• vascular endothelial cells are at low frequency, and that the trans-endothelial pathways are the dominant mechanisms for nanoparticle extravasation in tumors (also called enhanced permeability and retention (EPR) effect) [37]. Since the skin has a denser structure than that of tumor vessels, we speculated

• considered one of the best materials with anticancer properties. Most of the administered NPs that end up in the bloodstream interact with the endothelial layer. The interaction of the NPs with the endothelium widens the existing gaps or induces new ones in the monolayer of vascular endothelial cells, thus

• transcellular route, NPs enter endothelial cells through endocytosis and are transported intracellularly [24][27][28]. Recently, the existence of specific endothelial cells involved in the transport of NPs has been reported [29]. Kingston et al. demonstrated the presence of specific vascular endothelial cells

• in solid tumors that are responsible for the transport of NPs by the transcellular route. They referred to these cells as NP-transporting endothelial cells (N-TECs). Their results suggest that only 21% of tumor vascular endothelial cells, unequally distributed along the blood vessels, participate in

• discusses model studies with a special emphasis on the fabrication of substrates with well-defined nano- and microstructured surfaces for in vitro studies with vascular cells (Figure 1). Vascular endothelial cells (ECs) and smooth muscle cells (SMCs) are two vascular cell types forming blood vessels (Figure

• and regulated by an inner layer of vascular endothelial cells (ECs), and an outer layer of vascular smooth muscle cells (SMCs) (Figure 2) [167][168]. ECs are lining the inner part of the blood vessel (tunica intima), forming the so-called endothelium, and therefore they are in contact with the blood

Likewise, while iron oxide NPs are very helpful with their capability for imaging, their toxicity towards vascular endothelial cells cannot be ignored

Iron oxide NPs also induce inflammation and malfunction in vascular endothelial systems [50]. In the following, we will present assumptions about how the NPs behave in blood

The hypothetical mechanism includes (1) the phosphorylation reaction of claudins, occludins and ZO proteins, (2) the relationship between oxidative stress and the expression level of claudins and occludins, and (3) shear stress (Figure 1).
