“…Crystal surface wettability can influence the interactions between cells and crystals, and crystals with hydrophilic surfaces can promote mineral deposition compared with those with hydrophobic surfaces. When the contact angle (θ) of crystals is less than 90°, crystals are beneficial to cell adhesion, spreading, and proliferation (Nagy et al, ). The adhesion ability of crystals decreases as contact angle increases.…”

The interaction between nanohydroxyapatite (HAP) and smooth muscle cells is an important step in vascular calcification. However, the effect of the shape of HAP on adhesion and endocytosis to aortic smooth muscle cells has been rarely reported. Four different morphological HAP crystals (H-Rod, H-Needle, H-Sphere, and H-Plate) were selected to interact with rat aortic smooth muscle cells (A7R5). Fluorescencelabeled HAP was used to detect crystal adhesion and endocytosis and then pretreated with different endocytic inhibitors to explore the pathway of endocytotic crystals. The distribution of crystals inside and outside the cells and the crystal localization in lysosomes was observed through laser confocal microscopy. The effect of crystal on the cell cycle and the changes in the expression of phosphatidylserine, osteopontin, α-actin, core binding factor alpha 1, and osterix on the surface of A7R5 cells were detected. The adhesion and endocytosis of HAP on A7R5 cells were closely related to crystal shapes and ranked as follows: H-Plate > H-Sphere > H-Needle > H-Rod. H-Sphere and H-Needle were internalized into the cells mainly via the clathrin-mediated pathway, whereas H-Plate and H-Rod were internalized into the cells mainly via macropinocytosis. The endocytosed nano-HAP was mainly distributed in the cell lysosome. The adhesion and endocytosis of HAP to A7R5 cells were positively correlated with the specific surface area, and contact area of HAP and negatively correlated with the absolute value of Zeta and contact angle of HAP. This study provided insights into the effect of crystal morphology on vascular calcification and its mechanism. K E Y W O R D S adhesion, endocytosis, hydroxyapatite, shape, vascular calcification

“…Further, the pinning of a TCL occurs due to the overall roughness created by hydrophilic fibers, leading to the metastable [35] or so-called modified 'Cassie-Baxter' state. The effective contact angle on the rough surface is determined by a small displacement of the contact line (dx), which implies a change in surface energy (dE) [36,37],…”
