Castaño IM, Raftery RM, Chen G, Cavanagh B, Quinn B, Duffy GP, Curtin CM, O'Brien FJ. Dual scaffold delivery of miR-210 mimic and miR-16 inhibitor enhances angiogenesis and osteogenesis to accelerate bone healing. Acta Biomater 2023; 172:480-493. [PMID: 37797708 DOI: 10.1016/j.actbio.2023.09.049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 08/30/2023] [Accepted: 09/28/2023] [Indexed: 10/07/2023]
Abstract
Angiogenesis is critical for successful bone repair, and interestingly, miR-210 and miR-16 possess counter-active targets involved in both angiogenesis and osteogenesis: miR-210 acts as an activator by silencing EFNA3 & AcvR1b, while miR-16 inhibits both pathways by silencing VEGF & Smad5. It was thus hypothesized that dual delivery of both a miR-210 mimic and a miR-16 inhibitor from a collagen-nanohydroxyapatite scaffold system may hold significant potential for bone repair. Therefore, this systems potential to rapidly accelerate bone repair by directing enhanced angiogenic-osteogenic coupling in host cells in a rat calvarial defect model at a very early 4 week timepoint was assessed. In vitro, the treatment significantly enhanced angiogenic-osteogenic coupling of human mesenchymal stem cells, with enhanced calcium deposition after just 10 days in 2D and 14 days on scaffolds. In vivo, these dual-miRNA loaded scaffolds showed more than double bone volume and vessel recruitment increased 2.3 fold over the miRNA-free scaffolds. Overall, this study demonstrates the successful development of a dual-miRNA mimic/inhibitor scaffold for enhanced in vivo bone repair for the first time, and the possibility of extending this 'off-the-shelf' platform system to applications beyond bone offers immense potential to impact a myriad of other tissue engineering areas. STATEMENT OF SIGNIFICANCE: miRNAs have potential as a new class of bone healing therapeutics as they can enhance the regenerative capacity of bone-forming cells. However, angiogenic-osteogenic coupling is critical for successful bone repair. Therefore, this study harnesses the delivery of miR-210, known to be an activator of both angiogenesis and osteogenesis, and miR-16 inhibitor, as miR-16 is known to inhibit both pathways, from a collagen-nanohydroxyapatite scaffold system to rapidly enhance osteogenesis in vitro and bone repair in vivo in a rat calvarial defect model. Overall, it describes the successful development of the first dual-miRNA mimic/inhibitor scaffold for enhanced in vivo bone repair. This 'off-the-shelf' platform system offers immense potential to extend beyond bone applications and impact a myriad of other tissue engineering areas.

Abstract
MicroRNAs are short, single-stranded ribonucleic acids expressed endogenously in the body to regulate gene expression at the post-translational level, with exogenous microRNA offering an attractive approach to therapy. Among the myriad microRNA candidates involved in controlling bone homeostasis and remodeling, microRNA 21 (miR21) is the most abundant. This paper discusses the studies conducted on the role and mechanism of human miR21 (hsa-miR21) in the regulation of bones and the various pathways mediated by miR21, and explores the feasibility of employing exogenous miR21 as a strategy for promoting osteogenesis. From the literature review, it was clear that miR21 plays a dual role in bone metabolism by regulating both bone formation and bone resorption. There is substantial evidence to date from both in vitro and in vivo studies that exogenous miR21 can successfully accelerate new bone synthesis in the context of bone loss due to injury or osteoporosis. This supports the exploration of applications of exogenous miR21 in bone regenerative therapy in the future.

Abstract
Extensive diaphyseal and metaphyseal bone defects continue to pose a major challenge for orthopedic trauma surgeons. Various treatment options have been described for the biological reconstruction of these defects. The most frequently used methods are bone segment transport, the Masquelet technique and 3D printed scaffolds. As far as the Masquelet technique is concerned, in the first stage spacers, such as polymethyl methacrylate (PMMA), calcium sulfate or polypropylene are inserted into the bone defects to induce a foreign body membrane. In the second stage the bone defect surrounded by the induced membrane is filled with autologous cancellous bone. The time interval between the first and second interventions is usually 4-8 weeks whereby the induced membranes do not lose their bioactivity even with a latency period longer than 8 weeks. Three-dimensional printed scaffolds are increasingly used but large clinical studies are lacking in order to show the exact role of this procedure in the reconstruction of bone defects.

Abstract
The clinical need for bone regenerative solutions is expanding with increasing life expectancy and escalating incidence of accidents. Several strategies are being investigated to enhance the osteogenic differentiation of stem cells. We previously reported two different approaches for this purpose, in monolayer and three-dimensional cell culture. The first approach was based on pretreating cells with 5-Aza-dC, a DNA methylation inhibitor, before the applying the differentiation media. The second approach was based on culturing cells on a glass surface during differentiation. In this study, we investigated the potential effect of combining both methods. Our results suggested that both approaches were associated with decreasing global DNA methylation levels. Cells cultured as a monolayer on glass surface showed enhancement in alkaline phosphatase activity at day 10, while 5-Aza-dC pretreatment enhanced the activity at day 5, irrespective of the culture surface. In three-dimensional pellet culture, 5-Aza-dC pretreatment enhanced osteogenesis through Runx-2 and TGF-β1 upregulation while the glass surface induced Osterix. Furthermore, pellets cultured on glass showed upregulation of a group of miRNAs, including pro-osteogenesis miR- 20a and miR -148b and anti-osteogenesis miR -125b, miR -31, miR -138, and miR -133a. Interestingly, 5-Aza-dC was not associated with a change of miRNAs in cells cultured on tissue culture plastic but reverted the upregulated miRNAs on the glass to the basal level. This study confirms the two approaches for enhancing osteogenic differentiation and contradicts their combination.

Abstract
Millions of people around the world have bone-tissue defects. Autologous and allogeneic bone grafting are frequent therapeutic techniques; however, none has produced the best therapeutic results. This has inspired researchers to investigate novel bone-regeneration technologies. In recent years, the development of bone tissue engineering (BTE) scaffolds has been at the forefront of this discipline. Due to their limitless supply and lack of disease transmission, engineered bone tissue has been advanced for the repair and reconstruction of bone deformities. Bone tissue is a highly vascularized, dynamic tissue that constantly remodels during an individual's lifetime. Bone tissue engineering is aimed at stimulating the creation of new, functional bone by combining biomaterials, cells, and factor treatment synergistically. This article provides a review of wollastonite's biomaterial application in bone tissue engineering. This work includes an explanation of wollastonite minerals including mining, raw materials for the synthesis of artificial wollastonite with various methods, its biocompatibility, and biomedical applications. Future perspectives are also addressed, along with topics like bone tissue engineering, the qualities optimal bone scaffolds must have, and the way a scaffold is designed can have a big impact on how the body reacts.

Abstract
Breast cancer is a complex disease with multiple risk factors involved in its pathogenesis. Among these factors, microRNAs are considered for playing a fundamental role in the development and progression of malignant breast tumors. In recent years, various studies have demonstrated that several microRNAs exhibit increased or decreased expression in metastatic breast cancer, acting as indicators of metastatic potential in body fluids and tissue samples. The identification of these microRNA expression patterns could prove instrumental for the development of novel therapeutic molecules that either mimic or inhibit microRNA action. Additionally, an efficient delivery system mediated by viral vectors, nonviral carriers, or scaffold biomaterials is a prerequisite for implementing microRNA-based therapies; therefore, this review attempts to highlight essential microRNA molecules involved in the metastatic process of breast cancer and discuss recent advances in microRNA-based therapeutic approaches with potential future applications to the treatment sequence of breast cancer.

Abstract
Circular RNAs (circRNAs) are emerging as important regulators in bone metabolism, which is mediated by microRNA (miRNA) sponges. However, it is not clear how circRNA regulates osteogenic differentiation of human bone marrow mesenchymal stem cells (hBM-MSCs).Therefore, based on the previous circRNA chip results, hsa_circ_0006766, which is differentially expressed in the osteogenic differentiation of hBM-MSCs, was screened out, and bioinformatics analysis was performed to predict potential target miRNAs. During osteogenic differentiation of hBM-MSCs, hsa_circ_0006766 and its target miRNAs (miR-4739, miR-619-5p, miR-5787, miR-7851-3p, and miR-3192-5p) were detected by quantitative Real Time-PCR (qRT-PCR). Target gene prediction for the differentially expressed target miRNAs was performed, and target genes were validated by dual-luciferase reporter gene assay and qRT-PCR. It is shown that hsa_circ_0006766 was up-regulated and miR-4739 was down-regulated during osteogenic differentiation of hBM-MSCs.Moreover, the target gene Notch2 was predicted to be highly expressed during osteogenic differentiation. And dual-luciferase assay proved that Notch2 was the gene targeting to miR-4739. Taken together, our finding confirmed that hsa_circ_0006766 may act as a major regulatory part in osteogenic differentiation of hBM-MSCs via an hsa_circ_0006766–miR-4739–Notch2 regulatory axis. Accordingly, hsa_circ_0006766 may affect the development of osteoporosis and may thus become a therapeutic target.

Abstract
Mesenchymal stem cells (MSCs) have been identified in many adult tissues. MSCs can regenerate through cell division or differentiate into adipocytes, osteoblasts and chondrocytes. As a result, MSCs have become an important source of cells in tissue engineering and regenerative medicine for bone tissue and cartilage. Several epigenetic factors are believed to play a role in MSCs differentiation. Among these, microRNA (miRNA) regulation is involved in the fine modulation of gene expression during osteogenic/chondrogenic differentiation. It has been reported that miRNAs are involved in bone homeostasis by modulating osteoblast gene expression. In addition, countless evidence has demonstrated that miRNAs dysregulation is involved in the development of osteoporosis and bone fractures. The deregulation of miRNAs expression has also been associated with several malignancies including bone cancer. In this context, bone-associated circulating miRNAs may be useful biomarkers for determining the predisposition, onset and development of osteoporosis, as well as in clinical applications to improve the diagnosis, follow-up and treatment of cancer and metastases. Overall, this review will provide an overview of how miRNAs activities participate in osteogenic/chondrogenic differentiation, while addressing the role of miRNA regulatory effects on target genes. Finally, the role of miRNAs in pathologies and therapies will be presented.

Abstract
Objective To investigate whether exosomes derived from miR-27a-overexpressing human umbilical vein endothelial cells (HUVECs)-exo (miR-27a) can promote bone regeneration and improve glucocorticoids (GC) induced osteonecrosis of femoral head (ONFH) (GC-ONFH). Methods The exo (miR-27a) were intended to be constructed and identified by transmission electron microscopy, nanoparticle tracking analysis, Western blot, and real-time fluorescent quantitative PCR (qRT-PCR). qRT-PCR was used to evaluate the effect of exo (miR-27a) in delivering miR-27a to osteoblasts (MC3T3-E1 cells). Alkaline phosphatase staining, alizarin red staining, and qRT-PCR were used to evaluate its effect on MC3T3-E1 cells osteogenesis. Dual-luciferase reporter (DLRTM) assay was used to verify whether miR-27a targeting Dickkopf WNT signaling pathway inhibitor 2 (DKK2) was a potential mechanism, and the mechanism was further verified by qRT-PCR, Western blot, and alizarin red staining in MC3T3-E1 cells. Finally, the protective effect of exo (miR-27a) on ONFH was verified by the GC-ONFH model in Sprague Dawley (SD) rats. Results Transmission electron microscopy, nanoparticle tracking analysis, Western blot, and qRT-PCR detection showed that exo (miR-27a) was successfully constructed. exo (miR-27a) could effectively deliver miR-27a to MC3T3-E1 cells and enhance their osteogenic capacity. The detection of DLRTM showed that miR-27a promoted bone formation by directly targeting DDK2. Micro-CT and HE staining results of animal experiments showed that tail vein injection of exo (miR-27a) improved the osteonecrosis of SD rat GC-ONFH model. Conclusion exo (miR-27a) can promote bone regeneration and protect against GC-ONFH to some extent.

Abstract
This review showcases miRNAs contributing to the regulation of bone forming osteoblasts through their effects on the TGFβ and BMP pathways, with a focus on ligands, receptors and SMAD-mediated signaling. The goal of this work is to provide a basis for broadly understanding the contribution of miRNAs to the modulation of TGFβ and BMP signaling in the osteoblast lineage, which may provide a rationale for potential therapeutic strategies. Therefore, the search strategy for this review was restricted to validated miRNA-target interactions within the canonical TGFβ and BMP signaling pathways; miRNA-target interactions based only bioinformatics are not presented. Specifically, this review discusses miRNAs targeting each of the TGFβ isoforms, as well as BMP2 and BMP7. Further, miRNAs targeting the signaling receptors TGFβR1 and TGFβR2, and those targeting the type 1 BMP receptors and BMPR2 are described. Lastly, miRNAs targeting the receptor SMADs, the common SMAD4 and the inhibitory SMAD7 are considered. Of these miRNAs, the miR-140 family plays a prominent role in inhibiting TGFβ signaling, targeting both ligand and receptor. Similarly, the miR-106 isoforms target both BMP2 and SMAD5 to inhibit osteoblastic differentiation. Many of the miRNAs targeting TGFβ and BMP signaling components are induced during fracture, mechanical unloading or estrogen deprivation. Localized delivery of miRNA-based therapeutics that modulate the BMP signaling pathway could promote bone formation.

Abstract
BACKGROUND Steroid-induced osteonecrosis of the femoral head (SONFH) is a devastating orthopedic disease, which seriously affects the quality of life of patients. The study aims to investigate the effects of LncRNA NORAD on SONFH. METHODS Human bone marrow-derived mesenchymal stem cells (hBMSCs) were isolated from the proximal femur of patients during routine orthopedic surgery and then cultured with dexamethasone (Dex) and transfected with NORAD overexpression vector, siRNA-NORAD and miR-26a-5p mimics. The mRNA expression of NORAD, miR-26a-5p, OPG, RANK, and RANKL was detected by RT-qPCR. Cell proliferation and apoptosis was measured by CCK-8 assay and flow cytometry, respectively. The protein expression of RUNX2, OPG, RANK, and RANKL was detected by western blot. The dual-luciferase reporter gene assay was performed to confirm the binding between NORAD and miR-26a-5p. RESULTS NORAD expression was downregulated in SONFH tissues, while miR-26a-5p expression was upregulated. Overexpression of NORAD improved DEX-induced inhibition of proliferation and differentiation, and promotion of apoptosis in hBMSCs, while knockdown of NORAD led to the opposite results. Moreover, NORAD improved DEX-induced inhibition of proliferation and differentiation, and promotion of apoptosis by regulation of miR-26a-5p in hBMSCs. CONCLUSIONS NORAD expression was downregulated in SONFH tissues, while miR-26a-5p expression was upregulated. NORAD improved DEX-induced inhibition of proliferation and differentiation, and promotion of apoptosis by regulation of miR-26a-5p in hBMSCs.

Liu M, Xu Z. Berberine Promotes the Proliferation and Osteogenic Differentiation of Alveolar Osteoblasts through Regulating the Expression of miR-214. Pharmacology 2020; 106:70-78. [PMID: 32688361 DOI: 10.1159/000508972] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Accepted: 05/25/2020] [Indexed: 11/19/2022]
Abstract
INTRODUCTION AND OBJECTIVE Alveolar osteoblasts have critical functions during alveolar bone regeneration. Berberine (BBR) and microRNAs (miRNAs) are considered to play important roles in regulating osteoblast differentiation. The study aimed to investigate the role and mechanisms of BBR in osteogenic differentiation of human alveolar osteoblasts (HAOBs) and determine miR-214 expression in the process. METHODS Healthy human alveolar bones were cultured in vitro and prepared for morphological observation and alkaline phosphatase (ALP) staining. The third generation of HAOBs was used for cell transfection and treated by different concentrations of BBR. Cell Counting Kit-8 was used to detect the effect of BBR and increased miR-214 on the proliferation of HAOBs. qRT-PCR and Western blot were used to detect the expression of osteogenic differentiation-related genes and miR-214 level, respectively. RESULTS The ALP staining results were positive, indicating that cultured cells were HAOBs. Different concentrations of BBR significantly promoted the proliferation of HAOBs and increased the expression levels of ALP, osteocalcin (OCN), collagen type I alpha 1 (COL1A1), runt related transcription factor 2 (RUNX2), and osterix (OSX). Moreover, the expression of miR-214 was reduced as BBR concentrations increased, and the increase of miR-214 reversed the BBR-induced proliferation and osteogenic differentiation of HAOBs. CONCLUSION BBR could promote the proliferation and osteogenic differentiation of HAOBs through downregulating the expression of miR-214.

Rapid bone repair with the recruitment of CD206 +M2-like macrophages using non-viral scaffold-mediated miR-133a inhibition of host cells. Acta Biomater 2020; 109:267-279. [PMID: 32251781 DOI: 10.1016/j.actbio.2020.03.042] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 03/10/2020] [Accepted: 03/27/2020] [Indexed: 01/01/2023]
Abstract
microRNAs offer vast therapeutic potential for multiple disciplines. From a bone perspective, inhibition of miR-133a may offer potential to enhance Runx2 activity and increase bone repair. This study aims to assess the therapeutic capability of antagomiR-133a delivery from collagen-nanohydroxyapatite (coll-nHA) scaffolds following cell-free implantation in rat calvarial defects (7 mm diameter). This is, to the best of our knowledge, the first report of successful in vivo antagomiR uptake in host cells of fully immunocompetent animals without distribution to other off-target tissues. Our results demonstrate the localized release of antagomiR-133a to the implant site at 1 week post-implantation with increased calcium deposits already evident in the antagomiR-133a loaded scaffolds at this early timepoint. This was followed by an approximate 2-fold increase in bone volume versus antagomiR-free scaffolds and a significant 10-fold increase over the empty defect controls, after just 4 weeks. An increase in host CD206+ cells suggests an accelerated pro-remodeling response by M2-like macrophages accompanying bone repair with this treatment. Overall, this non-viral scaffold-mediated antagomiR-133a delivery platform demonstrates capability to accelerate bone repair in vivo - without the addition of exogenous cells - and underlines the role of M2 macrophage-like cells in directing accelerated bone repair. Expanding the repertoire of this platform to deliver alternative miRNAs offers exciting possibilities for a variety of therapeutic indications. STATEMENT OF SIGNIFICANCE: microRNAs, small non-coding RNA molecules involved in gene regulation, may have potential as a new class of bone healing therapeutics as they can enhance the regenerative capacity of bone-forming cells. We developed a collagen-nanohydroxyapatite-microRNA scaffold system to investigate whether miR133a inhibition can enhance osteogenesis in rat MSCs and ultimately accelerate endogenous bone repair by host cells in vivo without pre-seeding cells prior to implantation. Overall, this off-the-shelf, non-viral scaffold-mediated antagomiR-133a delivery platform demonstrates capability to accelerate bone repair in vivo - without the requirement of exogenous cells - and highlights the role of CD206+M2 macrophage-like cells in guiding accelerated bone repair. Translating the repertoire of this platform to deliver alternative miRNAs offers exciting possibilities for a vast myriad of therapeutic indications.

Abstract
Bone-related injury and disease constitute a significant global burden both socially and economically. Current treatments have many limitations and thus the development of new approaches for bone-related conditions is imperative. Gene therapy is an emerging approach for effective bone repair and regeneration, with notable interest in the use of RNA interference (RNAi) systems to regulate gene expression in the bone microenvironment. Calcium phosphate nanoparticles represent promising materials for use as non-viral vectors for gene therapy in bone tissue engineering applications due to their many favorable properties, including biocompatibility, osteoinductivity, osteoconductivity, and strong affinity for binding to nucleic acids. However, low transfection rates present a significant barrier to their clinical use. This article reviews the benefits of calcium phosphate nanoparticles for RNAi delivery and highlights the role of surface functionalization in increasing calcium phosphate nanoparticles stability, improving cellular uptake and increasing transfection efficiency. Currently, the underlying mechanistic principles relating to these systems and their interplay during in vivo bone formation is not wholly understood. Furthermore, the optimal microRNA targets for particular bone tissue regeneration applications are still unclear. Therefore, further research is required in order to achieve the optimal calcium phosphate nanoparticles-based systems for RNAi delivery for bone tissue regeneration.

Abstract
Bone injuries and diseases constitute a burden both socially and economically, as the consequences of a lack of effective treatments affect both the patients' quality of life and the costs on the health systems. This impended need has led the research community's efforts to establish efficacious bone tissue engineering solutions. There has been a recent focus on the use of biomaterial-based nanoparticles for the delivery of therapeutic factors. Among the biomaterials being considered to date, calcium phosphates have emerged as one of the most promising materials for bone repair applications due to their osteoconductivity, osteoinductivity and their ability to be resorbed in the body. Calcium phosphate nanoparticles have received particular attention as non-viral vectors for gene therapy, as factors such as plasmid DNAs, microRNAs (miRNA) and silencing RNA (siRNAs) can be easily incorporated on their surface. Calcium phosphate nanoparticles loaded with therapeutic factors have also been delivered to the site of bone injury using scaffolds and hydrogels. This review provides an extensive overview of the current state-of-the-art relating to the design and synthesis of calcium phosphate nanoparticles as carriers for therapeutic factors, the mechanisms of therapeutic factors' loading and release, and their application in bone tissue engineering.

Abstract
Joint replacement and bone reconstructive surgeries are on the rise globally. Current strategies for implants and bone regeneration are associated with poor integration and healing resulting in repeated surgeries. A multidisciplinary approach involving basic biological sciences, tissue engineering, regenerative medicine and clinical research is required to overcome this problem. Considering the nanostructured nature of bone, expertise and resources available through recent advancements in nanobiotechnology enable researchers to design and fabricate devices and drug delivery systems at the nanoscale to be more compatible with the bone tissue environment. The focus of this review is to present the recent progress made in the rationale and design of nanomaterials for tissue engineering and drug delivery relevant to bone regeneration.

Abstract
Bone is one of the most dynamic organs in the body that continuously undergoes remodeling through bone formation and resorption. A cascade of molecules and pathways results in the osteoblast differentiation that is attributed to osteogenesis, or bone formation. The process of osteogenesis is achieved through participation of the Wnt pathway, FGFs, BMPs/TGF-β, and transcription factors such as Runx2 and Osx. The activity and function of the master transcription factor, Runx2, is of utmost significance as it can induce the function of osteoblast differentiation markers. A number of microRNAs [miRNAs] have been recently identified in the regulation of Runx2 expression/activity, thus affecting the process of osteogenesis. miRNAs that target Runx2 corepressors favor osteogenesis, while miRNAs that target Runx2 coactivators inhibit osteogenesis. In this review, we focus on the regulation of Runx2 by miRNAs in osteoblast differentiation and their potential for treating bone and bone-related diseases.

Abstract
In recent years, the application of microRNAs (miRNAs) or anti-microRNAs (anti-miRNAs) that can induce expression of the runt-related transcription factor 2 (RUNX2), a master regulator of osteogenesis, has been investigated as a promising alternative bone tissue engineering strategy. In this review, biomaterial scaffold-based applications that have been used to deliver cells expressing miRNAs or anti-miRNAs that induce expression of RUNX2 for bone tissue engineering are discussed. An overview of the components of the scaffold-based therapies including the miRNAs/anti-miRNAs, cell types, gene delivery vectors, and scaffolds that have been applied are provided. To date, there have been nine miRNAs/anti-miRNAs (i.e., miRNA-26a, anti-miRNA-31, anti-miRNA-34a, miRNA-135, anti-miRNA-138, anti-miRNA-146a, miRNA-148b, anti-miRNA-221, and anti-miRNA-335) that have been incorporated into scaffold-based bone tissue engineering applications and investigated in an in vivo bone critical-sized defect model. For all of the biomaterial scaffold-based miRNA therapies that have been developed thus far, cells that are transfected or transduced with the miRNA/anti-miRNA are loaded into the scaffolds and implanted at the site of interest instead of locally delivering the miRNA/anti-miRNAs directly from the scaffolds. Thus, future work may focus on developing biomaterial scaffolds to deliver miRNAs or anti-miRNAs into cells in vivo.

Abstract
Delivery of osteogenesis-promoting microRNAs (miRNAs) is a promising approach to enhance bone regeneration. In this study, we generated nanocomplexes comprising the novel cell-penetrating peptide R9-LK15 and miR-29b and investigated their effects on osteogenic differentiation of bone mesenchymal stem cells (BMSCs). R9-LK15/miR-29b nanocomplexes were prepared and characterized. The transfection efficiency, cell viability, and osteogenic differentiation were investigated. The results showed that R9-LK15 maintained the stability of miR-29b in serum for up to 24 h. Moreover, R9-LK15 efficiently delivered miR-29b into BMSCs; the transfection efficiency was ~10-fold higher than that achieved using Lipofectamine 2000. The Cell Counting Kit-8 assay showed that R9-LK15 and R9-LK15/miR-29b nanocomplexes had negligible cytotoxic effects on BMSCs. Delivery of R9-LK15/miR-29b nanocomplexes promoted osteogenic differentiation of BMSCs and extracellular matrix mineralization by upregulating alkaline phosphatase expression and downregulating histone deacetylase-4 expression. In general, we developed a novel miRNA delivery system that has a high transfection efficiency and promotes osteogenic differentiation.

Abstract
Emerging evidence demonstrates that microRNAs, as important endogenous posttranscriptional regulators, are essential for bone remodeling and regeneration. Undoubtedly, microRNA-based gene therapies show great potential to become novel approaches against bone-related diseases, including osteoporosis and associated fractures. The major obstacles for continued advancement of microRNA-based therapies in clinical application include their poor in vivo stability, nonspecific biodistribution, and unwanted side effects. Appropriate chemical modifications and delivery vectors, which improve the biological performance and potency of microRNA-based drugs, hold the key to translating miRNA technologies into clinical practice. Thus, this review summarizes the current attempts and existing deficiencies of chemical modifications and delivery systems applied in microRNA-based therapies for osteoporosis and osteoporotic fractures to inform further explorations.

Abstract
The development, maintenance of healthy bone and regeneration of injured tissue in the human body comprise a set of intricate and finely coordinated processes. However, an analysis of current bone regeneration strategies shows that only a small fraction of well-reported bone biology aspects has been used as inspiration and transposed into the development of therapeutic products. Specific topics that include inter-scale bone structural organization, developmental aspects of bone morphogenesis, bone repair mechanisms, role of specific cells and heterotypic cell contact in the bone niche (including vascularization networks and immune system cells), cell-cell direct and soluble-mediated contact, extracellular matrix composition (with particular focus on the non-soluble fraction of proteins), as well as mechanical aspects of native bone will be the main reviewed topics. In this Review we suggest a systematic parallelization of (i) fundamental well-established biology of bone, (ii) updated and recent advances on the understanding of biological phenomena occurring in native and injured tissue, and (iii) critical discussion of how those individual aspects have been translated into tissue regeneration strategies using biomaterials and other tissue engineering approaches. We aim at presenting a perspective on unexplored aspects of bone physiology and how they could be translated into innovative regeneration-driven concepts.

The control of alginate degradation to dynamically manipulate scaffold composition for in situ transfection application. Int J Biol Macromol 2018; 117:1169-1178.

Abstract
In this study, nanofibrous scaffolds were used for in situ transfection application. Polyethylenimine (PEI)/DNA complexes adsorbed to alginate nanofibers, so the more alginate fibers resulted in the higher transfection efficiency. However, alginate was not favorable for cell adhesion. Therefore, poly (ε‑caprolactone) (PCL) nanofibers were electrospun with alginate to improve biocompatibility. The in situ transfection results demonstrated that although the incorporated PCL fibers effectively improved cell morphology, the bioactivity and proliferation rates of surface cells were not significantly increased due to the high ratio of alginate fibers. However, the reduction of the alginate ratio may decrease transfection efficiency because the immobilization of nonviral vectors linearly depended on the density of alginate fibers. To maintain transfection efficiency and increase biocompatibility, the stability of alginate fibers were manipulated by adjusting the concentrations of calcium ions during crosslinking. These partially crosslinked alginate fibers were initially intact to allow nanoparticle adsorption for cell uptake, and then gradually degraded in days to create an appropriate environment for cell survival. This dynamic system successfully fulfilled the requirements of both gene delivery and biocompatibility. To our knowledge, this study may be the first one which dynamically regulates scaffold composition for substrate-mediated gene delivery.

Abstract
MicroRNA (miRNA) therapeutics is increasingly being developed to either target bone-related diseases such as osteoporosis and osteoarthritis or as the basis for novel bone tissue engineering strategies. A number of miRNAs have been reported as potential osteo-therapeutics but no consensus has yet been established on the optimal target. miR-16 has been studied extensively in nonosteogenic functions and used as functionality reporter target in the development of nonviral miRNA delivery platforms. This study hypothesized that miR-16 may also play an inhibitory role in osteogenesis due to its ability to directly target Smad5 and AcvR2a. This study thus aimed to assess the potential of miR-16 inhibition to increase osteogenesis in human mesenchymal stem cells (hMSCs) using a previously established miRNA delivery platform composed of nanohydroxyapatite (nHA) particles as nonviral vectors in combination with collagen-nHA scaffolds designed specifically for bone repair. Initial results showed that antagomiR-16 delivery efficiently increased the relative levels of both putative targets and Runx2, the key transcription factor for osteogenesis, while also increasing osteocalcin levels. Furthermore, significant increases in mineral calcium deposition by hMSCs were found in both monolayer and most importantly in scaffold-based osteodifferentiation studies, ultimately demonstrating that miR-16 inhibition further enhances the therapeutic potential of a scaffold with known potential for bone repair applications and thus holds significant therapeutic potential as a novel bone tissue engineering strategy. Furthermore, we suggest that harnessing the additional functions known to miR-16 by incorporating either its enhancers or inhibitors to tissue-specific tailored scaffolds provides exciting opportunities for a diverse range of therapeutic indications.

Abstract
Bone tissue engineering (BTE) relies on biocomposite scaffolds and bioactive molecules for bone regeneration. The present study was aimed to synthesize and characterize biocomposite scaffolds containing chitosan (CS), nano-hydroxyapatite (nHAp) and nano‑zirconium dioxide (nZrO2) along with microRNA (miRNA) for BTE applications. miRNAs act as post-transcriptional regulator of gene expression. The fabricated biocomposite scaffolds were characterized using SEM, FT-IR and XRD analyses. The effect of a bioactive molecule (miR-590-5p) with scaffolds was tested for osteoblast differentiation at the cellular and molecular levels using mouse mesenchymal stem cells (C3H10T1/2). The results showed that CS/nHAp/nZrO2 scaffolds promoted osteoblast differentiation, and this effect was further increased in the presence of miR-590-5p in C3H10T1/2 cells. Thus, we suggested that CS/nHAp/nZrO2 scaffolds with miR-590-5p would have potential towards the treatment of bone defects.

Abstract
microRNA-based therapies are an advantageous strategy with applications in both regenerative medicine (RM) and cancer treatments. microRNAs (miRNAs) are an evolutionary conserved class of small RNA molecules that modulate up to one third of the human nonprotein coding genome. Thus, synthetic miRNA activators and inhibitors hold immense potential to finely balance gene expression and reestablish tissue health. Ongoing industry-sponsored clinical trials inspire a new miRNA therapeutics era, but progress largely relies on the development of safe and efficient delivery systems. The emerging application of biomaterial scaffolds for this purpose offers spatiotemporal control and circumvents biological and mechanical barriers that impede successful miRNA delivery. The nascent research in scaffold-mediated miRNA therapies translates know-how learnt from studies in antitumoral and genetic disorders as well as work on plasmid (p)DNA/siRNA delivery to expand the miRNA therapies arena. In this progress report, the state of the art methods of regulating miRNAs are reviewed. Relevant miRNA delivery vectors and scaffold systems applied to-date for RM and cancer treatment applications are discussed, as well as the challenges involved in their design. Overall, this progress report demonstrates the opportunity that exists for the application of miRNA-activated scaffolds in the future of RM and cancer treatments.

Abstract
Bioactive glass nanoparticles (BGNs) have attracted much attention in drug delivery and bone tissue regeneration, due to the advantages including biodegradation, high bone-bonding bioactivity, and facile large-scale fabrication. However, the wide biomedical applications of BGNs such as efficient gene delivery are limited due to their poor pore structure and easy aggregation. Herein, for the first time, this study reports novel monodispersed bioactive glass nanoclusters (BGNCs) with ultralarge mesopores (10-30 nm) and excellent miRNA delivery for accelerating critical-sized bone regeneration. BGNCs with different size (100-500 nm) are fabricated by using a branched polyethylenimine as the structure director and catalyst. BGNCs show an excellent apatite-forming ability and high biocompatibility. Importantly, BGNCs demonstrate an almost 19 times higher miRNA loading than those of conventional BGNs. Additionally, BGNCs-miRNA nanocomplexes exhibit a significantly high antienzymolysis, enhance cellular uptake and miRNA transfection efficiency, overpassing BGNs and commercial Lipofectamine 3000. BGNCs-mediated miRNA delivery significantly improves the osteogenic differentiation of bone marrow stromal stem cells in vitro and efficiently enhances bone formation in vivo. BGNCs can be a highly efficient nonviral vector for various gene therapy applications. The study may provide a novel strategy to develop highly gene-activated bioactive nanomaterials for simultaneous tissue regeneration and disease therapy.

Abstract
Silibinin is a plant derived flavonolignan known for its multiple biological properties, but its role in the promotion of bone formation has not yet been well studied. Moreover, the delivery of Silibinin is hindered by its complex hydrophobic nature, which limits its bioavailability. Hence, in this study, we fabricated a drug delivery system using chitosan nanoparticles loaded with Silibinin at different concentrations (20μM, 50μM, and 100μM). They were then incorporated into scaffolds containing Alginate and Gelatin (Alg/Gel) for the sustained and prolonged release of Silibinin. The Silibinin-loaded chitosan nanoparticles (SCN) were prepared using the ionic gelation technique, and the scaffolds (Alg/Gel-SCN) were synthesized by the conventional method of freeze drying. The scaffolds were subjected to physicochemical and material characterization studies. The addition of SCN did not affect the porosity of the scaffolds, yet increased the protein adsorption, degradation rates, and bio-mineralization. These scaffolds were biocompatible with mouse mesenchymal stem cells. The scaffolds loaded with 50μM Silibinin promoted osteoblast differentiation, which was determined at cellular and molecular levels. Recent studies indicated the role of microRNAs (miRNAs) in osteogenesis and we found that the Silibinin released from scaffolds regulated miRNAs that control the bone morphogenetic protein pathway. Hence, our results suggest the potential for sustained and prolonged release of Silibinin to promote bone formation and, thus, these Alg/Gel-SCN scaffolds may be candidates for bone tissue engineering applications.

Abstract
Repairing large calvarial bone defects remains a challenging task. Previously, it was discovered that that miR-148b, when acting in concert with bone morphogenetic protein 2 (BMP-2), enhanced the osteogenesis of human adipose-derived stem cells (hASCs) and improved calvarial bone healing in nude mice. However, the molecular target of miR-148b remained elusive. Here it is revealed that miR-148b directly targets NOG, whose gene product (noggin) is an antagonist to BMPs and negatively regulates BMP-induced osteogenic differentiation and bone formation. A new Cre/loxP-based baculovirus system was employed to drive prolonged BMP-2 and miR-148b overexpression in hASCs, wherein the BMP-2 overexpression induced noggin expression but the concurrent miR-148b expression downregulated noggin, thus relieving the negative regulatory loop and ameliorating hASC osteogenesis without hindering hASC proliferation or triggering appreciable cytotoxicity. Implantation of the engineered hASCs coexpressing BMP-2 and miR-148b into nude mice enabled substantial repair of critical-size calvarial bone defects (4 mm diameter) at 12 weeks post-transplantation, filling 83% of the defect area, 75% of bone volume and restoring the bone density to 89% of the original bone density. Such superior healing effects indicate the potential of the Cre/loxP-based baculovirus-mediated BMP-2/miR-148b expression for calvarial bone repair. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
Elucidation of the molecular mechanisms that regulate the differentiation of adipose-derived mesenchymal stem cells into osteogenic cells may lead to new methods for bone tissue engineering. We examined the role of miR-26a-5p in the regulation of osteogenic differentiation of mouse adipose-derived mesenchymal stem cells (mADSCs) by using mimics and inhibitors of this microRNA. Our results showed that over-expression of miR-26a-5p inhibited osteogenesis and that suppression of endogenous miR-26a-5p promoted osteogenesis. Four bioinformatics algorithms indicated that the 3'UTR of Wnt5a was a potential target of miR-26a-5p. We confirmed this prediction by use of dual-luciferase reporter assay and GFP/RFP assay. We also examined the molecular mechanisms by which miR-26a-5p regulates osteogenesis. Fura-2AM and Western blot assays after transfection indicated that miR-26a-5p repressed WNT5A, inhibited calcium flux and protein kinase C, and suppressed osteogenic differentiation of mADSCs. By contrast, miR-26a-5p inhibition activated these signal proteins and promoted osteogenic differentiation. Taken together, our results suggest that up-regulation of miR-26a-5p inhibits osteogenic differentiation of mADSCs by directly targeting the 3'UTR of Wnt5a, thereby down-regulating the Wnt/Ca(2+) signaling pathway.

Abstract
As well as acting to fill defects and allow for cell infiltration and proliferation in regenerative medicine, biomaterial scaffolds can also act as carriers for therapeutics, further enhancing their efficacy. Drug and protein delivery on scaffolds have shown potential, however, supraphysiological quantities of therapeutic are often released at the defect site, causing off-target side effects and cytotoxicity. Gene therapy involves the introduction of foreign genes into a cell in order to exert an effect; either replacing a missing gene or modulating expression of a protein. State of the art gene therapy also encompasses manipulation of the transcriptome by harnessing RNA interference (RNAi) therapy. The delivery of nucleic acid nanomedicines on biomaterial scaffolds - gene-activated scaffolds -has shown potential for use in a variety of tissue engineering applications, but as of yet, have not reached clinical use. The current state of the art in terms of biomaterial scaffolds and delivery vector materials for gene therapy is reviewed, and the limitations of current procedures discussed. Future directions in the clinical translation of gene-activated scaffolds are also considered, with a particular focus on bone and cartilage tissue regeneration.

Abstract
Bone grafts are the second most transplanted materials worldwide at a global cost to healthcare systems valued over $30 billion every year. The influence of microRNAs in the regenerative capacity of stem cells offers vast therapeutic potential towards bone grafting; however their efficient delivery to the target site remains a major challenge. This study describes how the functionalisation of porous collagen-nanohydroxyapatite (nHA) scaffolds with miR-133a inhibiting complexes, delivered using non-viral nHA particles, enhanced human mesenchymal stem cell-mediated osteogenesis through the novel focus on a key activator of osteogenesis, Runx2. This study showed enhanced Runx2 and osteocalcin expression, as well as increased alkaline phosphatase activity and calcium deposition, thus demonstrating a further enhanced therapeutic potential of a biomaterial previously optimised for bone repair applications. The promising features of this platform offer potential for a myriad of applications beyond bone repair and tissue engineering, thus presenting a new paradigm for microRNA-based therapeutics.

Int J Biol Macromol 2016; 93:1457-1464.

Abstract
The present study was aimed to synthesize and characterize a bio-composite scaffold containing carboxymethyl cellulose (CMC), zinc doped nano-hydroxyapatite (Zn-nHAp) and ascorbic acid (AC) for bone tissue engineering applications. The fabricated bio-composite scaffold was characterized by SEM, FT-IR and XRD analyses. The ability of scaffold along with a bioactive molecule, microRNA-15b (miR-15b) for osteo-differentiation at cellular and molecular levels was determined using mouse mesenchymal stem cells (mMSCs). miR-15b acts as posttranscriptional gene regulator and regulates osteoblast differentiation. The scaffold and miR-15b were able to promote osteoblast differentiation; when these treatments were combined together on mMSCs, there was an additive effect on promotion of osteoblast differentiation. Thus, it appears that the combination of CMC/Zn-nHAp/AC scaffold with miR-15b would provide more efficient strategy for treating bone related defects and bone regeneration.

Improving the osteogenesis of rat mesenchymal stem cells by chitosan-based-microRNA nanoparticles. Carbohydr Polym 2015; 138:49-58.

Abstract
MicroRNAs (miRNAs) play important roles in the osteogenic differentiation of stem cells. However, the application of miRNA in bone regeneration has been limited by its poor stability, low cellular uptake, and undesired immune response. In this study, chitosan (CS)/tripolyphosphate (TPP)/Hyaluronic Acid (HA) nanoparticles (CTH NPs) were prepared to deliver antimiR-138 to bone marrow mesenchymal stem cells (MSCs). The particle size, polydispersity index, and zeta potential of CTH NPs were related to the weight ratio of CS:TPP:HA. At optimum N/P ratio (20:1), the highest encapsulation efficiency was obtained. Both blank CTH NPs and CTH/antmiR-138 NPs exhibited no cytotoxicity to MSCs. A high transfection efficiency (nearly 70%) and significant enhancement of the osteogenesis of MSCs were observed. Above results demonstrated that CTH NPs was a potential candidate as an efficient non-viral miRNA vector to regulate the osteogenic differentiation of MSCs.

Abstract
Scaffold based bone tissue engineering utilizes a variety of biopolymers in different combinations aiming to deliver optimal properties required for bone regeneration. In the current study, we fabricated bio-composite scaffolds containing chitosan (CS), carboxymethylcellulose (CMC) with varied concentrations of mesoporous wollastonite (m-WS) particles by the freeze drying method. The CS/CMC/m-WS scaffolds were characterized by the SEM, EDS and FT-IR studies. Addition of m-WS particles had no effect on altering the porosity of the scaffolds. m-WS particles at 0.5% concentration in the CS/CMC scaffolds showed significant improvement in the bio-mineralization and protein adsorption properties. Addition of m-WS particles in the CS/CMC scaffolds significantly reduced their swelling and degradation properties. The CS/CMC/m-WS scaffolds also showed cyto-friendly nature to human osteoblastic cells. The osteogenic potential of CS/CMC/m-WS scaffolds was confirmed by calcium deposition and expression of an osteoblast specific microRNA, pre-mir-15b. Thus, the current investigations support the use of CS/CMC/m-WS scaffolds for bone tissue engineering applications.

Abstract
Achieving a successful and well-functioning reconstruction of craniofacial deformities still remains a challenge. As for now, autologous bone grafting remains the gold standard for alveolar cleft reconstruction. However, its aesthetic and functional results often remain unsatisfactory, which carries a long-term psychosocial and medical sequelae. Therefore, searching for novel therapeutic approaches is strongly indicated. With the recent advances in stem cell research, cell-based tissue engineering strategies move from the bench to the patients' bedside. Successful stem cell engineering employs a carefully selected stem cell source, a biodegradable scaffold with osteoconductive and osteoinductive properties, as well as an addition of growth factors or cytokines to enhance osteogenesis. This review highlights recent advances in mesenchymal stem cell tissue engineering, discusses animal models and case reports of stem cell enhanced bone regeneration, as well as ongoing clinical trials.
