Advances in the research of application of dental stem cells in neural tissue engineering

Dental stem cell is a kind of stem cell isolated from dental hard tissue or periodontal tissue, including dental pulp stem cell, stem cell from human exfoliated deciduous teeth, stem cell from root apical papilla, periodontal ligament stem cell, dental follicle progenitor cell, and so on. As seed cell, dental stem cell provides safe and efficient cell source for nerve tissue engineering research. The review aims to introduce the characteristics of these dental stem cells in promoting the regeneration and preparation of nerve and the clinical application.
