Abstract:

BACKGROUND: Adult neural stem cells are widely distributed in the central nervous system, and have self-renewal and differentiation potential, which can be used as endogenous stem cells to repair injured nerve tissues.
OBJECTIVE: To summarize the research progress of neural stem cells and the microenvironment.
METHODS: The first author searched PubMed (1989/2012) and CNKI (2001/2012) using the key words of “neural stem cells; microenvironment; regulation” in English and Chinese, respectively. 
RESULTS AND CONCLUSION: By screening title and abstract contents, papers with original, reliable and comprehensive analysis were selected, and repetitive research and poor quality articles were excluded. There were 379 English papers and 131 Chinese papers. Finally, only 64 papers were included in result analysis. Adult neural stem cells are closely related to the major cellular components of the microenviroment (vessels, endothelial cells, astrocytes and ependymal cells) and the extracellular matrix in which they are embedded, playing an important role in the regulation of adult neural stem cell survival, proliferation, differentiation. At the same time, the differentiation of adult neural stem cells is regulated by genes. It will produce a new direction of nerve tissue repair between the study of adult neural stem cells and the microenvironment.
