Abstract:

BACKGROUND: Scientists began to use stem cells to treat Alzheimer’s disease since human beings achieved embryonic stem cells successfully in 1998.
OBJECTIVE: To review the research progress in stem cells treatment for Alzheimer’s disease.
METHODS: An online search of CNKI and PubMed databases was performed for articles published from 1998 to 2012 (CNKI) using key words of “Alzheimer’s disease, stem cells, neural stem cells, mesenchymal stem cells, induced pluripotent stem cells” in Chinese and English, respectively. The articles were included which related to Alzheimer’s disease, neural stem cells, mesenchymal stem cells and induced pluripotent stem cells, and for articles in the same field, those published recently or in authorized journals were selected. A total of 85 articles were searched. According to inclusion and exclusion criteria, 29 were included.
RESULTS AND CONCLUSION: The possible mechanisms of Alzheimer’s disease include differentiation of neural-like cells, secretion of nutrition factor, improvement of endogenous repair, stimulation of vascular regeneration and action on inflammatory cells. This review highlighted research status of neural stem cells, mesenchymal stem cells and induced pluripotent stem cells in the treatment of Alzheimer’s disease. There were advantages and disadvantages for all of them. The low immunogenicity and oncogenicity of neural stem cells are advantages, but limited source reduces their application. Mesenchymal stem cells also have low immunogenicity and oncogenicity, but their differentiation potential is not good as embryonic stem cells. Induced pluripotent stem cells also have many unsolved problems, but they have been regarded as promising stem cells.

Key words: stem cells, neural stem cells, mesenchymal stem cells, brain-derived neurotrophic factor, Alzheimer disease
