[PMID: 39227279 DOI: 10.1016/j.jbiosc.2024.07.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 07/28/2024] [Accepted: 07/29/2024] [Indexed: 09/05/2024]
Abstract
Osteochondral tissue engineering using layered scaffolds is a promising approach for treating osteochondral defects as an alternative to microfracture procedure, autologous chondrocyte implantation, and cartilage-bone grafting. The team previously investigated the chondrogenesis of mesenchymal stem cells (MSCs) on a polycaprolactone (PCL)/acetylated hyaluronic acid scaffold. The present study first focused on fabricating a novel osteoconductive scaffold utilizing bismuth-nanohydroxyapatite/reduced graphene oxide (Bi-nHAp/rGO) nanocomposite and electrospun PCL. The osteoconductive ability of the scaffold was investigated by evaluating the alkaline phosphatase (ALP) activity and the osteogenic genes expression in the adipose-derived MSCs. The expression of Runx2, collagen I, ALP, and osteocalcin as well as the result of ALP activity indicated the osteoconductive potential of the Bi-nHA-rGO/PCL scaffold. In the next step, a bilayer scaffold containing Bi-nHAp/rGO/PCL as an osteogenic layer and acetylated hyaluronic acid/PCL as a chondrogenic layer was prepared by the electrospinning technique and transplanted into osteochondral defects of rats. The chondrogenic and osteogenic markers corresponding to the surrounding tissues of the transplanted scaffold were surveyed 60 days later by real-time polymerase chain reaction (PCR) and immunohistochemistry methods. The results showed increased chondrogenic (Sox9 and collagen II) and osteogenic (osteocalcin and ALP) gene expression and augmented secretion of collagens II and X after transplantation. The results strongly support the efficacy of this constructed cell-free bilayer scaffold to induce osteochondral defect regeneration.

Abstract
Inorganic nanoparticulate biomaterials, such as calcium phosphate and bioglass particles, with chemical compositions similar to that of the inorganic component of natural bone, and hence having excellent biocompatibility and bioactivity, are widely used for the fabrication of synthetic bone graft substitutes. Growing evidence suggests that structurally anisotropic, or 1D inorganic micro-/nanobiomaterials are superior to inorganic nanoparticulate biomaterials in the context of mechanical reinforcement and construction of self-supporting 3D network structures. Therefore, in the past decades, efforts have been devoted to developing advanced synthetic scaffolds for bone regeneration using 1D micro-/nanobiomaterials as building blocks. These scaffolds feature extraordinary physical and biological properties, such as enhanced mechanical properties, super elasticity, multiscale hierarchical architecture, extracellular matrix-like fibrous microstructure, and desirable biocompatibility and bioactivity, etc. In this review, an overview of recent progress in the development of advanced scaffolds for bone regeneration is provided based on 1D inorganic micro-/nanobiomaterials with a focus on their structural design, mechanical properties, and bioactivity. The promising perspectives for future research directions are also highlighted.

Abstract
Ultralong nanowires with ultrahigh aspect ratios exhibit high flexibility, and they are promising for applications in various fields. Herein, a cadmium oleate precursor hydrothermal method is developed for the synthesis of ultralong nanowires of cadmium phosphate hydroxide. In this method, water-soluble cadmium salt is used as the cadmium source, water-soluble phosphate is used as the phosphorus source, and sodium oleate is adopted as a reactant to form cadmium oleate precursor and as a structure-directing agent. By using this method, ultralong nanowires of cadmium phosphate hydroxide are successfully synthesized using CdCl2, sodium oleate, and NaH2PO4 as reactants in an aqueous solution by hydrothermal treatment at 180 °C for 24 h. In addition, a new type of flexible fire-resistant inorganic paper with good electrical insulation performance is fabricated using ultralong nanowires of cadmium phosphate hydroxide. As an example of the extended application of this synthetic method, ultralong nanowires of cadmium phosphate hydroxide can be converted to ultralong CdS nanowires through a convenient sulfidation reaction. In this way, ultralong CdS nanowires are successfully synthesized by simple sulfidation of ultralong nanowires of cadmium phosphate hydroxide under mild conditions. The as-prepared ultralong nanowires of cadmium phosphate hydroxide are promising for applications as the precursors and templates for synthesizing other inorganic ultralong nanowires and have wide applications in various fields.

Wet End Chemical Properties of a New Kind of Fire-Resistant Paper Pulp Based on Ultralong Hydroxyapatite Nanowires. Molecules 2022; 27:molecules27206808.

Abstract
In 2014, a new type of the fire-resistant paper based on ultralong hydroxyapatite (HAP) nanowires was reported by the author’s research group, which had superior properties and promising applications in various fields, such as high-temperature resistance, fire retardance, heat insulation, electrical insulation, energy, environmental protection, and biomedicine. The wet end chemical properties of the fire-resistant paper pulp are very important for papermaking and mechanical performance of the paper, which play a guiding role in the practical production of the fire-resistant paper. In this paper, the wet end chemical properties of a new kind of fire-resistant paper pulp based on ultralong HAP nanowires are studied for the first time by focusing on the wet end chemical parameters, the effects of these parameters on the properties such as flocculation, retention, draining, and white water circulation of the fire-resistant paper pulp, and their effects on the properties of the as-prepared fire-resistant paper. The experimental results indicated that the wet end chemical properties of the new kind of fire-resistant paper pulp based on ultralong HAP nanowires were unique and entirely different from those of the traditional paper pulp based on plant fibers. The wet end chemical properties of the fire-resistant paper pulp were significantly influenced by the inorganic adhesive and its content, which affected the runnability of the paper machine and the properties of the as-prepared fire-resistant paper. The flocculation properties of the fire-resistant paper pulp based on ultralong HAP nanowires were affected by the conductivity and Zeta potential. The addition of the inorganic adhesive in the fire-resistant paper pulp based on ultralong HAP nanowires could significantly increase the conductivity of the fire-resistant paper pulp, reduce the particle size of paper pulp floccules, and increase the tensile strength of the fire-resistant paper. In addition, the fire-resistant paper pulp based on ultralong HAP nanowires in the presence of inorganic adhesive exhibited excellent antibacterial performance. This work will contribute to and accelerate the commercialization process and applications of the new type of the fire-resistant paper based on ultralong HAP nanowires.

Abstract
Skin injury that is difficult to heal caused by various factors remains a major clinical challenge. Hydroxyapatite (HAP) has high potential for wound healing owing to its high biocompatibility and adequate angiogenic ability, while traditional HAP materials are not suitable for wound dressing due to their high brittleness and poor mechanical properties. To address this challenge, we developed a novel wound dressing made of flexible ultralong HAP nanowire-based biopaper. This biopaper is flexible and superhydrophilic, with suitable tensile strength (2.57 MPa), high porosity (77%), and adequate specific surface area (36.84 m2·g−1) and can continuously release Ca2+ ions to promote the healing of skin wounds. Experiments in vitro and in vivo show that the ultralong HAP nanowire-based biopaper can effectively induce human umbilical vein endothelial cells (HUVECs) treated with hypoxia and rat skin tissue to produce more angiogenic factors. The as-prepared biopaper can also enhance the proliferation, migration, and in vitro angiogenesis of HUVECs. In addition, the biopaper can promote the rat skin to achieve thicker skin re-epithelialization and the formation of new blood vessels, and thus promote the healing of the wound. Therefore, the ultralong HAP nanowire-based biopaper has the potential to be a safe and effective wound dressing and has significant clinical application prospects.

Abstract
Morphological control can enhance the performance of materials like hydroxyapatite (HAP), a well-known bioceramic with various morphologies, including spheres, rods, whiskers, needles, and plates. To obtain certain HAP morphologies, the crystal growth mechanisms at different planes should be investigated. Here, molecular dynamics was employed to understand the mechanism of HAP nanoparticle growth regulated by glutamic acid (Glu). Long-time dynamics simulations and free energy calculations were performed to explore the effect of Glu on calcium and phosphate ion precipitation on the HAP (100) and (001) faces. Without Glu, PO43- prefers binding to the HAP (100) surface, whereas with Glu, the (001) surface is preferred. This could partially explain why HAP changes from needle-like to plate-like with Glu addition in experiments. Our theoretical results indicate that Glu inhibits calcium and phosphate ion deposition on the crystal surfaces by occupying the calcium sites on the outermost layers. In addition, Glu has a strong concentration gradient effect on HAP deposition. At Glu concentrations of >80 mM, ion deposition was inhibited more on the (100) than on the (001) surface. Our results agree with experimental observations and afford insights into complicated HAP crystal growth mechanisms with foreign additives, which will aid in HAP synthesis with morphological control.

Abstract
Bio-ceramic morphology plays a crucial role in bone repair and regeneration. It is extensively utilized in bone scaffold synthesis due to its better biological system activity and biocompatibility. Here, the ultra-long tricalcium phosphate (UTCP) was synthesized with the assistance of the ultrasonication method. The UTCP is modified as a scaffold by the reinforcement of methacrylate chitosan (MAC) polymer. The functionality of UTCP, UTCP combined MAC, methotrexate (MTX) loaded composites was characterized through FTIR (Fourier transform infrared spectroscopy). The crystalline natures are investigated by the XRD (X-ray diffraction), and results shows the ultra-long tricalcium phosphate crystalline phase is not altered after the reinforcement of MAC polymer and loading of MTX drugs. The morphological analyses were observed through electron microscopic analysis, and rod, polymer-coated rod structures were observed. The UTCP/MAC composite mechanical stress was increased from 1813 Pa of UTCP to 4272 Pa. The MTX loading and release was achieved 79.0 % within 3 h and 76.15 % at 20 h respectively. The UTCP/MAC and UTCP/MAC/MTX's viability investigated osteoblast like the cells (MG-63), and the MTX loaded UTCP/MAC composite exhibits good viability behaviors up to 96.0 % in 14 days. The results confirm the higher compatibility of the composite and profitable cell growth. It may be suitable for bone implantation preparation and it helps in faster regeneration of bone tissue after the in-vivo and clinical evaluation.

Abstract
With the increasing requirement of bone repair materials, hydroxyapatite (HA) has been paid widely attention to investigation because of its good bioactivity and osteoconductivity. The structure of HA is a vital factor to expand its application in the field of hard tissue therapy. Thus, many strategies have been utilized in fabricating one-dimensional (1D) and three-dimensional (3D) nanostructured HA. In this paper, we successful synthesize HA with 1D nanofibers and 3D nanostructured microspheres using stearic acid as a template and different phosphates as phosphorus sources under the same synthetic system. The morphology of HA changes from nanofibers with high flexibility to nanostructured microspheres with good sphericity under the synergistic effect of stearic acid and various phosphates. The HA nanofibers and microspheres are promising for applications in biomedical fields. Base on characterization results, the formation mechanisms of HA nanofibers and HA microspheres self-assembled by nanorods are proposed. Furthermore, the HA morphology transition from nanofibers to nanostructured microspheres may be attributed to the formation of polyphosphate-induced water-in-oil microemulsion system in the synthesis process. The finding may provide a new direction to control HA morphology from 1D nanofibers to 3D microspheres based on previous strategies.
