Abstract:

BACKGROUND: The low success rate of dental implants under oxidative stress is one of the problems that needs to be resolved urgently. Human dental pulp stem cells (HDPSCs) have a high potential for multiplication, self-renewal and multidirectional differentiation. HDPSCs have achieved some success in tissue engineering for repairing tissue defects. However, with the in-depth research on oxidative stress, eliminating the adverse effect of oxidative stress on HDPSCs used in tissue engineering becomes urgent.
OBJECTIVE: To review the application progress of HDPSCs in tissue engineering in recent years and to summarize the effects of oxidative stress on HDPSCs.
METHODS: Using “dental pulp stem cells; oxidative stress” as the Chinese and English search terms, we retrieved CNKI and PubMed databases for relevant articles published from January 2001 to December 2017, respectively. After initial screening, 50 eligible articles were further detailed, analyzed and summarized.
RESULTS AND CONCLUSION: HDPSCs have the potential of multiplication, self-renewal and multidirectional differentiation. Immunoregulatory mechanism of HDPSCs is achieved through sub-secreting soluble factors and cytokines and inhibiting the upregulation of T lymphocytes and regulatory T cells, which leads to immune tolerance. Oxidative stress as an important factor affecting cell survival impedes cell proliferation and differentiation via a variety of signal transduction pathways. Current studies on the application of HDPSCs in tissue engineering and regenerative medicine for tissue defect repair are still in its infancy, and there are many problems concerning its regulatory mechanism. Further determination of the oxidative stress mechanism of HDPSCs is warranted.
