Abstract
This study aimed to evaluate effect of Nano hydroxyapatite coated by Chitosan (NHAP/CS) and bioactive glass nano particulates (nBG) on odontogenic differentiation and proliferation of human dental pulp stem cells (hDPSCs). Methods: hDPSCs were seeded in direct contact with the corresponding Nano-biomaterials in 5 groups: Group (Ι): NHAP (10µg/ml), Group (ΙΙ): NHAP/CS (10µg/ml), Group (ΙΙΙ): nBG (500µg/ml). Group (IV): hDPSCs were cultured with osteogenic medium as a positive control while Group (V): hDPSCs were cultured with Dulbecco's Modified Eagle Medium (DMEM) only as a negative control. Odontogenic differentiation was evaluated based on mineralization related genes .Gene expressions were verified using alkaline phosphatase (ALP) assay and immunofluorescence staining of Dentin matrix protein (DMP-1). Proliferation of cells was evaluated via Trypan Blue staining test and methylthiazol tetrazolium (MTT) assay. Results: All the tested Nano biomaterials exhibited favorable media for odontogenic differentiation and proliferation of hDPSCs. NHAP/CS showed the highest proliferation index via MTT, highest ALP concentration and highest DMP-1Immunofluorescence staining. Conclusions: Compared to pure NHAP and a major biomaterial as nBG, NHAP/CS can induce odontogenic differentiation and proliferation of hDPSCs and could be considered as a good candidate for dentin-pulp regenerative procedures.
