Fig. 8From: Vascular biosafety of commercial hydroxyapatite particles: discrepancy between blood compatibility assays and endothelial cell behaviorGene expression of vWF, CE Cad and CD31 by human endothelial cells exposed to HA particles (a) and CLSM images of cells stained for CD31 (green) and nucleus (red) (b); HA particles: 50 μg/mL. HAp2 decreased the expression of VE Cad and CD31 genes, and affected the immunolabeling of CD31. *Significantly different from control (absence of particles); p ≤ 0.05Back to article page
