Professor Sandrine Thuret, the study’s lead author from King’s IoPPN said, “Previous studies have shown that blood from young mice can have a rejuvenating effect on the cognition of older mice by improving hippocampal neurogenesis. This gave us the idea of modeling the process of neurogenesis in a dish using human brain cells and human blood. In our study, we aimed to use this model to understand the process of neurogenesis and to use changes in this process to predict Alzheimer’s disease and found the first evidence in humans that the body’s circulatory system can have an effect on the brain’s ability to form new cells.”

And the reverse is also true, old blood in young mice will make them older.
Same for organ transplants in humans (and mice). Old organs make young people older.
