Abstract
![]()
The
ongoing research to improve the clinical outcome of titanium
implants has resulted in the implemetation of multiple approches to
deliver osteogenic growth factors accelerating and sustaining osseointegration.
Here we show the presentation of human bone morphogenetic protein
7 (BMP-7) adsorbed to titanium discs coated with poly(ethyl acrylate)
(PEA). We have previously shown that PEA promotes fibronectin organization
into nanonetworks exposing integrin- and growth-factor-binding domains,
allowing a synergistic interaction at the integrin/growth factor receptor
level. Here, titanium discs were coated with PEA and fibronectin and
then decorated with ng/mL doses of BMP-7. Human mesenchymal stem cells
were used to investigate cellular responses on these functionalized
microenvironments. Cell adhesion, proliferation, and mineralization,
as well as osteogenic markers expression (osteopontin and osteocalcin)
revealed the ability of the system to be more potent in osteodifferentiation
of the mesenchymal cells than combinations of titanium and BMP-7 in
absence of PEA coatings. This work represents a novel strategy to
improve the biological activity of titanium implants with BMP-7.

Abstract
Porous titanium (Ti) scaffolds are widely used for bone repair because of their good biocompatibility, mechanical properties, and corrosion resistance. However, pristine Ti scaffolds are bioinert and unable to induce bone regeneration. In this study, chitosan coated bovine serum albumin nanoparticles (CBSA NPs) and oxidized alginate (OSA) were in a layer-by-layer (LbL) manner on Ti scaffolds. The LbL film possessed micro/nano-hierarchical architectures, has the features of nanostructures, and possesses abundant functional groups from CBSA NPs and OSA to improve the surface biocompatibility and biofunctionality of Ti scaffolds. These groups provide active sites for stable and efficient immobilization of bone morphogenic protein-2 (BMP2) through chemical and physical interactions without compromising its bioactivity. The synergistic effect of the hierarchical structure of assembled films and immobilized BMP2 on the scaffold improves cell adhesion, proliferation, and induces osteogenic differentiation of bone marrow stromal cells in vitro. Moreover, this modification also enhances ectopic bone formation bone. Furthermore, grafting of vancomycin on OSA resulted in good antibacterial activity of Ti scaffolds for prevention of infection during the bone healing process. In summary, this NPs-assembling method is convenient and effective to produce nanostructures and to load growth factors and antibacterial agents into Ti scaffolds for bone tissue engineering. © 2017 Wiley Periodicals, Inc.

Abstract
Chronic and acute osteochondral defects as a result of osteoarthritis and trauma present a common and serious clinical problem due to the tissue's inherent complexity and poor regenerative capacity. In addition, cells within the osteochondral tissue are in intimate contact with a 3D nanostructured extracellular matrix composed of numerous bioactive organic and inorganic components. As an emerging manufacturing technique, 3D printing offers great precision and control over the microarchitecture, shape and composition of tissue scaffolds. Therefore, the objective of this study is to develop a biomimetic 3D printed nanocomposite scaffold with integrated differentiation cues for improved osteochondral tissue regeneration. Through the combination of novel nano-inks composed of organic and inorganic bioactive factors and advanced 3D printing, we have successfully fabricated a series of novel constructs which closely mimic the native 3D extracellular environment with hierarchical nanoroughness, microstructure and spatiotemporal bioactive cues. Our results illustrate several key characteristics of the 3D printed nanocomposite scaffold to include improved mechanical properties as well as excellent cytocompatibility for enhanced human bone marrow-derived mesenchymal stem cell adhesion, proliferation, and osteochondral differentiation in vitro. The present work further illustrates the effectiveness of the scaffolds developed here as a promising and highly tunable platform for osteochondral tissue regeneration.

Abstract
Many studies have demonstrated the possibility to regulate cellular behavior by manipulating the specific characteristics of biomaterials including the physical features and chemical properties. To investigate the synergistic effect of chemical factors and surface topography on the growth behavior of mesenchymal stem cells (MSCs), bone morphorgenic protein 2 (BMP2) was immobilized onto porous alumina substrates with different pore sizes. The BMP2-immobilized alumina substrates were characterized with scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Growth behavior and osteogenic differentiation of MSCs cultured on the different substrates were investigated. Cell adhesion and morphological changes were observed with SEM, and the results showed that the BMP2-immobilized alumina substrate was able to promote adhesion and spreading of MSCs. MTT assay and immunofluorescence staining of integrin β1 revealed that the BMP2-immobilized alumina substrates were favorable for cell growth. To evaluate the differentiation of MSCs, osteoblastic differentiation markers, such as alkaline phosphatase (ALP) activity and mineralization, were investigated. Compared with those of untreated alumina substrates, significantly higher ALP activities and mineralization were detected in cells cultured on BMP2-immobilized alumina substrates. The results suggested that surface functionalization of nanoporous alumina substrates with BMP2 was beneficial for cell growth and osteogenic differentiation. With the approach of immobilizing growth factors onto material substrates, it provided a new insight to exploit novel biofunctional materials for tissue engineering.

Abstract
The polymer-controlled and bioinspired precipitation of inorganic minerals from aqueous solution at near-ambient or physiological conditions avoiding high temperatures or organic solvents is a key research area in materials science. Polymer-controlled mineralization has been studied as a model for biomineralization and for the synthesis of (bioinspired and biocompatible) hybrid materials for a virtually unlimited number of applications. Calcium phosphate mineralization is of particular interest for bone and dental repair. Numerous studies have therefore addressed the mineralization of calcium phosphate using a wide variety of low- and high-molecular-weight additives. In spite of the growing interest and increasing number of experimental and theoretical data, the mechanisms of polymer-controlled calcium phosphate mineralization are not entirely clear to date, although the field has made significant progress in the last years. A set of elegant experiments and calculations has shed light on some details of mineral formation, but it is currently not possible to preprogram a mineralization reaction to yield a desired product for a specific application. The current article therefore summarizes and discusses the influence of (macro)molecular entities such as polymers, peptides, proteins and gels on biomimetic calcium phosphate mineralization from aqueous solution. It focuses on strategies to tune the kinetics, morphologies, final dimensions and crystal phases of calcium phosphate, as well as on mechanistic considerations.
