Abstract
Bone diseases constitute a major issue for modern societies as a consequence of progressive aging. Advantages such as open mesoporous channel, high specific surface area, ease of surface modification, and multifunctional integration are the driving forces for the application of mesoporous nanoparticles (MNs) in bone disease diagnosis and treatment. To achieve better therapeutic effects, it is necessary to understand the properties of MNs and cargo delivery mechanisms, which are the foundation and key in the design of MNs. The main types and characteristics of MNs for bone regeneration, such as mesoporous silica (mSiO2 ), mesoporous hydroxyapatite (mHAP), mesoporous calcium phosphates (mCaPs) are introduced. Additionally, the relationship between the cargo release mechanisms and bone regeneration of MNs-based nanocarriers is elucidated in detail. Particularly, MNs-based smart cargo transport strategies such as sustained cargo release, stimuli-responsive (e.g., pH, photo, ultrasound, and multi-stimuli) controllable delivery, and specific bone-targeted therapy for bone disease diagnosis and treatment are analyzed and discussed in depth. Lastly, the conclusions and outlook about the design and development of MNs-based cargo delivery systems in diagnosis and treatment for bone tissue engineering are provided to inspire new ideas and attract researchers' attention from multidisciplinary areas spanning chemistry, materials science, and biomedicine.

The synergetic effect of bioactive molecule-loaded electrospun core-shell fibres for reconstruction of critical-sized calvarial bone defect-The effect of synergetic release on bone Formation. Cell Prolif 2020; 53:e12796. [PMID: 32202021 PMCID: PMC7162799 DOI: 10.1111/cpr.12796] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 02/18/2020] [Accepted: 02/26/2020] [Indexed: 02/05/2023] Open
Abstract
OBJECTIVES Bone regeneration is a complex process modulated by multiple growth factors and hormones during long regeneration period; thus, designing biomaterials with the capacity to deliver multiple bioactive molecules and obtain sustained release has gained an increasing popularity in recent years. This study is aimed to evaluate the effect of a novel core-shell electrospun fibre loaded with dexamethasone (DEX) and bone morphogenetic protein-2 (BMP-2) on bone regeneration. MATERIALS AND METHODS The core-shell electrospun fibres were fabricated by coaxial electrospinning technology, which were composed of poly-D, L-lactide (PLA) shell and poly (ethylene glycol) (PEG) core embedded with BMP-2 and DEX-loaded micelles. Morphology, hydrophilicity, gradation, release profile of BMP-2 and DEX, and cytological behaviour on bone marrow mesenchymal stem cells (BMSCs) were characterized. Furthermore, the effect on bone regeneration was evaluated via critical-sized calvarial defect model. RESULTS The electrospun fibres were featured by the core-shell fibrous architecture and a suitable degradation rate. The sustained release of DEX and BMP-2 was up to 562 hours. The osteogenic gene expression and calcium deposition of BMSCs were significantly enhanced, indicating the osteoinduction capacity of electrospun fibres. This core-shell fibre could accelerate repair of calvarial defects in vivo via synergistic effect. CONCLUSIONS This core-shell electrospun fibre loaded with DEX and BMP-2 can act synergistically to enhance bone regeneration, which stands as a strong potential candidate for repairing bone defects.

Osteoblast response to zirconia modified-ORMOSILs. MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2019; 109:110546. [PMID: 32228947 DOI: 10.1016/j.msec.2019.110546] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Revised: 11/26/2019] [Accepted: 12/11/2019] [Indexed: 12/27/2022]
Abstract
In this study, an in vitro evaluation of the human osteoblasts response to Organically Modified Silicate (ORMOSIL) biomaterials was conducted. These materials were synthetized by sol-gel process being modified with zirconia (ZrO2) and/or Ca2+. The materials were immersed into phosphate buffer solution (PBS) in order to test precipitation of mimetic apatite-like on their surfaces. ORMOSILs were characterized by SEM, FT-IR and X-RD analysis. The response of osteoblast to ORMOSILs was analyzed as a measure of cell adhesion, proliferation and differentiation. The results showed that the addition of Ca2+ ions modifies the surface morphology of ORMOSILs by forming precipitates of mimetic apatite-like with cauliflower and scales morphologies. On the other hand, biological results suggest that the incorporation of zirconia to ORMOSILs increases their ability to support cell adhesion and proliferation. However, the inclusion of both zirconia and Ca2+ in the ORMOSILs decreases their biological compatibility by showing less cell proliferation and lower osteonectin expression, a protein related to osteoblasts. The unfavorable effect of Ca2+ on cell proliferation and cell viability could be due to its ability to induce the formation of mimetic apatite-like with incompatible morphology. The analysis of other proteins related to bone formation on ORMOSIL-Zr and ORMOSIL-Zr-Ca surfaces demonstrated clear expression of osteopontin and osteocalcin in cells growth. In the case of ORMOSIL-Zr, the expression of osteonectin occurred at early stages while the expression of osteopontin and osteocalcin begun at later stages, indicating a switch from an early to a mature stage being stimulated by the biomaterial. Together, these results highlight the important role of zirconia and Ca2+ ions in the composition of materials regulating their biocompatibility when used as scaffolds in bone regeneration.

Abstract
Tissue regeneration is a significantly improved alternative to tissue replacement by implants. It requires porous bioscaffolds for the restoration of natural tissue rather than relying on bio-inactive, often metallic implants. Recently, we developed technology for fabricating novel, nano-macroporous bioactive 'tailored amorphous multi-porous (TAMP)' hard tissue scaffolds using a 70 mol% SiO2-30 mol% CaO model composition. The TAMP silicate scaffolds, fabricated by a modified sol-gel process, have shown excellent biocompatibility via the rapid formation of hydroxyapatite in biological fluids as well as in early tests with bone forming cells. Here we report an in depth investigation of the response of MC3T3-E1 pre-osteoblast cells and bone marrow derived (BMD) osteoclasts to these TAMP scaffolds. Light and electron microscopic imaging, gene and protein expression, and enzyme activity analyses demonstrate that MC3T3-E1 pre-osteoblasts adhere, proliferate, colonize, and differentiate on and inside the bioactive TAMP scaffolds. Additionally, BMD precursor cells mature into active osteoclasts and remodel the scaffold, highlighting the exceptional qualities of this novel scaffold material for bone tissue regeneration.

Abstract
Bone morphogenetic protein-2 (BMP-2), a growth factor that induces osteoblast differentiation and promotes bone regeneration, has been extensively investigated in bone tissue engineering. The peptides of bioactive domains, corresponding to residues 73-92 of BMP-2 become an alternative to reduce adverse side effects caused by the use of high doses of BMP-2 protein. In this study, BMP-2 peptide functionalized mesoporous silica nanoparticles (MSNs-pep) were synthesized by covalently grafting BMP-2 peptide on the surface of nanoparticles via an aminosilane linker, and dexamethasone (DEX) was then loaded into the channel of MSNs to construct nanoparticulate osteogenic delivery systems (DEX@MSNs-pep). The in vitro cell viability of MSNs-pep was tested with bone mesenchymal stem cells (BMSCs) exposure to different particle concentrations, revealing that the functionalized MSNs had better cytocompatibility than their bare counterparts, and the cellular uptake efficiency of MSNs-pep was remarkably larger than that of bare MSNs. The in vitro results also show that the MSNs-pep promoted osteogenic differentiation of BMSCs in terms of the levels of alkaline phosphatase (ALP) activity, calcium deposition, and expression of bone-related protein. Moreover, the osteogenic differentiation of BMSCs can be further enhanced by incorporating of DEX into MSNs-pep. After intramuscular implantation in rats for 3 weeks, the computed tomography (CT) images and histological examination indicate that this nanoparticulate osteogenic delivery system induces effective osteoblast differentiation and bone regeneration in vivo. Collectively, the BMP-2 peptide and DEX incorporated MSNs can act synergistically to enhance osteogenic differentiation of BMSCs, which have potential applications in bone tissue engineering.

Abstract
Bone morphogenetic protein-2 (BMP-2) is considered one of the most effective and extensively used growth factors to induce osteoblast differentiation and accelerate bone regeneration. Dexamethasone (Dex) with suitable dosage can enhance BMP-2-induced osteoblast differentiation. To strengthen this synergistic osteoinductive effect, a pH-responsive chitosan-functionalized mesoporous silica nanoparticle (chi-MSN) ensemble was fabricated for dual-delivery of BMP-2 and Dex. The MSNs are prepared by a CTAB-templated sol-gel method, and further coated by chitosan via the crosslinking of glycidoxypropyltrimethoxysilane (GPTMS). The small Dex is encapsulated in the mesopores and the large BMP-2 is incorporated into the chitosan coating. These chi-MSNs can quickly release BMP-2 in a bioactive form and can then be efficiently endocytosed and further realize a controlled release of Dex with the decreased pH value into/in cells. With the synergistic action of BMP-2 and Dex outside and inside the cell, this dual hybrid delivery system can significantly stimulate osteoblast differentiation and bone regeneration in vitro and in vivo. Together, this dual-delivery strategy for osteogenic protein delivery may enhance clinical outcomes by retaining the bioactivity and optimizing the release mode of the drug/protein.
