Abstract
A detailed understanding of the cell adhesion on polymeric surfaces is required to improve the performance of biomaterials. Quartz crystal microbalance with dissipation (QCM-D) as a surface-sensitive technique has the advantage of label-free and real-time monitoring of the cell-polymer interface, providing distinct signal patterns for cell-polymer interactions. In this study, QCM-D was used to monitor human fetal osteoblastic (hFOB) cell adhesion onto polycaprolactone (PCL) and chitosan (CH) homopolymer films as well as their blend films (75:25 and 25:75). Complementary cell culture assays were performed to verify the findings of QCM-D. The thin polymer films were successfully prepared by spin-coating, and relevant properties, i.e., surface morphology, ζ-potential, wettability, film swelling, and fibrinogen adsorption, were characterized. The adsorbed amount of fibrinogen decreased with an increasing percentage of chitosan in the films, which predominantly showed an inverse correlation with surface hydrophilicity. Similarly, the initial cell sedimentation after 1 h resulted in lesser cell deposition as the chitosan ratio increased in the film. Furthermore, the QCM-D signal patterns, which were measured on the homopolymer and blend films during the first 18 h of cell adhesion, also showed an influence of the different interfacial properties. Cells fully spread on pure PCL films and had elongated morphologies as monitored by fluorescence microscopy and scanning electron microscopy (SEM). Corresponding QCM-D signals showed the highest frequency drop and the highest dissipation. Blend films supported cell adhesion but with lower dissipation values than for the PCL film. This could be the result of a higher rigidity of the cell-blend interface because the cells do not pass to the next stages of spreading after secretion of their extracellular matrix (ECM) proteins. Variations in the QCM-D data, which were obtained at the blend films, could be attributed to differences in the morphology of the films. Pure chitosan films showed limited cell adhesion accompanied by low frequency drop and low dissipation.

Abstract
Extracellular vesicles (EVs) are membrane-encapsulated particles secreted by eukaryotic cells that stimulate cell communication and horizontal cargo exchange. EV interactions with stromal cells can result in molecular changes in the recipient cell and, in some cases, lead to disease progression. However, mechanisms leading to these changes are poorly understood. A few model systems are available for studying the outcomes of surface interactions between EV membranes with stromal cells. Here, we created a hybrid supported bilayer incorporating EVs membrane material, called an extracellular vesicle supported bilayer, EVSB. Using EVSBs, we investigated the surface interactions between breast cancer EVs and adipose-derived stem cells (ADSCs) by culturing ADSCs on EVSBs and analyzing cell adhesion, spreading, viability, vascular endothelial growth factor (VEGF) secretion, and myofibroblast differentiation. Results show that cell viability, adhesion, spreading, and proangiogenic activity were enhanced, conditions that promote oncogenic activity, but cell differentiation was not. This model system could be used to develop therapeutic strategies to limit EV-ADSC interactions and proangiogenic conditions. Finally, this model system is not limited to the study of cancer but can be used to study surface interactions between EVs from any origin and any target cell to investigate EV mechanisms leading to cellular changes in other diseases.

Abstract
Sulfated polysaccharides have received much attention in recent years due to their special biological activities, especially the regulation of the biological activity of growth factors such as the representative inductive growth factor recombinant human bone morphogenetic protein-2 (rhBMP-2). However, the regulatory mechanisms from the aspect of the molecular chain structure have rarely been reported. In this article, we selected three kinds of sulfonates containing different backbone structures and functional groups, 2-N,6-O-sulfated chitosan (26 SCS), sulfated dextran (DSS) and poly(sodium-p-styrenesulfonate) (PSS), to explore the interaction between them and rhBMP-2. From in vivo and in vitro osteogenesis-related experiments, 26 SCS showed the best promoting effect on rhBMP-2 induced osteogenic differentiation and the sulfated amino group in 26 SCS could specifically bind to rhBMP-2. These findings indicated that the polysaccharide chain structure was a prerequisite for the synergy effect between 26 SCS and rhBMP-2; the effective combination of -SO3- and rhBMP-2 was an important factor in protecting the bioactivity of rhBMP-2. In addition, the presence of the sulfated amino group was the key factor in the specific binding between 26 SCS and rhBMP-2 and provided the possibility of capturing factors in vivo.

Abstract
Supported lipid bilayers (SLB) functionalized with bioactive molecules can be effectively used to study the interaction of cells with different molecules for fundamental research or to develop biosynthetic systems for various biomedical applications. In this study, RGD and Osteocalcin mimetic (OSN) peptides were used as model molecules for functionalization of otherwise passive SLBs to evaluate cell-surface interactions via real-time monitoring in quartz crystal microbalance with dissipation. Similar platforms were also used in cell culture environment. It was seen that low density of mobile RGD peptides on SLB platforms preserved their biological activity and promoted cell adhesion more efficiently than high number of immobile, physisorbed peptides. Even though nonspecific protein and cell attachment was promoted, cells did not spread well on OSN-coated control surfaces. The stability of SLBs produced with different lipids were evaluated in various medium conditions. Enrichment with different lipids increased the stability of SLB to pure PC bilayer.

Abstract
The involvement of intercellular interactions in various biological events indicates the importance of studying cell-cell interactions using fluid model surfaces. Here, we propose a fluid surface composed of a self-assembled monolayer (SAM) and poly(ethylene glycol)-conjugated phospholipid (PEG-lipid) derivatives, which can be an alternative to supported lipid membranes. The modification of SAM surfaces with PEG-lipids carrying functional peptides resulted in the formation of the fluid surfaces with different mobility, which was quantitatively determined by quartz crystal microbalance with dissipation (QCM-D) and fluorescence recovery after photobleaching (FRAP). Different types of fluid surfaces with calculated diffusion coefficients between 0.9 ± 0.25 and 0.16 ± 0.03 μm2/sec for PEG-lipids derivatives were fabricated, onto which arginylglycylaspartate (RGD) peptides were immobilized for cell adhesion, and compared to solid surfaces with the same surface density of RGD peptides. The fluid surfaces revealed that cell adhesions of epithelial cells (MCF-10 A) and human umbilical vein endothelial cells (HUVEC) could not be established on the surfaces with higher fluidity, while cells could adhere onto surfaces with lower fluidity, where the lateral diffusion of PEG-lipids was approximately 20 times lower, and solid surfaces. Interestingly, cells that adhered onto the surface with lower fluidity proliferated at a normal rate while maintaining their round morphology, which was a different shape from that observed on solid surfaces. Thus, the scaffold fluidity greatly influenced cell adhesion behaviors, demonstrating that it is an important parameter for designing novel biomimetic scaffolds for biomedical applications.

Abstract
Hybrid nanoassemblies of ferritin and silica-supported lipid bilayers (ferritin-SLBs) have been prepared and tested for the adhesion, spreading and proliferation of retinal microvascular endothelial cells (ECs). Lipid membranes with varying surface charge were obtained by mixing cationic 1-palmitoyl-2-oleoyl-sn-glycero-3-ethylphosphocholine (POEPC) with zwitterionic 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) at increasing POPC/POEPC ratios. The supported bilayer formation and their subsequent interaction processes with ferritin were studied at the pH of 7.4 at different protein concentrations, by using the quartz crystal microbalance with dissipation monitoring and by atomic force microscopy. Both kinetics and viscoelastic parameters of the protein-lipid membrane interface were scrutinized, as well as surface coverage. Phase-contrast optical microscopy analyses of the ferritin-SLBs substrates after their interaction with endothelial cells evidenced the highest cell adhesion (2-4h of incubation time) and proliferation (from 24h to 5 days) for the membranes of POPC/POEPC (75:25 ratio). Moreover, ferritin increased both cell adhesion and proliferation in comparison to control glass (respectively 1.5- and 1.75-fold) as well as proliferation in comparison to bare POPC/POEPC (95:5 ratio) (2 fold). Results are very promising in the goal of modulating the endothelial cell response through the interplay of viscoelastic/charge properties of the solid-supported membranes and the SLB-conditioned ferritin activity.
