including hematopoietic stem cells, the kind found in bone marrow. Cord blood is capable of treating more than 80 diseases, including blood cancers, inherited blood diseases such as sickle cell and thalassemia, and a range of immune deficiencies.
