چکیده

The aim of this study was to evaluate the impacts of nano hydroxyapatite (nHA) prepared through Elaeagnus Angustifolia extract (EAE) to expression of immunomodulatory/dentin-pulp regeneration genes in DPSCs. To produce nHA and modified nHA via EAE (nHAEA), the sol-gel technique was used. The functional groups of nanoparticles, morphological, and optical features were determined using FTIR, XRD, SEM, and TEM. The cell viability was then determined using the MTT method in the presence of various EAE, nHA, and nHAEA concentrations. Target gene expression was quantified using a real-time PCR procedure after treating DPSCs with an optimally non-toxic dose of EAE and nanoparticles. The presence of the HA phase was reported with the XRD and FTIR results. According to the results of SEM and TEM, the rod-like NPs could be fabricated. nHAEAs were found to be characterized with low crystallite size, reduced diameter, lengthier, needle-like, and less agglomerated particles compared with nHA. The real-time PCR results demonstrated that nHAEA remarkably increased the expression of human leukocyte antigen-G۵ (HLA-G۵), vascular endothelial growth factor (VEGF), dentin sialophosphoprotein (DSPP), and interleukin۶ (IL۶) genes compared to the nHA group. These findings suggest that nHAEAs might have the potential application in the stemness capability of DPSCs for the treatment of inflamed/damaged pulp.
