Abstract
The remarkable potentiality of bone marrow-derived mesenchymal stem cells (BM-MSCs) after transplantation to models of neurological disease and injury has been described. We have previously published data confirming the influence of BM-MSCs on β-amyloid (Aβ) deposition in an Alzheimer’s disease (AD) mouse model. However, therapeutic approaches in neurological diseases such as AD, including those for BM-MSCs, are increasingly centered on the potential for prophylactic therapy in pro-dromal states where the underlying cause of the disease is apparent but functional deficits are not. In order to investigate whether BM-MSCs could have a beneficial effect in high-risk pre-dementia AD individuals, we treated young AD mice, at an age at which they display neuropathological, but not cognitive features of AD. Following a single intra-cerebral injection of BM-MSCs, interestingly, we found a significant decrease in the cerebral Aβ deposition compared with controls treated with PBS that was sustained up to 2 months post-injection. Expression of dynamin 1 and Synapsin 1, key pre-synaptic proteins associated with synaptic transmission, which are typically decreased in brains of AD patients, were considerably enhanced in the brains of AD mice treated with BM-MSCs and this response was sustained beyond 2 months. These data demonstrate that BM-MSCs produce an acute reduction in Aβ deposits and facilitate changes in key proteins required for synaptic transmission. These findings suggest that BM-MSC transplantation warrants further investigation as a potential therapy for early intervention in pro-dromal AD.

Diagnostic and therapeutic biomarkers of dementia
Dementia affects 18 million people worldwide. Dementia is a syndrome of symptoms caused by brain disease, usually chronic or progressive, clinically characterized by multiple impairments of higher cortical functions such as memory, thinking, orientation, and learning. In addition, in the course of dementia, cognitive deficits are observed, which often hinder ...read more
