The osteocyte most likely plays a role in bone remodeling by instructing osteoclasts to remove bone at specific sites. This entire process includes recruitment, proliferation and differentiation of osteoclast precursors. And osteocytes are responsible for detecting and responding to mechanical strain and may send signal to other cells. Therefore, to determine the role for osteocytes and mechanical strain in bone remodeling, we examined the effect of steady or pulsatile shear s...

Purpose: The aims of this study were (1) to assess the topographical and chemical changes of Ca and Mg ion implantation procedures using plasma immersion ion implantation and deposition (PIIID) technique and (2) to evaluate cellular response of human bone marrow-derived mesenchymal stem cells (hBMMSCs) to Ca and Mg ion-implanted titanium surface, compared with resorbable blast media (RBM)-treated titanium surface by observing cell attachment, proliferation and gene expression ...

Purpose: To investigate the effect of enamel matrix derivative (Emdogain) on the attachment, growth behavior and the genetic effect of human gingival fibroblasts (HGF) cultured on zirconium disc surfaces.Materials and methods: HGF cells were cultured on i) zirconium discs without enamel matrix derivative (EMD), ii) zirconium discs with EMD 25 μg/ml, and iii) zirconium discs with EMD 100 μg/ml. The cell proliferation activity was evaluated throu...

This study was performed to characterize the effects of calcium phosphate coated and hydroxyapatite coated zirconia compared to smooth surfaced zirconia with bone marrow-derived osteoblast culture.Bone marrow-derived osteoblasts were cultured on i) smooth zirconia, ii) zirconia coated with calcium phosphate (CaP), and iii) zirconia coated with hydroxyapatite (HA). The tetrazolium-based colorimetric assay (MTT test) was used for examining the attachment o...
