为了评估这些生物材料上的半体形成.

主要方法:

分析了PEEK,ZrO2和Ti的表面特性 (接触角度,粗度).
在材料上培养了口腔角质细胞,以评估代谢活性和半体标志物表达 (整体蛋白α6和β4).
使用ANOVA进行了统计分析.

主要成果:

(Ti) 呈现了较高的氨酸细胞代谢活性.
(ZrO2) 和PEEK的代谢活性较低.
与Ti和PEEK相比,在ZrO2和组织培养聚烯 (TCPS) 上,血胞体标记表达 (整体素α6和β4) 是最高的.

结论:

与ZrO2和PEEK相比,牙角质细胞在Ti上增殖的速度更快.
与Ti和PEEK相比,在ZrO2表面上升调了半体形成标记物.

Desmosomes

Desmosomes

The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein...
