Witt R, Weigand A, Boos AM, et al., 2017, Mesenchymal stem cells and myoblast differentiation under HGF and IGF-1 stimulation for 3D skeletal muscle tissue engineering, BMC Cell Biology, Vol: 18, ISSN: 1471-2121
BackgroundVolumetric muscle loss caused by trauma or after tumour surgery exceeds the natural regeneration capacity of skeletal muscle. Hence, the future goal of tissue engineering (TE) is the replacement and repair of lost muscle tissue by newly generating skeletal muscle combining different cell sources, such as myoblasts and mesenchymal stem cells (MSCs), within a three-dimensional matrix. Latest research showed that seeding skeletal muscle cells on aligned constructs enhance the formation of myotubes as well as cell alignment and may provide a further step towards the clinical application of engineered skeletal muscle.In this study the myogenic differentiation potential of MSCs upon co-cultivation with myoblasts and under stimulation with hepatocyte growth factor (HGF) and insulin-like growth factor-1 (IGF-1) was evaluated. We further analysed the behaviour of MSC-myoblast co-cultures in different 3D matrices.ResultsPrimary rat myoblasts and rat MSCs were mono- and co-cultivated for 2, 7 or 14 days. The effect of different concentrations of HGF and IGF-1 alone, as well as in combination, on myogenic differentiation was analysed using microscopy, multicolour flow cytometry and real-time PCR. Furthermore, the influence of different three-dimensional culture models, such as fibrin, fibrin-collagen-I gels and parallel aligned electrospun poly-ε-caprolacton collagen-I nanofibers, on myogenic differentiation was analysed. MSCs could be successfully differentiated into the myogenic lineage both in mono- and in co-cultures independent of HGF and IGF-1 stimulation by expressing desmin, myocyte enhancer factor 2, myosin heavy chain 2 and alpha-sarcomeric actinin. An increased expression of different myogenic key markers could be observed under HGF and IGF-1 stimulation. Even though, stimulation with HGF/IGF-1 does not seem essential for sufficient myogenic differentiation. Three-dimensional cultivation in fibrin-collagen-I gels induced higher levels of myogenic di

Souza MT, Tansaz S, Zanotto ED, et al., 2017, Bioactive glass fiber-reinforced PGS matrix composites for cartilage regeneration, Materials, Vol: 10, ISSN: 1996-1944
Poly(glycerol sebacate) (PGS) is an elastomeric polymer which is attracting increasing interest for biomedical applications, including cartilage regeneration. However, its limited mechanical properties and possible negative effects of its degradation byproducts restrict PGS for in vivo application. In this study, a novel PGS–bioactive glass fiber (F18)-reinforced composite was developed and characterized. PGS-based reinforced scaffolds were fabricated via salt leaching and characterized regarding their mechanical properties, degradation, and bioactivity in contact with simulated body fluid. Results indicated that the incorporation of silicate-based bioactive glass fibers could double the composite tensile strength, tailor the polymer degradability, and improve the scaffold bioactivity.

© 2017 Trans Tech Publications, Switzerland. An area of major interest in biomedical engineering is currently the development of improved materials for medical implants. Research efforts are being focused on the investigation of surface modification methods for metallic prostheses due to the fundamental bioinert character of these materials and the possible ion release from their surfaces, which could potentially induce the interfacial loosening of devices after implantation. Electron beam (EB) structuring is a novel technique to control the surface topography in metals. Electrophoretic deposition (EPD) offers the feasibility to deposit at room temperature a variety of materials on conductive substrates from colloidal suspensions under electric fields. In this work single layers of chitosan composite coatings containing titania nanoparticles (n-TiO2) were deposit by EPD on electron beam (EB) structured Ti6Al4V titanium alloy. Surface structures were designed following different criteria in order to develop specific topography on the Ti6Al4V substrate. n-TiO2 particles were used as a model particle in order to demonstrate the versatility of the proposed technique for achieving homogenous chitosan based coatings on structured surfaces. A linear relation between EPD time and deposition yield on different patterned Ti6Al4V surfaces was determined under constant voltage conditions, obtaining homogeneous EPD coatings which replicate the 3D structure (pattern) of the substrate surface. The present results show that a combination of both techniques can be considered a promising surface modification approach for metallic implants, which should lead to improved interaction between the implant surface and the biological environment for orthopaedic applications.

© The Royal Society of Chemistry 2017. In the last few decades bioactive glasses (BGs) have been widely considered for bone tissue engineering applications due to their bioactivity and their osteogenic effects. The available scientific evidence suggests that ionic dissolution products (at a critical concentration) released during the degradation of the BG matrix induce osteogenic gene expression hence stimulating the bone regeneration process. Moreover, adding bioactive metallic ions (e.g. boron, copper, cobalt, lithium silver, zinc and strontium) to silicate as well as to phosphate and borate glasses has emerged as a promising route to develop novel BG formulations with specific therapeutic functionalities, including antibacterial, angiogenic, osteogenic and wound healing. The degradation behaviour of BGs can be tailored by adjusting the glass chemistry, making these biomaterials suitable carrier systems for controlled therapeutic ion release. This book chapter summarizes the fundamental aspects of the effect of ionic dissolution products released from BGs on osteogenesis and angiogenesis, also discussing novel BG compositions containing inorganic therapeutic agents. In vitro cellular as well as in vivo responses to specific therapeutic ions are discussed.
Naseri S, Boccaccini AR, Nazhat SN, 2017, Chapter 10: Bioactive Glass Particulate-incorporated Polymer Composites, RSC Smart Materials, Pages: 236-256
© The Royal Society of Chemistry 2017. Bioactive glasses can potentially be used in combination with polymers in order to create a new complex of enhanced bioactivity, biocompatibility, and mechanical and degradation properties for biomedical applications. There are various processing routes to fabricate particulate bioactive glass fillers composites (dense or porous). Each fabrication route has its own advantages and disadvantages, and the best fabrication route is determined depending on the materials used and the desired final application. In this chapter, the main particulate bioactive glass-incorporated polymer composite fabrication techniques are presented, along with their associated pros and cons. Additionally, the properties of the various composites for tissue engineering and biomedical applications are discussed.

Miguez-Pacheco V, Gorustovich AA, Boccaccini AR, et al., 2017, Chapter 15: Bioactive Glasses for Soft Tissue Engineering Applications, RSC Smart Materials, Pages: 336-361
© The Royal Society of Chemistry 2017. In the last few years the usage of bioactive glasses as scaffolds for soft tissue engineering has been investigated more thoroughly. The reason for the boost in interest is the attractive properties bioactive glasses offer, including bioactivity as well as antibacterial, angiogenic and hemostatic properties. So far, most research efforts have focused on applications for repairing skin and nerve tissue although there have been interesting developments in other fields including lung and intestine, which could potentially benefit a large group of patients. Three review articles on this topic have been published, so this chapter will mainly focus on the latest relevant findings. A great number of patents have been registered for the use of bioactive glass for hard tissue engineering. Recently, however, patents have been filed detailing the use of bioactive glass for soft tissue engineering applications which open the way to marketing bioactive glasses for soft tissue repair. The angiogenic effect of bioactive glasses and their dissolution products is of great interest for tissue engineering applications in general and in particular for soft tissue regeneration and repair. The third part of this chapter will detail the latest research on these angiogenic properties of bioactive glasses.
