Abstract
Polyrotaxane (PR) has garnered increasing attention due to its unique structure and exceptional performance. In this study, a polypseudorotaxane (PPR) initiator was prepared through the self-assembly of bromine-capped Pluronic F68 and β-cyclodextrins (β-CD) in water. Polyrotaxane-containing triblock copolymers (PR copolymers) were successfully synthesized by atom transfer radical polymerization (ATRP) of butyl methacrylate (BMA) using the PPR initiator in the presence of Cu(I)Br/PMDETA. The structure of the PR copolymers was thoroughly characterized using infrared spectroscopy (IR), proton nuclear magnetic resonance (1H NMR), and gel permeation chromatography (GPC). The mobility of β-CD in the PR copolymers was demonstrated through dielectric measurements. Mechanical tests, including tensile strength assessments, thermal mechanical analysis, and dynamic mechanical analysis, confirmed the excellent mechanical properties and good processability of the PR copolymer, attributed to the PBMA blocks. Furthermore, the mechanical properties were found to be modulated by the motility of the threaded β-CDs. Consequently, the superior mechanical properties and the high mobility of the threaded β-CDs suggest promising potential for the as-prepared PR polymer in various advanced applications.

Abstract
Polyrotaxane is a supramolecular assembly consisting of multiple cyclic molecules threaded by a linear polymer. One of the unique properties of polyrotaxane is molecular mobility, cyclic molecules moving along the linear polymer. Molecular mobility of polyrotaxane surfaces affects cell spreading, differentiation, and other cell-related aspects through changing subcellular localization of yes-associated proteins (YAPs). Subcellular YAP localization is also related to cell senescence derived from oxidative stress, which is known to cause cancer, diabetes, and heart disease. Herein, the effects of polyrotaxane surface molecular mobility on subcellular YAP localization and cell senescence following H2 O2 -induced oxidative stress are evaluated in human mesenchymal stem cells (HMSCs) cultured on polyrotaxane surfaces with different molecular mobilities. Oxidative stress promotes cytoplasmic YAP localization in HMSCs on high-mobility polyrotaxane surfaces; however, low-mobility polyrotaxane surfaces more effectively maintain nuclear YAP localization, exhibiting lower senescence-associated β-galactosidase activity and senescence-related gene expression and DNA damage than that seen with the high-mobility surfaces. These results suggest that the molecular mobility of polyrotaxane surfaces regulates subcellular YAP localization, thereby protecting HMSCs from oxidative stress-induced cell senescence. Applying the molecular mobility of polyrotaxane surfaces to implantable scaffolds can provide insights into the prevention and treatment of diseases caused by oxidative stress.

Abstract
Cells can sense the surrounding microenvironmental properties including contact with biomaterials. Although in vitro cell fates in response to the physical properties of cell-adhesive materials have been widely reported, their influence on cell-cell adhesion is unclear. Here, we investigated the role of molecular mobility on polyrotaxane surfaces in epithelial cell-cell adhesion. Polyrotaxane surfaces with high mobility induced cytoplasmic yes-associated protein (YAP) localization in epithelial cells, whereas those with low mobility induced nuclear YAP localization, suggesting that YAP localization is switched by the mobility of the polyrotaxane surface. The cytoplasmic YAP localization increased the expression of tight junction-associated genes. A scratch assay revealed that although the epithelial cells on the low mobile surface rapidly initiated their migration, the cells on the highly mobile surface delayed their migration. Thus, this finding suggests that polyrotaxane surfaces with higher mobility induce cytoplasmic YAP localization, leading to stronger cell-cell adhesion. The polyrotaxane biointerface is promising as a powerful tool to improve the physical immune system and repair biological tissues.

Abstract
Yes-associated protein (YAP), a transcriptional coactivator of the Hippo signaling pathway, has been widely implicated in vascular aging and diseases. For preventing vascular endothelial cell senescence, the design and development of biomaterials to regulate YAP activity are required. This study prepares polyrotaxane-coated surfaces with molecular mobility and clarifies the role of the mobility on vascular endothelial cell senescence through Hippo-YAP signaling. The polyrotaxane surface with high mobility induces cytoplasmic YAP localization in endothelial cells, whereas the surface with low mobility induces nuclear YAP localization. After serial cultivation of endothelial cells using polyrotaxane surfaces with different mobilities for 35 d, the endothelial cells aged on the polyrotaxane surface with high mobility exhibit higher proliferative potential, smaller spreading size, and lower activity of senescence-associated β-galactosidase than those aged on the surface with low mobility. These findings suggest that cellular senescence can be delayed by modulating the molecular mobility on polyrotaxane surfaces.

Abstract
Polyrotaxanes are supramolecular assemblies consisting of cyclic molecules (e.g., α-cyclodextrins) and linear polymer chains (e.g., poly[ethylene glycol]), in which cyclic molecules can move along the polymer chain. Here, we examined the effect of functional groups introduced into the α-cyclodextrins of polyrotaxane on cell responses such as adhesion, proliferation, and differentiation. Polyrotaxane-based triblock copolymers modified with methyl (CH3, hydrophobic, and nonionic), hydroxy (OH, hydrophilic and nonionic), amino (NH2, cationic), and sulfo (SO3H, anionic) groups were coated on the surface of the culture plate to fabricate polyrotaxane surfaces with different surface chemistries. The chemical compositions of each surface were determined via time-of-flight secondary ion mass spectrometry and X-ray photoelectron spectroscopy. The contact angle hysteresis reflecting the molecular mobility and zeta potential of each polyrotaxane surface changed depending on the functional groups. When osteoblast and adipocyte differentiation was induced in human mesenchymal stem cells cultured on each polyrotaxane surface, the cells adhered to the SO3H-modified polyrotaxane surfaces exhibited osteoblast differentiation, whereas the cells adhered to the OH-, NH2-, and SO3H-modified polyrotaxane surfaces preferentially underwent adipocyte differentiation compared with those on the unmodified and CH3-modified polyrotaxane surfaces. Interestingly, the SO3H-modified polyrotaxane surfaces promoted both osteoblast and adipocyte differentiation. High molecular mobility and negative charge on the SO3H-modified polyrotaxane surfaces are expected to contribute to the facilitation of both osteoblast and adipocyte differentiation.

Abstract
Stem cell-based bone tissue engineering is a promising strategy for the treatment of bone defects. Since regeneration of bone tissue takes a long time, promoting osteogenesis of stem cells is desired for earlier recovery from dysfunctions caused by bone defects. Here, we combined endothelial cell co-culture using the molecularly mobile sulfonated polyrotaxane (PRX) surfaces to enhance the mineralization of human bone marrow derived mesenchymal stem cells (HBMSCs). Sulfonated PRXs are composed of sulfopropyl ether-modified α-cyclodextrins (α-CDs) threaded on a polyethylene glycol chain. The molecular mobility of PRX, α-CDs moving along the polymer, can be modulated by the number of α-CDs. When osteoblastic differentiation was induced in HBMSCs and human umbilical vein endothelial cells (HUVECs), co-culture groups on sulfonated PRX surfaces with low molecular mobility showed the highest mineralization, which is about two times as high as co-culture groups on sulfonated PRX surfaces with high molecular mobility. Nuclear accumulation of yes-associated proteins in HBMSCs and cell–cell communication via cytokines or cadherin may play an important role in synergistically induced mineralization of HBMSCs. Molecular mobility of polyrotaxane surfaces promoted mineralization in a co-culture system of mesenchymal stem cells and endothelial cells.![]()

Abstract
The field of tissue engineering and regeneration constantly explores the possibility of utilizing various biomaterials' properties to achieve effective and uneventful tissue repairs. Polyrotaxanes (PRXs) are supramolecular assemblies, which possess interesting mechanical property at a molecular scale termed as molecular mobility. This molecular mobility could be utilized to stimulate various cellular mechanosignaling elements, thereby altering the cellular functions. Apart from this, the versatile nature of PRXs such as the ability to form complex with growth factors and peptides, numerous sites for chemical modifications, and processability into different forms makes them interesting candidates for applications towards tissue engineering. This literature briefly reviews the concepts of PRXs and molecular mobility, the versatile nature of PRXs, and its emerging utility towards certain tissue engineering applications.

Biointerfaces based on polyrotaxane (PRX), consisting of α-cyclodextrins (α-CDs) threaded on a poly(ethylene glycol) (PEG) chain, are promising functionalized platforms for culturing cells. PRXs are characterized by the molecular mobility of constituent molecules where the threading α-CDs can move and rotate along the PEG chain. Taking advantage of this mobility, we have previously succeeded in demonstrating the regulation of cellular responses, such as cellular adhesion, proliferation, and differentiation. In the present study, we investigated differences in the cellular responses to PRX surfaces versus commercially available tissue culture polystyrene (TCPS) surfaces using fibroblasts, preosteoblasts, and preadipocytes. PRX surfaces were found to more significantly promote cellular proliferation than the TCPS surfaces, regardless of the cell type. To identify the signaling pathways involved in the activation of cellular proliferation, a DNA microarray analysis was performed. PRX surfaces showed a significant increase in the integrin-mediated cell adhesion and focal adhesion pathways. Furthermore, PRX surfaces also promoted osteoblast differentiation more than TCPS. These results suggest that structural features of PRX surfaces act as mechanical cues to dominate cellular proliferation and differentiation.
