Effects of Daidzein, Tempeh, and a Probiotic Digested in an Artificial Gastrointestinal Tract on Calcium Deposition in Human Osteoblast-like Saos-2 Cells. Int J Mol Sci 2024; 25:1008. [PMID: 38256081 PMCID: PMC10815870 DOI: 10.3390/ijms25021008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 12/27/2023] [Accepted: 01/11/2024] [Indexed: 01/24/2024] Open
Abstract
Adequate calcium intake is crucial for the prevention and treatment of bone-related issues. Developing a nutritional source of readily bioavailable calcium is particularly significant for individuals deficient in this essential element and at risk of developing osteoporosis. This research aimed to evaluate the impact of tempeh (T), daidzein (D), and Lactobacillus acidophilus (LA) within a simulated intestinal environment consisting of Caco-2 epithelial and Saos-2 cells, focusing on their implications for bone mineralization mechanisms. In the initial phase, calcium bioaccessibility from calcium citrate (CaCt), LA, D, the daidzein combination D-CaCt-LA (D1:1:1), and the tempeh combination T-CaCt-LA (T1:1:1) was assessed through digestion simulation. The calcium content of both untreated and digested samples was determined using atomic absorption spectrometry (AAS). In the subsequent stage, the digested samples were used to induce intestinal absorption in differentiated enterocyte-like Caco-2 cells. The permeable fractions were then evaluated in a culture of osteoblast-like Saos-2 cells. Preliminary cellular experiments employed the MTT assay to assess cytotoxicity. The results indicated that the analyzed products did not influence the deposition of extracellular calcium in Saos-2 cells cultured without mineralization stimulators. The combined formulations of permeable fractions of digested CaCt, LA, D, and T demonstrated the capacity to enhance the proliferation of Saos-2 cells. In Saos-2 cells, D, D1:1:1, and LA showed no discernible impact on intracellular calcium accumulation, whereas T and T1:1:1 reduced the calcium deposits. Additionally, mRNA transcripts and alkaline phosphatase (ALP) activity levels in Saos-2 cells cultured without mineralization induction were unaffected by the analyzed products. An examination of the products revealed no discernible effect on ALP activity or mRNA expression during Saos-2 cell differentiation. Our findings suggest that tempeh, daidzein, and L. acidophilus did not positively impact cellular calcium deposition in Saos-2 cells. However, tempeh, daidzein and its combination, and L. acidophilus might enhance the process of osteogenic differentiation in Saos-2 cells. Nevertheless, this study did not identify any synergistic impact on calcium deposition and the process of osteogenic differentiation in Saos-2 cells of isoflavones and probiotics.

Abstract
Calcium phosphate (CaP)-based bioceramics are the most widely used synthetic biomaterials for reconstructing damaged bone. Accompanied by bone healing process, implanted materials are gradually degraded while bone ultimately returns to its original geometry and function. In this progress report, we reviewed the complex and tight relationship between the bone healing response and CaP-based biomaterials, with the emphasis on the in vivo degradation mechanisms of such material and their osteoinductive properties mediated by immune responses, osteoclastogenesis and osteoblasts. A deep understanding of the interaction between biological healing process and biomaterials will optimize the design of CaP-based biomaterials, and further translate into effective strategies for biomaterials customization.

Acta Biomater 2022; 140:163-177. [PMID: 34875356 DOI: 10.1016/j.actbio.2021.11.049] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 11/24/2021] [Accepted: 11/30/2021] [Indexed: 12/21/2022]
Abstract
The development of bone-like tissues in vitro that exhibit key features similar to those in vivo is needed to produce tissue models for drug screening and the study of bone physiology and disease pathogenesis. Extracellular matrix (ECM) is a predominant component of bone in vivo; however, as ECM assembly is sub-optimal in vitro, current bone tissue engineering approaches are limited by an imbalance in ECM-to-cell ratio. We amplified the deposition of osteoblastic ECM by supplementing dextran sulfate (DxS) into osteogenically induced cultures of human mesenchymal stem cells (MSCs). DxS, previously implicated to act as a macromolecular crowder, was recently demonstrated to aggregate and co-precipitate major ECM components, including collagen type I, thereby amplifying its deposition. This effect was re-confirmed for MSC cultures undergoing osteogenic induction, where DxS supplementation augmented collagen type I deposition, accompanied by extracellular osteocalcin accumulation. The resulting differentiated osteoblasts exhibited a more mature osteogenic gene expression profile, indicated by a strong upregulation of the intermediate and late osteogenic markers ALP and OCN, respectively. The associated cellular microenvironment was also enriched in bone morphogenetic protein 2 (BMP-2). Interestingly, the resulting decellularized matrices exhibited the strongest osteo-inductive effects on re-seeded MSCs, promoted cell proliferation, osteogenic marker expression and ECM calcification. Taken together, these findings suggest that DxS-mediated enhancement of osteogenic differentiation by MSCs is mediated by the amplified ECM, which is enriched in osteo-inductive factors. We have thus established a simple and reproducible approach to generate ECM-rich bone-like tissue in vitro with sequestration of osteo-inductive factors. STATEMENT OF SIGNIFICANCE: As extracellular matrix (ECM) assembly is significantly retarded in vitro, the imbalance in ECM-to-cell ratio hampers current in vitro bone tissue engineering approaches in their ability to faithfully resemble their in vivo counterpart. We addressed this limitation by leveraging a poly-electrolyte mediated co-assembly and amplified deposition of ECM during osteogenic differentiation of human mesenchymal stem cells (MSCs). The resulting pericelluar space in culture was enriched in organic and inorganic bone ECM components, as well as osteo-inductive factors, which promoted the differentiation of MSCs towards a more mature osteoblastic phenotype. These findings thus demonstrated a simple and reproducible approach to generate ECM-rich bone-like tissue in vitro with a closer recapitulation of the in vivo tissue niche.

New Horizons for Hydroxyapatite Supported by DXA Assessment-A Preliminary Study. MATERIALS 2022; 15:ma15030942.

Abstract
Dual Energy X-ray Absorptiometry (DXA) is a tool that allows the assessment of bone density. It was first presented by Cameron and Sorenson in 1963 and was approved by the Food and Drug Administration. Misplacing the femoral neck box, placing a trochanteric line below the midland and improper placement of boundary lines are the most common errors made during a DXA diagnostic test made by auto analysis. Hydroxyapatite is the most important inorganic component of teeth and bone tissue. It is estimated to constitute up to 70% of human bone weight and up to 50% of its volume. Calcium phosphate comes in many forms; however, studies have shown that only tricalcium phosphate and hydroxyapatite have the characteristics that allow their use as bone-substituted materials. The purpose of this study is aimed at analyzing the results of hip densitometry and hydorxyapatite distribution in order to better assess the structure and mineral density of the femoral neck. However, a detailed analysis of the individual density curves shows some qualitative differences that may be important in assessing bone strength in the area under study. To draw more specific conclusions on the therapy applied for individual patients, we need to determine the correct orientation of the bone from the resulting density and document the trends in the density distribution change. The average results presented with the DXA method are insufficient.

Abstract
Since the introduction of biomaterials, infection has been a serious problem in clinical operations. Although several studies have introduced hybrid materials of calcium phosphate and Ag0 nanoparticles (NPs) that exhibit antibacterial activity, released Ag+ ions and Ag0 NPs are highly cytotoxic and the materials require complex fabrication techniques such as laser irradiation. In this study, we introduce a simple one-pot synthesis method based on crystal-engineering techniques to prepare Ag+-substituted octacalcium phosphate (OCP-Ag) powder that simultaneously exhibits antibacterial activity, little change in color, and low cytotoxicity, thereby overcoming the shortcomings of calcium phosphate as a biomaterial. We used AgNO3-containing (NH4)2HPO4 aqueous solutions as reaction solutions in which Ag+ forms soluble complex [Ag(NH3)2]+ ions that are stable at Ag+ concentrations less than ∼30 mmol/L. Hydrolysis of soluble calcium phosphate in this solution led to pure OCP-Ag when the Ag+ concentration was less than ∼30 mmol/L. Crystallographic analysis showed that Ag+ substituted at the P5 PO4-conjugated sites and was uniformly distributed. When the concentration of Ag+ in the reaction solution was varied, the Ag+ content of the OCP-Ag could be controlled. The obtained OCP-Ag exhibited little color change or Ag+ release when immersed in various media; however, it exhibited contact antibacterial ability toward resident oral bacteria. The prepared OCP-Ag showed no substantial cytotoxicity toward undifferentiated and differentiated MC3T3-E1 cells in assays. Notably, when the Ag+ content in OCP-Ag was optimized (Ag: ∼1 at %), it simultaneously exhibited contact antibacterial ability, little color change, and low cytotoxicity.

Abstract
Due to their simple crystal structures, one-dimensional hydroxyapatite (HA) nanostructures are easily to be applied to understand the fundamental concepts about the influences of HA dimensionality on physical, chemical, and biological properties. So, in this work, three typical HA one-dimensional nanostructures, HA nanotubes, HA nanowires, and HA nanospheres, were prepared, whose theoretical structures were built also. in vitro cytocompatibility test proved that, contrasting with TCPS, HA one-dimensional nanostructures had certain degree of cytotoxicity because HA nanostructures increase the generation of intracellular reactive oxygen species (ROS) and intracellular calcium. Theoretical simulation indicated that HA nanosphere has higher intracellular ROS generation and lower ROS storage amount than HA nanowire and HA nanotube, which were the possible reasons for its stronger cytotoxicity. Among these typical one-dimensional nanostructures, owing to higher drug storage amount and sustained delivery ability, HA nanotube was more potential application in orthopedics. The tubular structure of HA nanotubes could be used as reservoirs for small molecule drugs or growth factors. The cytocompatibility of HA nanostructures can be improved obviously when they were produced into two-dimensional structures. The prepared multilayer structure can simulate lamellar structures of Harvard system and enhance the cytocompatibility of Ti substrate. Therefore, the method used in this work is a prospective method to improve the inherently bio-inert of Ti when used in hard tissue repairing.

Abstract
The nanoparticles produced by magnetotactic bacteria, called magnetosomes, are made of a magnetite core with high levels of crystallinity surrounded by a lipid bilayer. This organized structure has been developed during the course of evolution of these organisms to adapt to their specific habitat and is assumed to resist degradation and to be able to withstand the demanding biological environment. Herein, we investigated magnetosomes' structural fate upon internalization in human stem cells using magnetic and photothermal measurements, electron microscopy, and X-ray absorption spectroscopy. All measurements first converge to the demonstration that intracellular magnetosomes can experience an important biodegradation, with up to 70% of their initial content degraded, which is associated with the progressive storage of the released iron in the ferritin protein. It correlates with an extensive magnetite to ferrihydrite phase transition. The ionic species delivered by this degradation could then be used by the cells to biosynthesize magnetic nanoparticles anew. In this case, cell magnetism first decreased with magnetosomes being dissolved, but then cells remagnetized entirely, evidencing the neo-synthesis of biogenic magnetic nanoparticles. Bacteria-made biogenic magnetosomes can thus be totally remodeled by human stem cells, into human cells-made magnetic nanoparticles.

Abstract
The objective of this work was to characterize the properties of a synthetic biomaterial composite with nanoparticles size (Blue Bone). This biomaterial is a composite recommended for dental and orthopedic grafting surgery, for guided bone regeneration, including maxillary sinus lift, fresh alveolus filling, and treatment of furcation lesions. The nano biomaterials surface area is from 30% to 50% higher than those with micro dimensions. Another advantage is that the alloplastic biomaterial has homogeneous properties due to the complete manufacturing control. The analyzed biomaterial composite was characterized by XRD, cytochemistry, scanning electron microscopy, porosimetry and in vivo experiments (animals). The results showed that the analyzed biomaterial composite has 78.76% hydroxyapatite [Ca5(PO4)3(OH)] with monoclinic structure, 21.03% β-tricalcium phosphate [β -Ca3(PO4)2] with trigonal structure and 0.19% of CaO with cubic structure, nanoparticles with homogeneous shapes, and nanoporosity. The in vivo experiments showed that the composite has null cytotoxicity, and the site of insertion biomaterials has a high level of vascularization and bone formation. The conclusion is that the synthetic biomaterial with Blue Bone designation presents characteristics suitable for use in grafting surgery applications.

Abstract
Osteosarcoma is the most common bone cancer with limited therapeutic options. It can be treated by selenium-doped hydroxyapatite owing to its known antitumor potential. However, a high concentration of Se is toxic toward normal and stem cells whereas its low concentration cannot effectively remove cancer cells. Therefore, the current study was aimed to improve the anticancer activity of Se-HAp nanoparticles through catechins (CC) modification owing to their high cancer therapeutic value. The sequentially developed catechins modified Se-HAp nanocomposites (CC/Se-HAp) were characterized for various physico-chemical properties and antitumor activity. Structural analysis showed the synthesis of small rod-like single phase HAp nanoparticles (60 ± 15 nm), which effectively interacted with Se and catechins and formed agglomerated structures. TEM analysis showed the internalization and degradation of CC/Se-HAp nanomaterials within MNNG/HOS cells through a non-specific endocytosis process. Cell toxicity analysis showed that catechins modification improved the antitumor activity of Se-HAp nanocomposites by inducing apoptosis of human osteosarcoma MNNG/HOS cell lines, through generation of reactive oxygen species (ROS) which in turn activated the caspase-3 pathway, without significantly affecting the growth of human normal bone marrow stem cells (hBMSCs). qPCR and western blot analyses revealed that casp3, p53, and bax genes were significantly upregulated while cox-2 and PTK-2 were slightly downregulated as compared to control in CC/Se-HAp-treated MNNG/HOS cell lines. The current study of combining natural biomaterial (i.e., catechins) with Se and HAp, can prove to be an effective therapeutic approach for bone cancer therapy.

Abstract
Nanostructured carbonated hydroxyapatite (nCHA) is a promising biomaterial for bone tissue engineering due to its chemical properties, similar to those of the bone mineral phase and its enhanced in vivo bioresorption. However, the biological effects of nCHA nanoparticles on cells and tissues are not sufficiently known. This study assessed the impact of exposing pre-osteoblasts to suspensions with high doses of nCHA nanoparticles with high or low crystallinity. MC3T3-E1 pre-osteoblasts were cultured for 1 or 7 days in a culture medium previously exposed to CHA nanoparticles for 1 day. Control groups were produced by centrifugation for removal of bigger nCHA aggregates before exposure. Interaction of nanoparticles with the culture medium drastically changed medium composition, promoting Ca, P, and protein adsorption. Transmission Electron microscopy revealed that exposed cells were able to internalize both materials, which seemed concentrated inside endosomes. No cytotoxicity was observed for both materials, regardless of centrifugation, and the exposure did not induce alterations in the release of pro-and anti-inflammatory cytokines. Morphological analysis revealed strong interactions of nCHA aggregates with cell surfaces, however without marked alterations in morphological features and cytoskeleton ultrastructure. The overall in vitro biocompatibility of nCHA materials, regardless of physicochemical characteristics such as crystallinity, encourages further studies on their clinical applications.
