Toward osteomimetic formation of calcium phosphate coatings with carbonated hydroxyapatite. BIOMATERIALS ADVANCES 2023; 149:213403. [PMID: 37075660 DOI: 10.1016/j.bioadv.2023.213403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 03/07/2023] [Accepted: 03/22/2023] [Indexed: 04/21/2023]
Abstract
Biomimetic production of coatings on various types of scaffolds is based mainly on simulated body fluid precipitation (SBF) of apatites, or, if the HCO3- is present, carbonated apatites. Recently, we proposed formation of calcium phosphates (CaP) precipitates by alkaline phosphatase (ALP) hydrolysing glycerophosphate in presence of calcium ions as an alternative to SBF. Since apatites synthesized in bone by the ALP activity contain carbonate anions, it was tempting to investigate whether the phosphatase method could be advanced into osteomimetic one. Therefore, taking example from the SBF studies, phosphatase incubation medium was enriched with carbonate ions at 4.2 and 27 mM concentration. X-ray diffraction of the precipitates disclosed peaks typical for hydroxyapatite (HAP). FTIR analysis showed that at both concentration of carbonate ions, apatites underwent both B and A substitution, more extensive at higher concentration. Thus, osteomimetic approach produced carbonated hydroxyapatites of the type encountered in bone tissue even at HCO3- concentration as low as 4.2 mM. Composite plates made of poly(ε-caprolactone) and mixture of β-tricalcium phosphate and hydroxyapatite at mass ratio of 1:0.5:0.5, respectively, were covered by CaP coatings, i.e., CaP-0, CaP-4.2, CaP-27, by incubation in phosphatase medium containing 0, 4.2 or 27 mM of NaHCO3, respectively. Pristine or coated PCL50 plates were used to study release of calcium and adsorption/desorption of proteins, or seeded with human bone marrow mesenchymal stem cells (hMSC) for study of cell adhesion, spreading and osteogenic differentiation. Introduction of carbonate into the CaP coatings significantly increased release of Ca2+ in a carbonate concentration-dependent manner; the release was up to 4 times higher, when compared to CaP-0 coating, and reached 0.41 ± 0.01 mM for CaP-27 after first 24 h. Coating CaP-4.2 yielded significantly higher adsorption of bovine serum albumin and cytochrome C than CaP-0. All of the CaP coatings improved significantly hMSC adhesion, however, only CaP-4.2 provided 2 times higher cell number than PCL50 after 2 weeks of culture. Interestingly, ALP activity calculated per cell number was the highest on pristine plates, presumably because hMSC differentiate preferentially into osteoblasts at lower seeding densities. It appears, therefore, that the osteomimetic approach may be useful for production of carbonated hydroxyapatite coatings, but requires further studies and replacing intestinal phosphatase used in this work with one originating from bone.

Effect of calcium stearate as a lubricant and catalyst on the thermal degradation of poly(3-hydroxybutyrate). Int J Biol Macromol 2021; 190:780-791.

Abstract
Poly(3-hydroxybutyrate) (PHB) is a promising substitute to petroleum-based polymers in packaging and biomedical applications provided that its melt processability and degradability are improved. A new method to control the properties of PHB by using cheap calcium stearate (CS) as a lubricant and decomposition catalyst in melt-mixed PHB-CS compounds was first used. CS is composed of a metallic cation, which promotes PHB degradation, and a hydrophobic anion that improves the compatibility with PHB and processability. An environmentally friendly melt mixing technique was employed to obtain the PHB-CS compounds. Incorporation of 0.5 or 5 wt% CS reduced the melt viscosity and molecular weight of PHB, decreased the melting temperature with up to 5 °C, the crystallization temperature with more than 25 °C, and the degradation temperature with 15 and 40 °C, respectively. In small amounts (0.05 wt%), CS improved the processability and mechanical properties of PHB. In higher amount (0.5 wt%), CS slightly improved the Young's modulus, reduced the tensile strength and enhanced degradation. A better control of thermal and mechanical properties of PHB is, thus, possible by using different CS amount and processing conditions. These results are relevant for PHB application in the context of the global transition to biodegradable packaging.

Abstract
The present work reported the preparation of biocomposites based on poly(3-hydroxybutyrate) (PHB), plasticizer, and bacterial cellulose (BC) by melt processing and their testing by means of thermal properties (DSC), water absorption, and in vitro degradation. The surface of the biocomposites was analyzed via atomic force microscopy (AFM). In vitro degradation of the biocomposites was evaluated by weight loss and thermal properties (DSC) assessment after the immersion of the specimens in phosphate-buffered saline solution (PBS of pH 7.4) over 20 days. The results showed that the BC can reduce the PHB crystallinity and promote its degradation under PBS medium. Moreover, it was found that the water absorption increased as the percentage of BC increased.

Abstract
Numerous surgical procedures are daily performed worldwide to replace and repair damaged tissue. Tissue engineering is the field devoted to the regeneration of damaged tissue through the incorporation of cells in biocompatible and biodegradable porous constructs, known as scaffolds. The scaffolds act as host biomaterials of the incubating cells, guiding their attachment, growth, differentiation, proliferation, phenotype, and migration for the development of new tissue. Furthermore, cellular behavior and fate are bound to the biodegradation of the scaffold during tissue generation. This article provides a critical appraisal of how key biomaterial scaffold parameters, such as structure architecture, biochemistry, mechanical behavior, and biodegradability, impart the needed morphological, structural, and biochemical cues for eliciting cell behavior in various tissue engineering applications. Particular emphasis is given on specific scaffold attributes pertaining to skin and brain tissue generation, where further progress is needed (skin) or the research is at a relatively primitive stage (brain), and the enumeration of some of the most important challenges regarding scaffold constructs for tissue engineering.

Abstract
Nowadays, the assessment of the mechanical competence of tissue engineering scaffolds based on computer simulations is a well-accepted technology. Typically, such simulations are performed by means of the Finite Element (FE) method, with the underlying structural model being created based on micro-computed tomography (microCT). Here, this analysis modality is applied to a new, ternary composite, consisting of PHBV, i.e. poly(3-hydroxybutyrate-co-3-hydroxyvalerate), PLGA, i.e. poly(lactic-co-glycolide), as well as of TCP, i.e. tricalcium phosphate hydrate. The studied scaffold structure is made up by fibers of this new composite material, manufactured by means of the rapid prototyping method. The data collected from microCT is utilized for adequately defining the mechanical properties of the FE model. In particular, the three-dimensional field of grey values is interpreted in terms of the underlying field of attenuation coefficients, taking into account the photon energy employed in microCT imaging, eventually allowing for calculation of the three-dimensionally distributed, voxel-specific composition of the studied material. For the sake of keeping the FE simulations as efficient as possible, groups of voxels are combined into one finite element; the grey value of the latter is obtained by volume averaging. Employing a two-step micromechanical homogenization scheme, the experimentally accessible stiffness of the three constituents (PHBV, PLGA, and TCP) is then, finite element by finite element, upscaled to the composition-dependent stiffness of the composite material. The plausibility and adequacy of the FE model is demonstrated by simulating the effects of uniaxial compression on the scaffold structure, in terms of resulting stress and strain fields, highlighting the importance of the fiber junctions (as they are the mechanically most stressed regions), and that neglecting the material heterogeneity would lead to a potentially significant underestimation of stresses and strains. Finally, a comparison is made of the employed analysis modality of microCT data with a previously pursued, simplified analysis strategy, highlighting the conceptual superiority of the former, and pointing out the application limits of the latter.

Abstract
Porous nanocomposite of hydroxyapatite/poly(lactide-co-glycolide) (HA/PLGA) is conventionally used in bone tissue engineering but seldom in load-bearing orthopedic applications due to poor mechanical property. This study aimed to fabricate an injectable ternary composite by incorporating different contents of poly(glycolide) (PGA) fibers (0, 30, 50 and 70wt%) into the nanocomposite HA/PLGA matrix as reinforcing fillers for bone tissue repair. The fibers were obtained from melt-spinning and fiber diameter ranged from 70nm to 191μm. The injectability, mechanical strength, solidification rate and cytotoxicity of injectable composites were characterized. All composites achieved the acceptable injectability under an injection force of 100N. The mechanical properties of composites were gradually enhanced by increasing PGA fiber contents. The compression strength of composite with 70wt% content of PGA fibers was up to 31.1MPa, which was four times stronger than that of composite without PGA fibers. In the solidification rate analysis, the compression strength of composites with 50 or 70wt% PGA fibers in immersion time of only 45min was similar to that of composite without fibers in immersion time of 4-5h. The MTT test showed that exceeding 70% cells could survive in the fourfold dilution of extract, and its cytotoxicity focused on the first 4h after immersing. This study have revealed that the PGA fiber-reinforced HA/PLGA composite is a promising candidate for orthopedic applications.

Abstract
The current investigation was aimed at identifying the role of mesoporous wollastonite particles on the healing of rat tibial bone defect. The bone defect was created with a 3-mm-diameter dental drill, and it was filled with mesoporous wollastonite particles. After second and fourth weeks of filling treatments, it was found that mesoporous wollastonite particles promoted bone formation as evidenced by X-ray, histological, scanning electron microscope, and energy-dispersive spectra studies. X-ray study showed the closure of drill hole as seen by high-dense radio-opacity image. Histological analysis depicted the deposition of collagen in the bone defect area in response to mesoporous wollastonite particles’ treatment. Scanning electron microscope–energy-dispersive spectra analyses of the sectioned implants also identified the deposition of apatite by these particles. Thus, our results suggested that mesoporous wollastonite particles have bioactive properties, and they can be used as a suitable filling material for promotion of bone formation in vivo.
