Abstract
The development of human tissue models for regenerative medicine and animal-free drug screening requires glycosylated biomaterials such as collagen. An easy and fast biomaterial glycosylation method exploiting Horseradish Peroxidase (HRP) phenol coupling reaction is proposed. The protocol is adaptable to any polymer functionalized with phenol residues or tyrosine containing proteins. As a model the tyrosine residues on collagen films were functionalized with salidroside, a natural β-glucoside with a phenol in the aglycone. Scanning Electron Microscope (SEM) and contact angle analysis revealed the influence of glycosylation on the sample's morphology and wettability. Preliminary biological evaluation showed the cytocompatibility of the glucosylated collagen films.

Abstract
Gelatin sponges are widely employed as hemostatic agents, and are gaining increasing interest as 3D scaffolds for tissue engineering. To broaden their possible application in the field of tissue engineering, a straightforward synthetic protocol able to anchor the disaccharides, maltose and lactose, for specific cell interactions was developed. A high conjugation yield was confirmed by 1H-NMR and FT-IR spectroscopy, and the morphology of the resulting decorated sponges was characterized by SEM. After the crosslinking reaction, the sponges preserve their porous structure as ascertained by SEM. Finally, HepG2 cells cultured on the decorated gelatin sponges show high viability and significant differences in the cellular morphology as a function of the conjugated disaccharide. More spherical morphologies are observed when cultured on maltose-conjugated gelatin sponges, while a more flattened aspect is discerned when cultured onto lactose-conjugated gelatin sponges. Considering the increasing interest in small-sized carbohydrates as signaling cues on biomaterial surfaces, systematic studies on how small carbohydrates might influence cell adhesion and differentiation processes could take advantage of the described protocol.

Abstract
Chitosan is a marine-origin polysaccharide obtained from the deacetylation of chitin, the main component of crustaceans’ exoskeleton, and the second most abundant in nature. Although this biopolymer has received limited attention for several decades right after its discovery, since the new millennium chitosan has emerged owing to its physicochemical, structural and biological properties, multifunctionalities and applications in several sectors. This review aims at providing an overview of chitosan properties, chemical functionalization, and the innovative biomaterials obtained thereof. Firstly, the chemical functionalization of chitosan backbone in the amino and hydroxyl groups will be addressed. Then, the review will focus on the bottom-up strategies to process a wide array of chitosan-based biomaterials. In particular, the preparation of chitosan-based hydrogels, organic–inorganic hybrids, layer-by-layer assemblies, (bio)inks and their use in the biomedical field will be covered aiming to elucidate and inspire the community to keep on exploring the unique features and properties imparted by chitosan to develop advanced biomedical devices. Given the wide body of literature that has appeared in past years, this review is far from being exhaustive. Selected works in the last 10 years will be considered.

Abstract
The development of new advanced constructs resembling structural and functional properties of human organs and tissues requires a deep knowledge of the morphological and biochemical properties of the extracellular matrices (ECM), and the capacity to reproduce them. Manufacturing technologies like 3D printing and bioprinting represent valuable tools for this purpose. This review will describe how morphological and biochemical properties of ECM change in different tissues, organs, healthy and pathological states, and how ECM mimics with the required properties can be generated by 3D printing and bioprinting. The review describes and classifies the polymeric materials of natural and synthetic origin exploited to generate the hydrogels acting as "inks" in the 3D printing process, with particular emphasis on their functionalization allowing crosslinking and conjugation with signaling molecules to develop bio-responsive and bio-instructive ECM mimics.

Abstract
Pathological pain is a prevalent condition that affects majority of adults with a variety of underlying disease conditions. Current available pharmacological pain treatments have several negative and potentially life-threatening side effects associated with their long-term use. Due to the heterogeneity of pain perception and the diversity of neuronal mechanisms that contribute to pain, high-throughput screening of small molecules that may have underlying analgesic properties is essential for identifying new analgesic treatments that are both effective and safe. The F-11 hybrid immortalized cell line is one of the currently available dorsal root ganglion (DRG) cell lines used for drug screening. While F-11 cells are commonly used as analogs to primary DRG sensory neurons, they differ significantly in physiological properties. The present study investigated the impact of differentiation protocols on the expression of mature neuron ion channels and receptors in F-11 cells. Using a customized gene array of more than eighty neuronal ion channels and receptors including voltage-gated ion channels, transient receptor potential channels, and cannabinoid receptors, we assessed the following groups: control F-11 cells; F-11 cells cultured under different culture conditions, and murine DRG tissue. The expression profiles of majority of the investigated ion channels and receptors in F-11 cells were found to be lower compared to primary mouse DRG neurons. F-11 cells cultured under low serum (LSM) conditions had increased expression of several investigated targets including voltage-gated ion channels and cannabinoid receptors when compared to control F-11 cells. The study showed that the culture conditions significantly modulated the transcriptional expression of studied ion channels and receptors, and that long-term culture (21 days) may adversely affect the expression of many of the studied targets.

Abstract
Heating has recently been applied as an alternative to electrical stimulation to modulate excitability and to induce neuritogenesis and the expression of neuronal markers; however, a long-term functional differentiation has not been described so far. Here, we present the results obtained by a new approach for scalable thermal stimulation on the behavior of a model of dorsal root ganglion neurons, the F-11 cell line. Initially, we performed experiments of bulk stimulation in an incubator for different time intervals and temperatures, and significant differences in neurite elongation and in electrophysiological properties were observed in cultures exposed at 41.5 °C for 30 min. Thus, we exposed the cultures to the same temperature increase using a near-infrared laser to irradiate a disc of Prussian blue nanoparticles and poly-vinyl alcohol that we had adhered to the outer surface of the petri dish. In irradiated cells, neurites were significantly longer, and the electrophysiological properties (action potential firing frequency and spontaneous activity) were significantly increased compared to the control. These results show for the first time that a targeted thermal stimulation could induce morphological and functional neuronal differentiation and support the future application of this method as a strategy to modify neuronal behavior in vivo.

Abstract
Traumatic spinal cord injury (SCI) results in disruption of tissue integrity and loss of function. We hypothesize that glycosylation has a role in determining the occurrence of regeneration and that biomaterial treatment can influence this glycosylation response. We investigated the glycosylation response to spinal cord transection in Xenopus laevis and rat. Transected rats received an aligned collagen hydrogel. The response compared regenerative success, regenerative failure, and treatment in an established nonregenerative mammalian system. In a healthy rat spinal cord, ultraperformance liquid chromatography (UPLC) N-glycoprofiling identified complex, hybrid, and oligomannose N-glycans. Following rat SCI, complex and outer-arm fucosylated glycans decreased while oligomannose and hybrid structures increased. Sialic acid was associated with microglia/macrophages following SCI. Treatment with aligned collagen hydrogel had a minimal effect on the glycosylation response. In Xenopus, lectin histochemistry revealed increased levels of N-acetyl-glucosamine (GlcNAc) in premetamorphic animals. The addition of GlcNAc is required for processing complex-type glycans and is a necessary foundation for additional branching. A large increase in sialic acid was observed in nonregenerative animals. This work suggests that glycosylation may influence regenerative success. In particular, loss of complex glycans in rat spinal cord may contribute to regeneration failure. Targeting the glycosylation response may be a promising strategy for future therapies.

Role and therapeutic implications of protein glycosylation in neuroinflammation. Trends Mol Med 2022; 28:270-289.

Abstract
The importance of glycosylation (post-translational attachment of glycan residues to proteins) in the context of neuroinflammation is only now beginning to be understood. Although the glycome is challenging to investigate due to its complexity, this field is gaining interest because of the emergence of novel analytical methods. These investigations offer the possibility of further understanding the molecular signature of disorders with underlying neuroinflammatory cascades. In this review, we portray the clinically relevant trends in glyconeurobiology and suggest glyco-related paths that could be targeted therapeutically to decrease neuroinflammation. A combinatorial insight from glycobiology and neurology can be harnessed to better understand neuroinflammatory-related conditions to identify relevant molecular targets.

Abstract
In lung cancer, CD133+ cells represent the subset of cancer stem cells (CSC) able to sustain tumor growth and metastatic dissemination. CSC function is tightly regulated by specialized niches composed of both stromal cells and extracellular matrix (ECM) proteins, mainly represented by collagen. The relevance of collagen glycosylation, a fundamental post-translational modification controlling several biological processes, in regulating tumor cell phenotype remains, however, largely unexplored. To investigate the bioactive effects of differential ECM glycosylation on lung cancer cells, we prepared collagen films functionalized with glucose (Glc-collagen) and galactose (Gal-collagen) exploiting a neoglycosylation approach based on a reductive amination of maltose and lactose with the amino residues of collagen lysines. We demonstrate that culturing of tumor cells on collagen determines a glycosylation-dependent positive selection of CSC and triggers their expansion/generation. The functional relevance of CD133+ CSC increase was validated in vivo, proving an augmented tumorigenic and metastatic potential. High expression of integrin β1 in its active form is associated with an increased proficiency of tumor cells to sense signaling from glycosylated matrices (glyco-collagen) and to acquire stemness features. Accordingly, inhibition of integrin β1 in tumor cells prevents CSC enrichment, suggesting that binding of integrin β1 to Glc-collagen subtends CSC expansion/generation. We provide evidence suggesting that collagen glycosylation could play an essential role in modulating the creation of a niche favorable for the generation and selection/survival of lung CSC. Interfering with this crosstalk may represent an innovative therapeutic strategy for lung cancer treatment.

Abstract
The regeneration of the nervous system is a challenging task. Currently, regenerative medicine approaches that exploit nature-inspired cues are being studied and hold great promise. The possibility to use protein-based matrices functionalized with small oligo- and monosaccharides is of interest since these can be finely tuned to better mimic the native environment. Collagen has been selected as a promising material that has the potential to be further tailored to incorporate carbohydrates in order to drive cell behavior towards neuroregeneration. Indeed, the grafting of carbohydrates to collagen 2D matrices is proved to enhance its biological significance. In the present study, collagen 2D matrices were grafted with different carbohydrate epitopes, and their potential to drive F-11 neuroblastoma cells towards neuronal differentiation was evaluated. Collagen functionalized with α-glucosides was able to differentiate neuroblastoma cells into functional neurons, while sialyl α-(2→6)-galactosides stimulated cell proliferation.

Abstract
Determination of the adipogenic potential and behavior of adipose-derived mesenchymal stem/stromal cells (ASCs) is particularly relevant for their potential clinical application in regenerative medicine, especially when regeneration is supported by biomaterials or scaffolds. Scaffolds need to be able to induce tissue repair and limit undesired adipogenic differentiation. Depending on the scaffold employed, determination of cell behavior may be hindered by material interference with staining, which will limit either cells identification or dye quantification. Collagen is a promising biomaterial in regenerative medicine, however, histological analysis of cells cultured on collagen-based scaffolds is challenging. Here we describe a new histological method based on iron hematoxylin combined with Oil red O (ORO) staining, for the determination of the adipogenic differentiation of ASCs cultivated on a collagen-based 2D scaffold. ASCs were seeded on collagen films or plastic, differentiated into adipocytes for 14 days, and then stained with either ORO or iron hematoxylin and ORO combined. The collagen films avidly absorbed the ORO dye; conventional staining and quantification by dye extraction failed to discriminate between differentiated and undifferentiated cells on the films. On the contrary, the iron hematoxylin-ORO combination provided a quantitative and more reliable determination of adipocytes based on single cell count. This method is particularly recommended for determining the adipogenic differentiation potential of ASCs and other cell types grown on highly absorptive materials that need to be validated for their potential use in bioengineering and regenerative medicine.

Abstract
Synthetic 3D extracellular matrices (ECMs) find application in cell studies, regenerative medicine, and drug discovery. While cells cultured in a monolayer may exhibit unnatural behavior and develop very different phenotypes and genotypes than in vivo, great efforts in materials chemistry have been devoted to reproducing in vitro behavior in in vivo cell microenvironments. This requires fine-tuning the biochemical and structural actors in synthetic ECMs. This review will present the fundamentals of the ECM, cover the chemical and structural features of the scaffolds used to generate ECM mimics, discuss the nature of the signaling biomolecules required and exploited to generate bioresponsive cell microenvironments able to induce a specific cell fate, and highlight the synthetic strategies involved in creating functional 3D ECM mimics.

Abstract
The brain is one of the softest tissues in the body with storage moduli (G') that range from hundreds to thousands of pascals (Pa) depending upon the anatomic region. Furthermore, pathological processes such as injury, aging and disease can cause subtle changes in the mechanical properties throughout the central nervous system. However, these changes in mechanical properties lie within an extremely narrow range of moduli and there is great interest in understanding their effect on neuron biology. We report here the design of supramolecular hydrogels based on anionic peptide amphiphile nanofibers using oligo-L-lysines of different molecular lengths to precisely tune gel stiffness over the range of interest and found that G' increases by 10.5 Pa for each additional lysine monomer in the oligo-L-lysine chain. We found that small changes in storage modulus on the order of 70 Pa significantly affect survival, neurite growth and tyrosine hydroxylase-positive population in dopaminergic neurons derived from induced pluripotent stem cells. The work reported here offers a strategy to tune mechanical stiffness of hydrogels for use in 3D neuronal cell cultures and transplantation matrices for neural regeneration.

Abstract
Carbohydrates are one of the most powerful and versatile classes of biomolecules that nature
uses to regulate organisms’ biochemistry, modulating plenty of signaling events within cells, triggering
a plethora of physiological and pathological cellular behaviors. In this framework, glycan carrier
systems or carbohydrate-decorated materials constitute interesting and relevant tools for medicinal
chemistry applications. In the last few decades, efforts have been focused, among others, on the development
of multivalent glycoconjugates, biosensors, glycoarrays, carbohydrate-decorated biomaterials
for regenerative medicine, and glyconanoparticles. This review aims to provide the reader with a general
overview of the different carbohydrate carrier systems that have been developed as tools in different
medicinal chemistry approaches relying on carbohydrate-protein interactions. Given the extent of
this topic, the present review will focus on selected examples that highlight the advancements and potentialities
offered by this specific area of research, rather than being an exhaustive literature survey of
any specific glyco-functionalized system.

Abstract
The isolation and culture of dorsal root ganglion (DRG) neurons cause adaptive changes in the expression and regulation of ion channels, with consequences on neuronal excitability. Considering that not all neurons survive the isolation and that DRG neurons are heterogeneous, it is difficult to find the cellular subtype of interest. For this reason, researchers opt for DRG-derived immortal cell lines to investigate endogenous properties. The F-11 cell line is a hybridoma of embryonic rat DRG neurons fused with the mouse neuroblastoma line N18TG2. In the proliferative condition, F-11 cells do not display a gene expression profile correspondent with specific subclasses of sensory neurons, but the most significant differences when compared with DRGs are the reduction of voltage-gated sodium, potassium and calcium channels, and the small amounts of TRPV1 transcripts. To investigate if functional properties of mature F-11 cells showed more similarities with those of isolated DRG neurons, we differentiated them by serum deprivation. Potassium and sodium currents significantly increased with differentiation, and biophysical properties of tetrodotoxin (TTX)-sensitive currents were similar to those characterized in small DRG neurons. The analysis of the voltage-dependence of calcium currents demonstrated the lack of low threshold activated components. The exclusive expression of high threshold activated Ca2+ currents and of TTX-sensitive Na+ currents correlated with the generation of a regular tonic electrical activity, which was recorded in the majority of the cells (80%) and was closely related to the activity of afferent TTX-sensitive A fibers of the proximal urethra and the bladder. Responses to capsaicin and substance P were also recorded in ~20% and ~80% of cells, respectively. The percentage of cells responsive to acetylcholine was consistent with the percentage referred for rat DRG primary neurons and cell electrical activity was modified by activation of non-NMDA receptors as for embryonic DRG neurons. These properties and the algesic profile (responses to pH5 and sensitivity to both ATP and capsaicin), proposed in literature to define a sub-classification of acutely dissociated rat DRG neurons, suggest that differentiated F-11 cells express receptors and ion channels that are also present in sensory neurons.

Abstract
The cell microenvironment plays a pivotal role in mediating cell adhesion, survival, and proliferation in physiological and pathological states. The relevance of extracellular matrix (ECM) proteins in cell fate control is an important issue to take into consideration for both tissue engineering and cell biology studies. The glycosylation of ECM proteins remains, however, largely unexplored. In order to investigate the physio-pathological effects of differential ECM glycosylation, the design of affordable chemoselective methods for ECM components glycosylation is desirable. We will describe a new chemoselective glycosylation approach exploitable in aqueous media and on non-protected substrates, allowing rapid access to glyco-functionalized biomaterials.

Abstract
Glycans have been selected by nature for both structural and 'recognition' purposes. Taking inspiration from nature, nanomedicine exploits glycans not only as structural constituents of nanoparticles and nanostructured biomaterials but also as selective interactors of such glyco-nanotools. Surface glycosylation of nanoparticles finds application in targeting specific cells, whereas recent findings give evidence that the glycan content of cell microenvironment is able to induce the cell fate. This review will highlight the role of glycans in nanomedicine, schematizing the different uses and roles in drug-delivery systems and in biomaterials for regenerative medicine.

Abstract
The conjugation of biomolecules can impart materials with the bioactivity necessary to modulate specific cell behaviors. While the biological roles of particular polypeptide, oligonucleotide, and glycan structures have been extensively reviewed, along with the influence of attachment on material structure and function, the key role played by the conjugation strategy in determining activity is often overlooked. In this review, we focus on the chemistry of biomolecule conjugation and provide a comprehensive overview of the key strategies for achieving controlled biomaterial functionalization. No universal method exists to provide optimal attachment, and here we will discuss both the relative advantages and disadvantages of each technique. In doing so, we highlight the importance of carefully considering the impact and suitability of a particular technique during biomaterial design.

Abstract
The constructs and study of combinatorial libraries of structurally defined homologous extracellular matrix (ECM) glycopeptides can significantly accelerate the identification of cell surface markers involved in a variety of physiological and pathological processes. Herein, we present a simple and reliable host-guest approach to design a high-throughput glyco-collagen library to modulate the primary and secondary cell line migration process. 4-Amidoadamantyl-substituted collagen peptides and β-cyclodextrin appended with mono- or disaccharides were used to construct self-assembled glyco-collagen conjugates (GCCs), which were found to be thermally stable, with triple-helix structures and nanoneedles-like morphologies that altered cell migration processes. We also investigated the glycopeptide's mechanisms of action, which included interactions with integrins and cell signaling kinases. Finally, we report murine wound models to demonstrate the real-time application of GCCs. As a result of our observations, we claim that the host-guest model of ECM glycopeptides offers an effective tool to expedite identification of specific glycopeptides to manipulate cell morphogenesis, cell differentiation metastatic processes, and their biomedical applications.

Abstract
Disease, trauma, and aging account for a significant number of clinical disorders. Regenerative medicine is emerging as a very promising therapeutic option. The design and development of new cell-customised biomaterials able to mimic extracellular matrix (ECM) functionalities represents one of the major strategies to control the cell fate and stimulate tissue regeneration. Recently, hydrogels have received a considerable interest for their use in the modulation and control of cell fate during the regeneration processes. Several synthetic bioresponsive hydrogels are being developed in order to facilitate cell-matrix and cell-cell interactions. In this review, new strategies and future perspectives of such synthetic cell microenvironments will be highlighted.

Abstract
3'-Sialyllactose and 6'-sialyllactose have been covalently linked to collagen films. Preliminary in vitro study on the behavior of mesenchymal stem cells (MSCs) in terms of cell viability, proliferation and induction of osteogenic and chondrogenic related genes has been performed. Results indicate that sialoside epitopes on collagen surface represent a suitable support for MSCs adhesion and cell proliferation, moreover, the neoglycosylation provide MSCs with different and specific stimuli, saccharide-type depending, in term of expression of osteogenic and chondrogenic related genes. In particular, 3'-sialyllactose significantly upregulate the expression of RUNX2 and ALP, well-known markers of osteogenesis, whereas 6'-sialyllactose up-regulate the expression of chondrocyte marker ACAN. Because no osteogenic or chondrogenic supplements in culture media were added, the inductive effect in terms of increased gene expression has to be ascribed uniquely to collagen surface functionalization. These results support the promising role of sialosides in the regulation of stem cells fate and open brilliant perspective for the future use of the presented approach toward osteochondral tissue engineering applications.

Abstract
An artificial aggrecan-like proteoglycan has been designed and synthesized in vitro. At variance with natural proteoglycans, whose glycosaminoglycan chains are always O-linked via a tetrasaccharide bridge to the serine residues of a specific protein core, the present structure consists of chondroitin-6-sulfate chains directly bound to the lysine and hydroxylysine residues of a collagen molecule backbone. The resulting macromolecule has been characterized by histochemistry, atomic force microscopy and FTIR. The number of variables involved (e.g., length and type of the collagen backbone, glycosaminoglycan species, sulfation type and pattern, molecular weight, number and length of side chains, etc.) makes possible to conceive an almost endless variety of artificial proteoglycans, each precisely tailored to a specific functional role. In addition to their use as biomaterials, glycated collagens interact with cells in complex ways and a previous study has already shown the ability of a glycated collagen to redirect fibroblastoma cells from proliferation to differentiation. The research is still underway.
