Abstract
Intraosseous bioplasty (IOBP), has been previously described for arthroscopic-assisted treatment of subchondral bone cysts in the proximal tibia associated with early stages of knee osteoarthritis (OA). This technique entails combining bone marrow aspirate concentrate or concentrated platelet-rich plasma with demineralized bone matrix as a bone substitute before injecting into a subchondral bone defect under fluoroscopic guidance. The principles of IOBP as a procedure that combines core decompression with biologic bone substitute augmentation can be extended to treat subchondral bone marrow lesions such as acetabular and femoral cysts in degenerative hip OA. Intraosseous bioplasty of the hip, in particular the acetabulum, when done using this technique, is a useful alternative that can be beneficial in treating young patients with early hip arthritis to achieve successful outcomes while delaying more invasive procedures. The Technical Note described here presents a step-by-step approach, including tips and pearls for arthroscopic-assisted IOBP with decompression of the subchondral cyst in the acetabulum followed by bone substitute injection under fluoroscopic guidance. We believe this method is a safe and reproducible way to treat subchondral defects in young patients with signs of early osteoarthritis of the hip joint.

Abstract
Extracellular matrix (ECM)-ornamented biomaterials have attracted attention due to their high potential to improve the biofunctionality of original materials. It is thought that ECM with a bone mimetic microenvironment generated by the specific induction of osteoblasts would be more beneficial for bone regeneration than a regular ECM. In this study, we developed an osteogenic and mineralized ECM construct (Os/M-ECM-SIS) under the guidance of osteoblasts on a small intestinal submucosa (SIS) scaffold cotreated with icariin and calcium. The generated Os/M-ECM-SIS scaffolds exhibited similar morphology and inorganic components as natural bone and higher mechanical strength than ECM-SIS. Cell adhesion, proliferation, and differentiation of osteoblasts and fibroblasts were also enhanced in the cells cultured on the Os/M-ECM-SIS scaffolds. The Os/M-ECM-SIS scaffolds even promoted transdifferentiation of fibroblasts with an upregulation of osteogenic differentiation markers. In a calvarial defect model, new bone formation was greatly enhanced in defects implanted with the Os/M-ECM-SIS scaffolds compared with ECM-SIS scaffolds. Further study showed that the Os/M-ECM-SIS scaffolds promoted bone regeneration in vitro and in vivo via the Bmp/Smad-signaling pathway. Thus, this work proposes a valuable method for generating a mineralized bone mimetic scaffold with SIS as off-the-shelf bone graft substitute that provides an excellent osteogenic microenvironment, making it suitable for application in bone tissue engineering.

Abstract
Calcium phosphate cements (CPCs) are synthetic bioactive cements widely used as hard tissue substitutes. Critical limitations of use include their poor mechanical properties and poor anti-washout behaviour. To address those limitations, we combined CPC with genetically engineered elastin-like polypeptides (ELPs). We investigated the effect of the ELPs on the physical properties and biocompatibility of CPC by testing ELP/CPC composites with various liquid/powder ratios. Our results show that the addition of ELPs improved the mechanical properties of the CPC, including the microhardness, compressive strength, and washout resistance. The biocompatibility of ELP/CPC composites was also comparable to that of the CPC alone. However, supplementing CPC with ELPs functionalized with octaglutamate as a hydroxyapatite binding peptide increased the setting time of the cement. With further design and modification of our biomolecules and composites, our research will lead to products with diverse applications in biology and medicine.

Abstract
Tissue engineering and regenerative medicine has been providing exciting technologies for the development of functional substitutes aimed to repair and regenerate damaged tissues and organs. Inspired by the hierarchical nature of bone, nanostructured biomaterials are gaining a singular attention for tissue engineering, owing their ability to promote cell adhesion and proliferation, and hence new bone growth, compared with conventional microsized materials. Of particular interest are nanocomposites involving biopolymeric matrices and bioactive nanosized fillers. Biodegradability, high mechanical strength, and osteointegration and formation of ligamentous tissue are properties required for such materials. Biopolymers are advantageous due to their similarities with extracellular matrices, specific degradation rates, and good biological performance. By its turn, calcium phosphates possess favorable osteoconductivity, resorbability, and biocompatibility. Herein, an overview on the available natural polymer/calcium phosphate nanocomposite materials, their design, and properties is presented. Scaffolds, hydrogels, and fibers as biomimetic strategies for tissue engineering, and processing methodologies are described. The specific biological properties of the nanocomposites, as well as their interaction with cells, including the use of bioactive molecules, are highlighted. Nanocomposites in vivo studies using animal models are also reviewed and discussed.

Abstract
Calcium phosphates (CaP) are considered as biomaterials of choice for the treatment of critical-sized bone defects. Novel injectable CaP materials integrating poly(epsilon-lysine) generation 3 dendrons tethered with phosphoserine were obtained by sol-gel synthesis. This type of dendron was integrated to mimic the biochemical structure of noncollagenous proteins present in the forming osteoids during bone repair. Sol-gel synthesis was coupled with a dialysis process able to equilibrate the materials at a physiological pH value. Fourier transform infrared spectroscopy (FTIR) showed the successful retention of the dendrons after gel dialysis, whereas X-ray diffraction analysis demonstrated both the pH-tuned formation of a hydroxyapatite crystalline phase within the gel and the complete removal of ammonium nitrate deriving from the sol-gel reaction solvent. Scanning electron microscopy images confirmed the presence of crystalline domains in gels synthesized at pH 9.0. Injectability tests showed that the optimized formulations fulfilled the rheological properties required to minimally invasive surgical procedures. Cytotoxicity tests on osteoblast-like MG-63 cells as well as morphology and viability studies showed that the dendrons induced a significantly higher level of cell proliferation at early incubation time. Differentiation of the cell was also clearly enhanced at longer incubation time as demonstrated by both alkaline phosphatase activity and expression of typical markers. Altogether, the data from this work indicate the clinical potential of the osteoid-mimicking CaP cements in minimally invasive bone surgery.

Abstract
BACKGROUND CONTEXT There is no comparative study of the in vitro and in vivo osteogenic potential of iliac bone chips (autogenous iliac cancellous bone chips) compared with bone dusts generated during the decortication process with a high-speed burr in spine fracture or fusion surgery. PURPOSE To compare the osteogenic potential of three sizes of bone dusts with iliac bone chips and to determine whether bone dusts can be used as a bone graft substitute. STUDY DESIGN In vitro and in vivo study. METHODS Bone chips were harvested from the posterior superior iliac spine and bone dusts from the vertebrae of 15 patients who underwent spinal fracture surgery. Bone dust was divided into three groups: small (3 mm), middle (4 mm), and large (5 mm) according to the size of the burr tip. A comparison was made using a cell proliferation assay, alkaline phosphatase (ALP) activity, the degree of mineralization in an in vitro model, and radiographic and histologic studies (the change of absorbable area and tissue density) after implantation of the various materials into back muscles of nude mice. RESULTS Although all three bone dust groups were less active with regard to cell proliferation, ALP activity, and the degree of mineralization, than were bone chips, they still exhibited osteogenic potential. Furthermore, there was no significant difference among the three bone dust groups. The three bone dust groups did show greater absorbable area and change of the tissue density than did the iliac bone chip group. Again, there was no significant difference among the three bone dust groups in this regard. Histologically, specimens from the bone dust groups had a higher osteoclast cell number than specimens from the iliac bone chip group. CONCLUSIONS The osteogenic potential of bone dusts is lower than that of iliac bone chips, and the absorption speed of bone dusts in vivo is faster than that of iliac bone chips. The increased resorption speed appeared to result from an increase in osteoclast cell number. Therefore, caution needs to be used when surgeons employ bone dust as a bone graft substitute.

Abstract
Natural polymers, because of their biocompatibility, availability, and physico-chemical properties have been the materials of choice for the fabrication of injectable hydrogels for regenerative medicine. In particular, they are appealing materials for delivery systems and provide sustained and controlled release of drugs, proteins, gene, cells, and other active biomolecules immobilized.In this work, the use of hydrogels obtained from natural source polymers as cell delivery systems is discussed. These materials were investigated for the repair of cartilage, bone, adipose tissue, intervertebral disc, neural, and cardiac tissue. Papers from the last ten years were considered, with a particular focus on the advances of the last five years. A critical discussion is centered on new perspectives and challenges in the regeneration of specific tissues, with the aim of highlighting the limits of current systems and possible future advancements.

Abstract
The controlled delivery of growth factors and cells within biomaterial carriers can enhance and accelerate functional bone formation. The carrier system can be designed with pre-programmed release kinetics to deliver bioactive molecules in a localized, spatiotemporal manner most similar to the natural wound healing process. The carrier can also act as an extracellular matrix-mimicking substrate for promoting osteoprogenitor cellular infiltration and proliferation for integrative tissue repair. This review discusses the role of various regenerative factors involved in bone healing and their appropriate combinations with different delivery systems for augmenting bone regeneration. The general requirements of protein, cell and gene therapy are described, with elaboration on how the selection of materials, configurations and processing affects growth factor and cell delivery and regenerative efficacy in both in vitro and in vivo applications for bone tissue engineering.

Abstract
The vast majority of materials used in bone tissue engineering and regenerative medicine are based on calcium phosphates due to their similarity with the mineral phase of natural bone. Among them, calcium phosphate cements, which are composed of a powder and a liquid that are mixed to obtain a moldable paste, are widely used. These calcium phosphate cement pastes can be injected using minimally invasive surgery and adapt to the shape of the defect, resulting in an entangled network of calcium phosphate crystals. Adding an organic phase to the calcium phosphate cement formulation is a very powerful strategy to enhance some of the properties of these materials. Adding some water-soluble biocompatible polymers in the calcium phosphate cement liquid or powder phase improves physicochemical and mechanical properties, such as injectability, cohesion, and toughness. Moreover, adding specific polymers can enhance the biological response and the resorption rate of the material. The goal of this study is to overview the most relevant advances in this field, focusing on the different types of polymers that have been used to enhance specific calcium phosphate cement properties.
