Abstract

Abstract This study evaluated the influence of ionic dissolution products of a novel Ca-enriched silicate bioactive glass compared to commercial available hydroxyapaptite samples (Endobonr) on cell activity and vascular endothelial growth factor (VEGF) release in vitro. Bone marrow stromal cells (ST-2) were cultivated with the supernatant of granules of different sizes and at different concentrations (0-1 wt/vol % of granules) for 48 h. In addition to in vitro studies, Ca-ion release from all as cell morphology observation revealed no cytotoxic effect of the released products from all tested materials. It was found that supernatants from granules in concentrations of 1 wt/vol %enhanced the VEGF release from ST2 cells, which is important as a marker of the vascularisation ability of the glass during the bone healing process.

新型富钙硅酸盐生物活性玻璃陶瓷溶解产物对骨髓基质细胞中VEGF释放的影响

摘要本研究评估了一种新型富钙硅酸盐生物活性玻璃的离子溶出产物与市售羟基磷灰石样品（Endobor）相比对体外细胞活性和血管内皮生长因子（VEGF）释放的影响。骨髓基质细胞（ST-2）用不同大小和不同浓度的颗粒上清液（颗粒的0-1wt/vol%）培养48小时。除了体外研究外，细胞形态观察显示所有测试材料释放的产物没有细胞毒性作用。发现来自1wt/vol%浓度的颗粒的上清液增强了ST2细胞的VEGF释放，这在骨愈合过程中作为玻璃的血管形成能力的标志是重要的。
