Abstract
Abstract
Nano-hydroxyapatite (nano-HA) has been widely studied as a promising biomaterial because of its potential mechanical and biological properties. In this article, different synthesis methods for nano-HA were summarized. Key factors for the synthesis of nano-HA, including reactant concentration, effects of temperature, PH, additives, aging time, and sintering, were separately investigated. The biological performances of the nano-HA depend strongly on its structures, morphology, and crystallite sizes. Nano-HA with different morphologies may cause different biological effects, such as protein adsorption, cell viability and proliferation, angiogenesis, and vascularization. Recent research progress with respect to the biological functions of the nano-HA in some specific biological applications are summarized and the future development of nano-sized hydroxyapatite is prospected.

Facile Preparation of β-Cyclodextrin-grafted Chitosan Electrospun Nanofibrous Scaffolds as a Hydrophobic Drug Delivery Vehicle for Tissue Engineering Applications. ACS OMEGA 2021; 6:28307-28315.

Abstract
Despite advances in the bio-tissue engineering area, the technical basis to directly load hydrophobic drugs on chitosan (CTS) electrospun nanofibers (ENs) has not yet been fully established. In this study, we fabricated CTS ENs by using an electrospinning (ELSP) system, followed by surface modification using succinyl-beta-cyclodextrin (β-CD) under mild conditions. The β-CD-modified CTS (βCTS) ENs had slightly increased hydrophobicity compared to pristine CTS ENs as well as decreased residual amine content on the surface. Through FTIR spectroscopy and thermogravimetric analysis (TGA), we characterized the surface treatment physiochemically. In the drug release test, we demonstrated the stable and sustained release of a hydrophobic drug (e.g., dexamethasone) loaded on β-CD ENs. During in vitro biocompatibility assessments, the grafting of β-CD was shown to not reduce cell viability compared to pristine CTS ENs. Additionally, cells proliferated well on β-CD ENs, and this was confirmed by F-actin fluorescence staining. Overall, the material and strategies developed in this study have the potential to load a wide array of hydrophobic drugs. This could be applied as a drug carrier for a broad range of tissue engineering applications.

Abstract
Background: Guided tissue regeneration has recently been advocated in re-constructing soft-tissue dimensions in recession defects. Advancement in nanotechnology has led to increased zest for approaches such as electrospinning of biologically active; nanofibrous functionally graded regenerative membranes for periodontal tissue engineering. A functionally graded membrane (FGM) had been tailored by incorporating chitosan and nano-hydroxyapatite over Amnion membrane and used in gingival recession defects. Study Design: It was single-blind, randomized controlled study. Split-mouth study was conducted in nine patients and 22 sites with recession defects were selected. Sites were divided into Group A (Amnion membrane with coronal advanced flap) and Group B (FGM with coronal advanced flap). Materials and Methods: Sites were assessed clinically by recording plaque index (PI), gingival index (GI), vertical recession defect depth (VRDD), relative clinical attachment level (CAL), and width of keratinized tissue at baseline, 3–6 months; and radiographically by recording linear bone growth by dentascan at baseline and 6 months. Result: Both groups showed statistically significant reduction in PI, GI and VRDD, and CAL and nonsignificant reduction in width of keratinized tissue at 3 and 6 months postoperatively. Group A showed statistically significant linear bone growth at 6 months. Group B also showed gain in linear bone growth at 6 months; however, result was statistically nonsignificant. Conclusion: FGM had shown favorable results by enhancing bone growth while preventing the gingival tissue downgrowth.

Abstract
The goal of tissue engineering is to assemble functional constructs that restore, maintain, or improve damaged tissues or organs. Hydrogels formed with natural polymers display high potential in artificial scaffolds for tissue repair as they can resemble the extracellular matrices. Thus, the aim of this study was to design nanocomposite hydrogels of chitosan/oxidized-modified quince seed gum/curcumin-loaded in halloysite nanotubes (CS/OX-QSG/CUR-HNTs) for tissue engineering applications. The produced hydrogels were analyzed for thermal stability, degradation, swelling ratio, gelling time and mechanical properties. The results showed that with increasing content of OX-QSG, thermal stability, swelling ratio, and degradation rate of hydrogels were improved. Notably, the optimal CS/OX-QSG hydrogel with ratio of 25:75 exhibited rapid gelation behavior (<50 s) and improved compressive strength (3.96 ± 0.64 MPa), representing the suitable hydrogel for application in tissue engineering. The MTT test showed that these hydrogels were non-toxic and any reduction or stop of NIH-3 T3 cells growth wasn't observed over time. In addition, CS/OX-QSG 25:75 hydrogels containing CUR-HNTs with 10 and 30% content was significantly (P < 0.05) enhanced cell growth and proliferation (around 150%). Obtained results illustrated that CS/OX-QSG hydrogels with ratio of 25:75 and the content of 30% CUR-HNTs can be an effective scaffold for application in tissue engineering.

Sustained release of epigallocatechin-3-gallate from chitosan-based scaffolds to promote osteogenesis of mesenchymal stem cell. Int J Biol Macromol 2021; 176:96-105.

Abstract
Epigallocatechin-3-gallate (EGCG) is a kind of flavonoids and has the ability to promote differentiation of mesenchymal stem cells (MSCs) into osteoblasts. However, the EGCG is easily metabolized by cells during cell culture, which reduces its bioavailability. Therefore, in this paper, EGCG-loaded chitosan nanoparticles (ECN) were fabricated and entrapped into chitosan/alginate (CS/Alg) scaffolds to form CS/Alg-ECN scaffolds for improving the bioavailability of EGCG. The human umbilical cord mesenchymal stem cells (HUMSCs) were cultured on CS/Alg-ECN scaffolds to induce osteogenic differentiation. The results indicated that the CS/Alg-ECN scaffolds continuously released EGCG for up to 16 days. Besides, these results suggested that CS/Alg-ECN scaffolds promoted osteoblast differentiation through activating Wnt/β-catenin signaling pathway. Collectively, this study demonstrated that the entrapment ECN into CS/Alg scaffolds was a promising strategy for promoting osteogenesis of MSCs.

Abstract
This study was aimed at utilizing polysaccharides for the development of effective hydrogel microparticles for oral insulin delivery that has a controlled, and sustained release to enhance paracellular transcellular absorption. Carboxymethyl β-cyclodextrin grafted carboxymethyl chitosan hydrogels (CMCD-g-CMCs) were prepared from carboxymethyl β-cyclodextrin (CMCD) and carboxymethyl chitosan (CMC) using a water-soluble carbodiimide as a crosslinker in the presence of N-hydroxysuccinimide. After synthesis, the hydrogel structures were determined via FT-IR and XRD analyses. The porous structure of hydrogels was confirmed by SEM observations and swelling behaviours. The insulin release behaviours were found to betriggered by pH in vitro. Results showed that insulin was successfully retained inside the hydrogels in the gastric environment and slowly released following passage to intestinal conditions. The stability of the secondary structure of insulin was studied by dichroism circular (CD) and fluorescence (FL) spectrophotometer measurement. There was no significant difference in the secondary structure between the native and released insulin. In vitro studies revealed that the hydrogel microparticles exhibited non-cytotoxicity and were transported across the Caco-2 cell monolayers mainly via the paracellular pathway. In order to examine the effectiveness of hydrogel-based sustained release microparticles in delivering insulin in vivo, we administered different insulin-loaded hydrogel microparticles to diabetic mice. In these studies, we found that the insulin-loaded hydrogel microparticles provided a significant and sustained (ranging from 6 h to 12 h) reduction in the blood glucose levels of diabetic mice compared with subcutaneous injection. Overall, these findings demonstrate that CMCD-g-CMCs may be a promising protein carrier for use in oral drug delivery.

Abstract
Cyclodextrins are cyclic oligosaccharides, having tyroid shape of the molecule which has a hydrophobic cavity and outer hydrophilic surface. This characteristic feature of the dextrins allows it to function as a functionalizing as well as a stabilizing agent. Polymer nanocomposites are nanoscale composites of polymers with enhanced and synergized properties of its components and have been known to have applications in various fields of chemistry, biomedical, pharmaceutical and environmental purposes to name a few. To impart specificity, thermal, mechanical stability, resistance to solvents and biodegradability to the polymers, cyclodextrins have been incorporated in the nanocomposites. The utilization of the aforementioned properties of cyclodextrins to the polymer nanocomposites, implications of the incorporation of cyclodextrins to polymer nanocomposites and their subsequent applications in various fields have been discussed in this review systematically, using PRISMA guidelines.

Abstract
Tissue engineering approach offers alternative strategies to develop multi-layered/multi-component osteochondral mimetic constructs to meet the requirements of the heterogeneous and layered structure of native osteochondral tissue. Herein, an iterative overlaying process to fabricate a multi-layered scaffold with a gradient composition and layer specific structure have been developed by combining the natural extracellular matrix (ECM) components-chitosan, type I collagen, type II collagen, nanohydroxyapatite- of the osteochondral tissue in biomimetic compositions. Subchondral bone layer was prepared by using freeze-drying method to obtain 3D porous scaffolds. The calcified cartilage and cartilage layers were prepared by thermal gelation method in the hydrogel form. Osteochondral scaffolds fabricated by iterative overlaying of each distinct layer exhibited a porous, continuous gradient structure and supported cell proliferation in a co-culture of MC3T3-E1 preosteoblasts and ATDC5 chondrocytes. Histology and biochemical analysis showed enhanced extracellular matrix production and demonstrated collagen and glycosaminoglycan deposition. Expression of genes specific for bone, calcified cartilage and cartilage were improved in the osteochondral scaffold. Overall, these findings suggest that iterative overlaying of freeze-dried scaffolds and hydrogel matrices prepared by using ECM components in biomimetic ratios to fabricate gradient, multi-layered structures can be a promising strategy without the need for growth factors.

Abstract
The bone-derived-osteoblast seeded biomaterials scaffold in tissue engineering, have displayed prominence in the treatment of the osseous medical condition. In vitro osteogenesis of rabbit osteoblast cell (rOb) from bone tissue (rT) and MSC-derived rOb from bone marrow (rM) on Gelatin-Hydroxyapatite (HG) based biomaterials was investigated. In this work, lyophilized biomaterial was prepared by the addition of amorphous chitosan ('C') to 'H' dispersed in 'G' matrix, to find its role in biomaterials biocompatibility. Isolated rOb seeded biomaterials were studied using CLSM and flow cytometry for proliferation potential. The biomaterial's core and surface morphology was studied from SEM-EDX and AFM respectively. Upon co-culture with HCG, rT over rM showed rabbit bone extracellular matrix (ECM) mimicking properties both in in vitro studies and biomaterials micro architecture. The in vitro metabolic behaviour was studied by Alamar Blue (AB) assay, DNA content using Hoechst 33258, potency via the activity of Alkaline Phosphatase (ALP), Calcium's relative content by Alizarin Red S (ARS) assay. A novel combination of biomaterials-cell interaction was observed when rT was co-cultured with HCG and proved effective in osteogenesis with regard to Bone Bioengineering.

Abstract
Hydroxyapatite (HAP) is a significant bone mineral that establishes bone strength. HAP composites in combination with biodegradable and bioactive polymer poly xylitol sebacic adipate (PXSA) would result in a constant release at target sites. Numerous studies have shown that vitamin K (VK) might possess a vital function in bone metabolism. The purpose of the present study was to inspect the synthesized composite HAP/PXSA/VK in developing polymeric biomaterials composite for the application of bone tissue regeneration. FTIR, X-ray diffraction, SEM and TEM techniques were applied to characterize the prepared composites. The release of VK from the HAP/PXSA/VK composite was evidenced through UV-Vis spectroscopy. In vitro studies proved that the HAP/PXSA/VK composite is appropriate for mesenchymal stem cell culture. Compared to pure HAP prepared following the same method, HAP/PXSA/VK composite provided favourable microstructures and good biodegradation distinctiveness for the application of tissue engineering, as well as tissue in-growth characteristics and improved scaffold cell penetration. This work reveals that the HAP/PXSA/VK composites have the potential for applications in bone tissue engineering.

Abstract
A promising route towards bone tissue engineering is made by the raw materials of the composite which mimics properties of the extracellular matrix components. Herein, the favourable human origin bone cells were seeded on the scaffold types to investigate the best co-culture system. The same has been achieved after the synthesis and characterization of gelatin/hydroxyapatite composites infused with chitosan for their calcium to phosphate (Ca/P) ratio by SEM-EDX. Also, in vitro biodegradation and bio-mineralization determined after immersing in lysozyme and SBF respectively. Uni-axial Compressive Strength (UCS), porosity, qualitative to quantitative phase development by XRD and FTIR were evaluated. The human bone cell-seeded composite was tested by flow cytometry, CLSM, SEM and DSC. This study statistically signified the human mesenchymal stem cell (hM) derived bone cell as potential raw material for minor to severe bone related tissue regenerative studies.

Abstract
Chitin is a linear polysaccharide of N-acetylglucosamine, which is highly abundant in nature and mainly produced by marine crustaceans. Chitosan is obtained by hydrolytic deacetylation. Both polysaccharides are renewable resources, simply and cost-effectively extracted from waste material of fish industry, mainly crab and shrimp shells. Research over the past five decades has revealed that chitosan, in particular, possesses unique and useful characteristics such as chemical versatility, polyelectrolyte properties, gel- and film-forming ability, high adsorption capacity, antimicrobial and antioxidative properties, low toxicity, and biocompatibility and biodegradability features. A plethora of chemical chitosan derivatives have been synthesized yielding improved materials with suggested or effective applications in water treatment, biosensor engineering, agriculture, food processing and storage, textile additives, cosmetics fabrication, and in veterinary and human medicine. The number of studies in this research field has exploded particularly during the last two decades. Here, we review recent advances in utilizing chitosan and chitosan derivatives in different technical, agricultural, and biomedical fields.

Abstract
Microparticles (MPs) exhibit fast dissolution, characterized by a burst drug release pattern. In the present work, we prepared core-shell MPs of simvastatin (SIM) and zein with chitosan (CS) and nano-hydroxyapatite (nHA) as a drug carrier using the coaxial electrospray deposition method. The morphology, formation and in vitro osteogenic differentiation of these MPs were studied. The synthetic MPs have a diameter of about 1 μm and they are composed of non-toxic natural materials. They provide an effective way to enable long-term sustained-release activity, which is controlled by their double layer structures. The CS-nHA/zein-SIM MPs presented a low initial burst release (approximately 35-47%) within the first 24 h of application followed by the sustained release for at least 4 weeks. In vitro cell culture experiments were performed and the results revealed that the CS-nHA/zein-SIM core-shell MPs were beneficial to the adhesion, proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). The CS-nHA/zein-SIM MPs with a low SIM concentration were beneficial to cell proliferation and promotion of osteogenic differentiation.

Abstract
A range of traditional and free-form fabrication technologies have been investigated and, in numerous occasions, commercialized for use in the field of regenerative tissue engineering (TE). The demand for technologies capable of treating bone defects inherently difficult to repair has been on the rise. This quest, accompanied by the advent of functionally tailored, biocompatible, and biodegradable materials, has garnered an enormous research interest in bone TE. As a result, different materials and fabrication methods have been investigated towards this end, leading to a deeper understanding of the geometrical, mechanical and biological requirements associated with bone scaffolds. As our understanding of the scaffold requirements expands, so do the capability requirements of the fabrication processes. The goal of this review is to provide a broad examination of existing scaffold fabrication processes and highlight future trends in their development. To appreciate the clinical requirements of bone scaffolds, a brief review of the biological process by which bone regenerates itself is presented first. This is followed by a summary and comparisons of commonly used implant techniques to highlight the advantages of TE-based approaches over traditional grafting methods. A detailed discussion on the clinical and mechanical requirements of bone scaffolds then follows. The remainder of the manuscript is dedicated to current scaffold fabrication methods, their unique capabilities and perceived shortcomings. The range of biomaterials employed in each fabrication method is summarized. Selected traditional and non-traditional fabrication methods are discussed with a highlight on their future potential from the authors' perspective. This study is motivated by the rapidly growing demand for effective scaffold fabrication processes capable of economically producing constructs with intricate and precisely controlled internal and external architectures. STATEMENT OF SIGNIFICANCE: The manuscript summarizes the current state of fabrication technologies and materials used for creating scaffolds in bone tissue engineering applications. A comprehensive analysis of different fabrication methods (traditional and free-form) were summarized in this review paper, with emphasis on recent developments in the field. The fabrication techniques suitable for creating scaffolds for tissue engineering was particularly targeted and their use in bone tissue engineering were articulated. Along with the fabrication techniques, we emphasized the choice of materials in these processes. Considering the limitations of each process, we highlighted the materials and the material properties critical in that particular process and provided a brief rational for the choice of the materials. The functional performance for bone tissue engineering are summarized for different fabrication processes and the choice of biomaterials. Finally, we provide a perspective on the future of the field, highlighting the knowledge gaps and promising avenues in pursuit of effective scaffolds for bone tissue engineering. This extensive review of the field will provide research community with a reference source for current approaches to scaffold preparation. We hope to encourage the researchers to generate next generation biomaterials to be used in these fabrication processes. By providing both advantages and disadvantage of each fabrication method in detail, new fabrication techniques might be devised that will overcome the limitations of the current approaches. These studies should facilitate the efforts of researchers interested in generating ideal scaffolds, and should have applications beyond the repair of bone tissue.

Abstract
Nano-hydroxyapatite was incorporated into polymer matrix of Dextran/Chitosan to achieve a novel composite scaffold by freeze drying technique. The synthesized composite scaffolds were recognized by different performances such as: X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and Scanning electron microscope (SEM). The results revealed the complex formation between dextran and chitosan with an excellent dispersion of nHA inside the polymer matrix. The SEM images showed the presence of interconnected pore structure inside the scaffolds. The porosity of the composites was found to decrease from 82% to 67% by adding nanohydroxyapatite to the polymer matrix of Dextran/Chitosan. The mechanical properties of the scaffolds were measured by compression test. The obtained results verified that the presence of nHA can noticeably enhance young’s modulus and compressive strength of the composite scaffolds. All the obtained results essentially recommend that these composites can be a good candidate for bone tissue engineering applications.

Abstract
Tissue engineering approaches combine a bioscaffold with stem cells to provide biological substitutes that can repair bone defects and eventually improve tissue functions. The prospective bioscaffold should have good osteoinductivity. Surface chemical and roughness modifications are regarded as valuable strategies for developing bioscaffolds because of their positive effects on enhancing osteogenic differentiation. However, the synergistic combination of the two strategies is currently poorly studied. In this work, a nanoengineered scaffold with surface chemistry (oxygen-containing groups) and roughness (Rq = 74.1 nm) modifications was fabricated by doping nanohydroxyapatite (nHA), chemically crosslinked graphene oxide (GO) and carboxymethyl chitosan (CMC). The biocompatibility and osteoinductivity of the nanoengineered CMC/nHA/GO scaffold was evaluated in vitro and in vivo, and the osteogenic differentiation mechanism of the nanoengineered scaffold was preliminarily investigated. Our data demonstrated that the enhanced osteoinductivity of CMC/nHA/GO may profit from the surface chemistry and roughness, which benefit the β1 integrin interactions with the extracellular matrix and activate the FAK–ERK signaling pathway to upregulate the expression of osteogenic special proteins. This study indicates that the nanocomposite scaffold with surface chemistry and roughness modifications could serve as a novel and promising bone substitute for tissue engineering. The CMC/nHA/GO scaffold with the surface chemistry and roughness dual effects and the release of phosphate and calcium ions synergistically assist the mineralization and facilitate the bone regeneration.![]()

Abstract
Cyclodextrins (CDs) are one of the most versatile substances produced by nature, and it is in the aqueous biological environment where the multifaceted potential of CDs can be completely unveiled. CDs form inclusion complexes with a variety of guest molecules, including polymers, producing very diverse biocompatible supramolecular structures. Additionally, CDs themselves can trigger cell differentiation to distinct lineages depending on the substituent groups and also promote salt nucleation. These features together with the affinity-driven regulated release of therapeutic molecules, growth factors and gene vectors explain the rising interest for CDs as building blocks in regenerative medicine. Supramolecular poly(pseudo)rotaxane structures and zipper-like assemblies exhibit outstanding viscoelastic properties, performing as syringeable implants. The sharp shear-responsiveness of the supramolecular assemblies is opening new avenues for the design of bioinks for 3D printing and also of electrospun fibers. CDs can also be transformed into polymerizable monomers to prepare alternative nanostructured materials. The aim of this review is to analyze the role that CDs may play in regenerative medicine through the analysis of the last decade research. Most applications of CD-based scaffolds are focussed on non-healing bone fractures, cartilage reparation and skin recovery, but also on even more challenging demands such as neural grafts. For the sake of clarity, main sections of this review are organized according to the architecture of the CD-based scaffolds, mainly syringeable supramolecular hydrogels, 3D printed scaffolds, electrospun fibers, and composites, since the same scaffold type may find application in different tissues.

Abstract
It is the first report where different amounts of resol resin (RS) were incorporated with chitosan-hydroxyapatite (CHA) to develop a triconstituent nanoensemble CHA-RS(0.5,1,2), via simple co-precipitation method. The results of SEM, TEM, TGA and mechanical analysis revealed irregular interconnected rough morphology with homogenous distribution of needle shaped particles having average size ranging between 12 and 19nm, possessing higher thermal stability and mechanical strength, respectively relative to CHA (binary) nanocomposite. The CHA-1RS nanocomposite showed enhanced protein adsorption and ALP activity with excellent apatite formation ability compared to CHA-RS(0.5,2) and CHA nanocomposites. Thus, CHA-1RS nanocomposite was selectively tested as bare implant in the repair of critical-size calvarium defect (8mm) in albino rat. The histopathological and radiological investigations indicated that CHA-1RS prompted the bone regeneration ability as early as 2 weeks postimplantation demonstrating remarkably faster healing of calvarial defect relative to Cerabone. These findings have placed CHA-1RS on the pedestal to be employed as a potential alternative biomaterial for bone tissue engineering.
