Transplantation of Umbilical Mesenchymal Stem Cells as a Novel Therapeutic Approach in Alzheimer’s Disease: A Clinical Investigation

Abstract

Alzheimer’s Disease (AD) is a neurodegenerative disorder marked by progressive cognitive impairment and dementia, primarily characterized by the buildup of amyloid-beta plaques and neurofibrillary tangles (NFTs) in the brain. Current treatment strategies offer limited efficacy and do not halt disease progression. This study explored a novel therapeutic approach: the transplantation of umbilical mesenchymal stem cells (UMSCs) in patients with AD.

UMSCs were selected due to their remarkable regenerative potential, low immunogenicity, and ease of procurement. In this clinical investigation, we aimed to evaluate the potential benefits and safety of UMSC transplantation in a group of patients with moderate to severe AD.

Participants were divided into two groups: the control group, receiving standard care, and the treatment group, receiving intravenous UMSC transplantation along with standard care. Both groups underwent positron emission tomography (PET) scans using advanced radiotracers to monitor amyloid-beta plaque and NFT levels. Cognitive function, behavior, and quality of life assessments were carried out at multiple time points post-intervention.

Preliminary results indicated that patients receiving UMSC transplantation demonstrated a reduction in the progression of AD symptoms, improved cognitive performance, and a decrease in the levels of amyloid-beta plaques and NFTs as revealed by PET scans, compared to the control group. The UMSC transplantation was well tolerated, with no significant adverse events reported.

These promising findings suggest that UMSC transplantation could be a potential therapeutic strategy for AD. However, these initial results need to be substantiated by larger, randomized controlled trials. If these findings are confirmed, UMSC transplantation could represent a significant advancement in the treatment of AD, potentially altering disease progression and enhancing patients’ quality of life.
