Abstract
Bone has a remarkable potential for self-healing and repair, yet several injury types are non-healing even after surgical or non-surgical treatment. Regenerative therapies that induce bone repair or improve the rate of recovery are being intensely investigated. Here, we probed the potential of bone marrow stem cells (BMSCs) engineered with chemically modified mRNAs (modRNA) encoding the hBMP-2 and VEGF-A gene to therapeutically heal bone. Induction of osteogenesis from modRNA-treated BMSCs was confirmed by expression profiles of osteogenic related markers and the presence of mineralization deposits. To test for therapeutic efficacy, a collagen scaffold inoculated with modRNA-treated BMSCs was explored in an in vivo skull defect model. We show that hBMP-2 and VEGF-A modRNAs synergistically drive osteogenic and angiogenic programs resulting in superior healing properties. This study exploits chemically modified mRNAs, together with biomaterials, as a potential approach for the clinical treatment of bone injury and defects.

Abstract
Background Viral vector-based therapeutic gene therapy is a potent strategy to enhance the intrinsic reparative abilities of human orthopaedic tissues. However, clinical application of viral gene transfer remains hindered by detrimental responses in the host against such vectors (immunogenic responses, vector dissemination to nontarget locations). Combining viral gene therapy techniques with tissue engineering procedures may offer strong tools to improve the current systems for applications in vivo. Methods The goal of this work is to provide an overview of the most recent systems exploiting biomaterial technologies and therapeutic viral gene transfer in human orthopaedic regenerative medicine. Results Integration of tissue engineering platforms with viral gene vectors is an active area of research in orthopaedics as a means to overcome the obstacles precluding effective viral gene therapy. Conclusions In light of promising preclinical data that may rapidly expand in a close future, biomaterial-guided viral gene therapy has a strong potential for translation in the field of human orthopaedic regenerative medicine.

Abstract
The aim of this study was to prepare an injectable DNA-loaded nano-calcium phosphate paste that is suitable as bioactive bone substitution material. For this we used the well-known potential of calcium phosphate in bone contact and supplemented it with DNA for the in-situ transfection of BMP-7 and VEGF-A in a critical-size bone defect. 24 New Zealand white rabbits were randomly divided into two groups: One group with BMP-7- and VEGF-A-encoding DNA on calcium phosphate nanoparticles and a control group with calcium phosphate nanoparticles only. The bone defect was created at the proximal medial tibia and filled with the DNA-loaded calcium phosphate paste. As control, a bone defect was filled with the calcium phosphate paste without DNA. The proximal tibia was investigated 2, 4 and 12 weeks after the operation. A histomorphological analysis of the dynamic bone parameters was carried out with the Osteomeasure system. The animals treated with the DNA-loaded calcium phosphate showed a statistically significantly increased bone volume per total volume after 4 weeks in comparison to the control group. Additionally, a statistically significant increase of the trabecular number and the number of osteoblasts per tissue area were observed. These results were confirmed by radiological analysis. The DNA-loaded bone paste led to a significantly faster healing of the critical-size bone defect in the rabbit model after 4 weeks. After 12 weeks, all defects had equally healed in both groups. No difference in the quality of the new bone was found. The injectable DNA-loaded calcium phosphate paste led to a faster and more sustained bone healing and induced an accelerated bone formation after 4 weeks. The material was well integrated into the bone defect and new bone was formed on its surface. The calcium phosphate paste without DNA led to a regular healing of the critical-size bone defect, but the healing was slower than the DNA-loaded paste. Thus, the in-situ transfection with BMP-7 and VEGF-A significantly improved the potential of calcium phosphate as pasty bone substitution material.

Abstract
The transfer of nucleic acids into living cells, i.e. transfection, is a major technique in current molecular biology and medicine. As nucleic acids alone are not able to penetrate the cell membrane, an efficient carrier is needed. Calcium phosphate nanoparticles can serve as carrier due to their biocompatibility, biodegradability and high affinity to nucleic acids like DNA or RNA. Their application was extended here from two-dimensional (2D) to three-dimensional (3D) cell culture models, including co-cultures. Compared to 2D monolayer cell cultures, a 3D culture system represents a more realistic spatial, biochemical and cellular environment. The uptake of fluorescent calcium phosphate nanoparticles (diameter 40-70 nm; cationic) was studied in 2D and 3D cell culture models by confocal laser scanning microscopy. The transfection of eGFP by calcium phosphate nanoparticles was compared in 2D and 3D cell culture, including co-cultures of green fluorescing HeLa-eGFP cells and MG-63 cells in 2D and in 3D models with the red fluorescent protein mCherry. This permitted a cell-specific assessment of the local transfection efficiency. In general, the penetration of nanoparticles into the spheroids was significantly higher than that of a model oligonucleotide carried by Lipofectamine. The transfection efficiency was comparable in 3D cell cultures with 2D cell cultures, but it occurred preferentially at the surface of the spheroids, following the uptake pathway of the nanoparticles. STATEMENT OF SIGNIFICANCE: Three-dimensional cell culture models can serve as a bridge between the in-vitro cell cultures and the in-vivo situation, especially when mass transfer effects have to be considered. This is the case for nanoparticles where the incubation effect in a two-dimensional cell culture strongly differs from a three-dimensional cell culture or a living tissue. We have compared the uptake of nanoparticles and a subsequent transfection of fluorescent proteins in two-dimensional and three-dimensional cell culture models. An elegant model to investigate the transfection in co-cultures was developed using HeLa-eGFP cells (green fluorescent) together with MG-63 cells (non-fluorescent) that were transfected with the red-fluorescing protein mCherry. Thereby, the transfection of both cell types in the co-culture was easily distinguished.

Abstract
The poor and slow healing capacity of tendons requires novel strategies to speed up the tendon repair process. Hence, new and promising developments in tendon tissue engineering have become increasingly relevant. Previously, we have established a tendon progenitor cell line via ectopic expression of the tendon-related basic helix-loop-helix (bHLH) transcription factor Scleraxis (Scx) in human bone marrow mesenchymal stem cells (hMSC-Scx). The aim of this study was to directly compare the characteristics of hMSC-Scx cells to that of primary human tendon stem/progenitors cells (hTSPCs) via assessment of self-renewal and multipotency, gene marker expression profiling, in vitro wound healing assay and three-dimensional cell sheet formation. As expected, hTSPCs were more naive than hMSC-Scx cells because of higher clonogenicity, trilineage differentiation potential, and expression of stem cell markers, as well as higher mRNA levels of several gene factors associated with early tendon development. Interestingly, with regards to wound healing, both cell types demonstrate a comparable speed of scratch closure, as well as migratory velocity and distance in various migration experiments. In the three-dimensional cell sheet model, hMSC-Scx cells and hTSPCs form compact tendinous sheets as histological staining, and transmission electron microscopy shows spindle-shaped cells and collagen type I fibrils with similar average diameter size and distribution. Taken together, hTSPCs exceed hMSC-Scx cells in several characteristics, namely clonogenicity, multipotentiality, gene expression profile and rates of tendon-like sheet formation, whilst in three-dimensional cell sheets, both cell types have comparable in vitro healing potential and collagenous composition of their three-dimensional cell sheets, making both cell types a suitable cell source for tendon tissue engineering and healing.

Abstract
Common scaffold surfaces such as titanium can have side effects; for example, infections, cytotoxicity, impaired osseointegration, or low regeneration rates for bone tissue. These effects lead to poor implant integration or even implant loss. Therefore, bioactive implants are promising instruments in tissue regeneration. Osteoinductive elements-such as growth factors and anti-infectives-support wound healing and bone growth and thereby enable faster osseointegration, even in elderly patients. In this study, titanium surfaces were coated with a poly-(d,l-lactide) (PDLLA) layer containing different concentrations of copolymer-protected gene vectors (COPROGs) to locally provide bone morphogenetic protein-2 (BMP-2) or activated anti-infective agents, such as chlorhexidine gluconate, triclosan, and metronidazole, to prevent peri-implantitis. The coated titanium implants were then loaded with osteoblasts, NIH 3T3 fibroblasts, and human mesenchymal stem cells in 96-well plates. When shielded by COPROGs as a protective layer and resuspended in PDLLA, BMP-2-encoding pDNA at relatively low doses (5.63 µg/implant) induced the local expression of BMP-2. A linear dose dependence, which is common for recombinant growth factors, was not found, probably due to the retention property of the PDLLA surface. PDLLA, in general, successfully retains additional elements, such as osteoconductive growth factors (BMP-2) and anti-infective agents, which was demonstrated using metronidazole, and thus prevents the systemic application of excessive doses. These bioactive implant surfaces that provide the local release of therapeutic gene vectors or anti-infective agents allow the controlled stimulation of the implant and scaffold osseointegration. © 2017 Wiley Periodicals, Inc.

Abstract
Silencing gene expression through a sequence-specific manner can be achieved by small interfering RNAs (siRNAs). The discovery of this process has opened the doors to the development of siRNA therapeutics. Although several preclinical and clinical studies have shown great promise in the treatment of neurological disorders, cancers, dominant disorders, and viral infections with siRNA, siRNA therapy is still gaining ground in musculoskeletal tissue repair and bone regeneration. Here we present a comprehensive review of the literature to summarize different siRNA delivery strategies utilized to enhance bone regeneration. With advancement in understanding the targetable biological pathways involved in bone regeneration and also the rapid progress in siRNA technologies, application of siRNA for bone regeneration has great therapeutic potential. High rates of musculoskeletal injuries and diseases, and their inevitable consequences, impose a huge financial burden on individuals and healthcare systems worldwide.

Abstract
Hereditary gelsolin amyloidosis is an autosomal dominantly inherited amyloid disorder. A point mutation in the GSN gene (G654A being the most common one) results in disturbed calcium binding by the second gelsolin domain (G2). As a result, the folding of G2 is hampered, rendering the mutant plasma gelsolin susceptible to a proteolytic cascade. Consecutive cleavage by furin and MT1-MMP-like proteases generates 8 and 5 kDa amyloidogenic peptides that cause neurological, ophthalmological and dermatological findings. To this day, no specific treatment is available to counter the pathogenesis. Using GSN nanobody 11 as a molecular chaperone, we aimed to protect mutant plasma gelsolin from furin proteolysis in the trans-Golgi network. We report a transgenic, GSN nanobody 11 secreting mouse that was used for crossbreeding with gelsolin amyloidosis mice. Insertion of the therapeutic nanobody gene into the gelsolin amyloidosis mouse genome resulted in improved muscle contractility. X-ray crystal structure determination of the gelsolin G2:Nb11 complex revealed that Nb11 does not directly block the furin cleavage site. We conclude that nanobodies can be used to shield substrates from aberrant proteolysis and this approach might establish a novel therapeutic strategy in amyloid diseases.
