“…Several surface modification techniques have been proposed to enhance cell adhesion and retention on grafts, including surface-functionalization such as by ammonia plasma treatment, [7][8][9] pre-coating with adhesive proteins (fibrin, fibronectin, vitronectin, or type I collagen), or with protein sequences prior to cell seeding. [6,10] Improved in vitro cellular adherence and better clinical results are encouraging, and they validate the clinical use of endothelialized grafts; [11] nevertheless, patency of small-diameter synthetic vessels remains a problem, and only sporadic clinical successes with small implants have so far been reported.…”

Low seeding efficiency and poor cell retention under flow-induced shear stress limit the effectiveness of in vitro endothelialization strategies for small-diameter vascular grafts. Primary-amine-rich plasma-polymerized coatings (PPE:N) deposited using low- and atmospheric-pressure plasma discharges on PET and PTFE are evaluated for their ability to improve endothelial cells' kinetics and strength of attachment. PPE:N coatings increase cell adhesion and adhesion rate, spreading, focal adhesion, and resistance to flow-induced shear compared with bare and gelatin-coated PET and PTFE. In particular, about 90% of the cells remain on coated surfaces after 1 h exposure to shear. These coatings, therefore, appear as a promising versatile approach to improve cell seeding strategies for vascular grafts.

“…[30][31][32][33][34] Recently, some researchers have attempted to use an in vitro coculture model of immune cells and ECs to evaluate the inflammatory potential of Figure 4C). Separating the two cell types and treating HUVECs with conditioned media from HANP-exposed THP-1 cells also significantly increased the release of IL-6, indicating that the induction of IL-6 in HUVECs may be largely dependent on the HANP-activated monocytes ( Figure 4C).…”

Potential proinflammatory effects of hydroxyapatite nanoparticles on endothelial cells in a monocyte–endothelial cell coculture model

Currently, synthetic hydroxyapatite nanoparticles (HANPs) are used in nanomedicine fields. The delivery of nanomedicine to the bloodstream exposes the cardiovascular system to a potential threat. However, the possible adverse cardiovascular effects of HANPs remain unclear. Current observations using coculture models of endothelial cells and monocytes with HANPs to mimic the complex physiological functionality of the vascular system demonstrate that monocytes could play an important role in the mechanisms of endothelium dysfunction induced by the exposure to HANPs. Our transmission electron microscopy analysis revealed that both monocytes and endothelial cells could take up HANPs. Moreover, our findings demonstrated that at a subcytotoxic dose, HANPs alone did not cause direct endothelial cell injury, but they did induce an indirect activation of endothelial cells, resulting in increased interleukin-6 production and elevated adhesion molecule expression after coculture with monocytes. The potential proinflammatory effect of HANPs is largely mediated by the release of soluble factors from the activated monocytes, leading to an inflammatory response of the endothelium, which is possibly dependent on p38/c-Jun N-terminal kinase, and nuclear factor-kappa B signaling activation. The use of in vitro monocyte–endothelial cell coculture models for the biocompatibility assessment of HANPs could reveal their potential proinflammatory effects on endothelial cells, suggesting that exposure to HANPs possibly increases the risk of cardiovascular disease.

“…An example application is given in Figure 7 whereby boron nitride nano-tubes (BNNT) were plasma surface treated to modify the BNNT wettability and adhesion characteristics. On account of its benefits, it has extensively been shown that plasma surface treatment can give rise to an enhanced biological cell response [130][131][132][133][134][135][136][137]. Having said this, Arefi-Khonsari et al [138] showed that certain polymers such as octadecyltrichlorosilane self-assembled monolayers (OTS-SAM) are much more resistant to this technique compared to polyethylene (PE), indicating that the successful implementation of this particular technique is material dependent.…”

On account of the recent increase in importance of biological and microbiological adhesion in industries such as healthcare and food manufacturing many researchers are now turning to the study of materials, wettability and adhesion to develop the technology within these industries further. This is highly significant as the stem cell industry alone, for example, is currently worth £3.5 million in the United Kingdom (UK) alone. This paper reviews the current state-of-the-art techniques used for surface treatment with regards to modulating biological adhesion including laser surface treatment, plasma treatment, micro/nano printing and lithography, specifically highlighting areas of interest for further consideration by the scientific community. What is more, this review discusses the advantages and disadvantages of the current techniques enabling the assessment of the most attractive means for modulating biological adhesion, taking in to account cost effectiveness, complexity of equipment and capabilities for processing and analysis.
