Regulation of Pre-Osteoblast Osteogenic Transcription Factors by Different Titanium Surface Topography

Regulation of Pre-Osteoblast Osteogenic Transcription Factors by Different Titanium Surface Topography

Recent topic of discussion on dental implants revolves around differences in titanium surface topography. According to previous studies, different chemical or mechanical processing of titanium surface would elicit diverse cell or tissue reactions. Processes such as sandblasting, acid etching, or the even newer titanium oxide surface, render to excite more osteoblasts than the previous machined ...

Effects of surface nano-topography on human osteoblast filopodia.

Anchorage-dependent cells growing over a substratum require stable adhesion areas on the surface for the next cellular activities. The adhesion is achieved by some contact points called focal adhesions. Because focal adhesions were distributed randomly, a trial to control the positions of focal adhesion with a specific order may cause interesting effects like as cytoskeleton rearrangement, whic...

Investigation on the ordering of titanium oxide nanotubes fabricated by anodization on different substrate surface morphologies

In this study, titanium oxide nanotubes anodized on threedifferent surface morphologies of titanium foils, were investigated. AFM imagesis used to show different surface roughness of these foils. Nanotubes wereanodized on titanium foils with 1) no polishing process (A sample), 2)electropolishing process (B sample) and 3) electropolishing process in ethanolicelectrolyte (C sample). To study the ...

Regulation of endochondral ossification by transcription factors.

Endochondral ossification is very unique and complex biological event which is associated with skeletal development and tissue partnering. Genetic studies and gene-targeting approaches identified several transcription factors that play important roles in endochondral ossification. These transcription factors sequentially and harmoniously regulate each step of endochondral ossification, and cons...
