Akiyama M. Role of FBXW2 in explant cultures of bovine periosteum-derived cells. BMC Res Notes 2021; 14:410.

Abstract
OBJECTIVE Bone regeneration is a potential technique for treating osteoporosis. A previous study reported that F-box and WD-40 domain-containing protein 2 (FBXW2) localized with osteocalcin in bovine periosteum after 5 weeks of explant culture. However, the osteoblastic functions of FBXW2 remain unclear. In this study, double-fluorescent immunostaining was used to investigate the potential role of FBXW2 and its relationship with osteocalcin. RESULTS At day 0, FBXW2 was expressed in the cambium layer between the bone and periosteum, while osteocalcin was expressed in bone. After explant culture, changes in the periosteum were observed from weeks 1 to 7. At week 1, partial FBXW2 expression was seen with a small amount of osteocalcin. At week 2, a layer of FBXW2 was observed. From weeks 3 to 7, tube-like structures of FBXW and osteocalcin were observed, and periosteum-derived cells were released from the periosteum in areas where no FBXW2 was observed. Bovine periosteum-derived cells can form a three-dimensional cell pellet, because multilayered cell sheets are formed inside of the periosteum in vitro. It is shown that in results FBXW2 is produced in periosteal explants near sites where initial osteogenic activity is observed, suggesting that it may be involved in periosteal osteogenesis.

Abstract
Central ischemic necrosis is one of the biggest obstacles in the clinical application of traditional tissue-engineered bone (TEB) in critical-sized bone defect regeneration. Because of its ability to promote vascular invasion, endochondral ossification-based TEB has been applied for bone defect regeneration. However, inadequate chondrocyte hypertrophy can hinder vascular invasion and matrix mineralization during endochondral ossification. In light of recent studies suggesting that ceria nanoparticles (CNPs) improve the blood vessel distribution within TEB, we modified TEB scaffold surfaces with CNPs and investigated the effect and mechanism of CNPs on endochondral ossification-based bone regeneration. The CNPs used in this study were synthesized by the microemulsion method and modified with alendronate-anchored polyethylene glycol 600. We showed that CNPs accelerated new bone formation and enhanced endochondral ossification-based bone regeneration in both a subcutaneous ectopic osteogenesis model and a mouse model of critical-sized bone defects. Mechanistically, CNPs significantly promoted endochondral ossification-based bone regeneration by ensuring sufficient hypertrophic differentiation via the activation of the RNA helicase, DEAH (Asp-Glu-Ala-His) box helicase 15, and its downstream target, p38 MAPK. These results suggested that CNPs could be applied as a biomaterial to improve the efficacy of endochondral ossification-based bone regeneration in critical-sized bone defects.-Li, J., Kang, F., Gong, X., Bai, Y., Dai, J., Zhao, C., Dou, C., Cao, Z., Liang, M., Dong, R., Jiang, H., Yang, X., Dong, S.

[PMID: 30450135 PMCID: PMC6198513 DOI: 10.2174/1874120701812010075] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2018] [Revised: 10/01/2018] [Accepted: 10/02/2018] [Indexed: 01/11/2023] Open
Abstract
Background: Cultured bovine-periosteum-derived cells can form three-dimensional structures on tissue culture dishes without artificial scaffolding material, can induce bone regeneration in vivo. The utility of cultured bovine-periosteum-derived cells for bone tissue regeneration after their transplantation into nude mice has been reported, the precise F-box molecular mechanism was unclear. Objective: The aim of this study was to investigate the specific F-box proteins required for bone regeneration by cultured bovine-periosteum-derived cells in vitro. Methods: In the present study, periosteum tissue and cultured periosteum-derived cells were cultured for 5 weeks in vitro and then embedded in collagen gel with a green tissue-marking dye. Electrophoresis and immunohistochemistry were used to identify the specific F-box proteins required for tissue bone regeneration. Results: The bovine-periosteum-derived cells were observed to form bone shortly after the expression of F-box proteins. After the initial phase of bone formation, the expression of the F-box proteins ceased. FBXW2 was shown to be expressed in the periosteum, but not in cultured periosteum-derived cells. Furthermore, FBXL14 disappeared during bone formation. Conclusions: Bone regeneration requires progenitor cells, such as bovine-periosteum-derived cells and the activation of the F-box Proteins FBXW2 and FBXL14, over time the expression of these proteins ceases. Further scientific and clinical trials are needed to investigate how the F-box Proteins can be used therapeutically to treat osteoporosis and osteonecrosis.

Abstract
Osteocalcin (OC) is a well-known protein related to bone, however, the role of F-box and WD-40 domain-containing protein 2 (FBXW2) in bone remains unclear. In 2016, the presence of FBXW2 in bovine periosteum was reported. In this study, double immunostaining was used to investigate the relationship between OC and FBXW2. FBXW2 showed tubular structures, and OC showed a similar localization pattern as FBXW2. Double immunostaining findings suggested that FBXW2 tubes were coated with OC. To the author's knowledge, this is the first study to reveal the interaction between OC and FBXW2.

Abstract
Spinal fusion and bone defect after injuries, removal of bone tumors, and infections need to be repaired by implantation. In an aging society, recovery from these procedures is often difficult. In this study, we found that injection of SPG-178 leads to expression of several bone marker genes and mineralization in vitro, and revealed a significantly higher degree of newly formed bone matrix with use of SPG-178 in vivo. MC3T3-E1 cells were used to evaluate osteoblast differentiation promoted by SPG-178. To analyze gene expression, total RNA was isolated from MC3T3-E1 cells cultured for 7 and 14 days with control medium or SPG-178 medium. Among the several bone marker genes examined, SPG-178 significantly increased the mRNA levels for ALP, BMP-2 and Osteocalcin, OPN, BSP and for the Osterix. Ten-week-old female Wistar rats were used for all transplantation procedures. A PEEK cage was implanted into a bony defect (5 mm) within the left femoral mid-shaft, and stability was maintained by an external fixator. The PEEK cages were filled with either a SPG-178 hydrogel plus allogeneic bone chips (n = 4) or only allogeneic bone chips (n = 4). The rats were then kept for 56 days. Newly formed bone matrix was revealed inside the PEEK cage and there was an increased bone volume per total volume with the cage filled with SPG-178, compared to the control group. SPG-178 has potential in clinical applications because it has several benefits. These include its favorable bone conduction properties its ability to act as a support for various different cells and growth factors, its lack of infection risk compared with materials of animal origin such as ECM, and the ease with which it can be used to fill defects with complex shapes and combined with a wide range of other materials.

Abstract
For the first time, electrospun polycaprolactone (PCL) 3D nanofibrous scaffold has been developed by an innovative and convenient approach (i.e., thermally induced nanofiber self-agglomeration followed by freeze drying), and the scaffold possesses interconnected and hierarchically structured pores including macropores with sizes up to ≈300 μm. The novel PCL 3D scaffold is soft and elastic with very high porosity of ≈96.4%, thus it is morphologically/structurally similar to natural extracellular matrix and well suited for cell functions and tissue formation. The in vitro studies reveal that the scaffold can lead to high cell viability; more importantly, it is able to promote more potent BMP2-induced chondrogenic than osteogenic differentiation of mouse bone marrow mesenchymal stem cells. Consistent to the in vitro findings, the in vivo results indicate that the electrospun PCL 3D scaffold acts as a favorable synthetic extracellular matrix for functional bone regeneration through the physiological endochondral ossification process.

Abstract
Inspection of patient-derived cells used in transplantation is non-invasive. Therefore, proteomics analysis using supernatants of cells cultured before transplantation is informative. In order to investigate the cell niche of bovine periosteal cells, supernatants of these cultured cells were subjected to 2-D electrophoresis followed by mass spectrometry, which identified type 1 collagen and the C-terminus of type 3 collagen. Only the C-terminal peptide from type 3 collagen was found in supernatants. It is known that type 3 collagen may be expressed intra- or extra-cellularly. Paraffin sections of the cultured cells were next examined by immunohistochemistry, which revealed that type 3 collagen regions besides the C-terminal peptide were present around the bovine periosteal cells but were not found in supernatants. Full-length type 3 collagen was closely associated with the cells, and only the C-terminal peptide was detectable in culture supernatants. Mass spectrometry analysis of partial peptide data combined with immunohistochemistry also indicated that uveal autoantigen with coiled coil domains and ankyrin repeats (UACA), exosome complex component RRP45 (EXOSC9), and thioredoxin-related transmembrane protein 2 (TMX2) were expressed in bovine periosteal cells. Results of this study indicate that analysis of culture supernatants before cell transplantation can provide useful biomarkers indicating the niche of cells used for transplantation.

Abstract
Mechanical properties of the extracellular matrix (ECM) play an essential role in cell fate determination. To study the role of mechanical properties of ECM in stem cell-mediated bone regeneration, we used a 3D in vivo ossicle model that recapitulates endochondral bone formation. Three-dimensional gelatin scaffolds with distinct stiffness were developed using 1-Ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride (EDC) mediated zero-length crosslinking. The mechanical strength of the scaffolds was significantly increased by EDC treatment, while the microstructure of the scaffold was preserved. Cell behavior on the scaffolds with different mechanical properties was evaluated in vitro and in vivo. EDC-treated scaffolds promoted early chondrogenic differentiation, while it promoted both chondrogenic and osteogenic differentiation at later time points. Both micro-computed tomography and histologic data demonstrated that EDC-treatment significantly increased trabecular bone formation by transplanted cells transduced with AdBMP. Moreover, significantly increased chondrogenesis was observed in the EDC-treated scaffolds. Based on both in vitro and in vivo data, we conclude that the high mechanical strength of 3D scaffolds promoted stem cell mediated bone regeneration by promoting endochondral ossification. These data suggest a new method for harnessing stem cells for bone regeneration in vivo by tailoring the mechanical properties of 3D scaffolds.

Filtration of dermal fibroblast-conditioned culture media is required for the reliable quantitation of cleaved carboxy-terminal peptide of collagen type I (CICP) by ELISA. Arch Dermatol Res 2013; 305:741-5.

Abstract
Cleavage of the collagen type I carboxy-terminal peptide (CICP) from the procollagen molecule is an essential step in collagen biosynthesis. The commercial CICP ELISA (Quidel Corporation, USA), developed for quantifying CICP in serum in clinical monitoring, is often also applied to cellular studies as a measure of collagen synthesis. However, unlike in serum samples, which contain only cleaved CICP, cell-conditioned culture media also contains "uncleaved CICP", namely procollagen, and there is no specific guidance on how to interpret the ELISA data obtained with such samples. Here we attempted to reliably quantify cleaved CICP in human dermal fibroblast-conditioned cell culture media using the CICP ELISA. CICP concentration was determined in the parent and filtered samples of culture media of dermal fibroblasts (CCD-25SK). Gel-separated samples were also subjected to protein staining or analyzed by Western blot using the anti-CICP antibodies supplied in the ELISA kit. The derived concentrations of CICP in the filtered aliquots and the parent unfiltered samples increased over time. The increase in CICP in the unfiltered samples was not proportional to the increase seen in the filtered aliquot. CICP ELISA antibodies recognized both the cleaved CICP trimer and procollagen molecule. The data presented show that (a) the commercial CICP ELISA recognizes both procollagen and cleaved CICP in cell-conditioned culture media and thus attention should be paid in interpreting data from cell culture studies using this ELISA and (b) the filtration method described herein can be used to exclusively and reliably monitor cleaved CICP.

Abstract
Transplantation of bone marrow (BM) CD34+ cells, an endothelial/hematopoietic progenitor-enriched cell population, has shown therapeutic efficiency in the treatment of ischemic diseases enhancing neovascularization. However, the number of CD34+ cells obtained from bone marrow is not sufficient for routine clinical application. To overcome this issue, we developed a more efficient and clinically applicable CD34+ cell expansion method. Seven-day ex vivo expansion culture of BM CD34+ cells with a cocktail of five growth factors containing VEGF, SCF, IL-6, Flt-3 ligand, and TPO resulted in reproducible more than 20-fold increase in cell number. The favorable effect of the local transplantation of culture expanded (cEx)-BM CD34+ cells on rat unhealing fractures was equivalent or higher than that of nonexpanded (fresh) BM CD34+ cells exhibiting sufficient therapeutic outcome with frequent vasculogenic/osteogenic differentiation of transplanted cEx-BM CD34+ cells and fresh BM CD34+ cells as well as intrinsic enhancement of angiogenesis/osteogenesis at the treated fracture sites. Specifically, cEx-BM CD34+ cell treatment demonstrated the best blood flow recovery at fracture sites compared with the nonexpanded BM CD34+ cells. In vitro, cEx-BM CD34+ cells showed higher colony/tube-forming capacity than nonexpanded BM CD34+ cells. Both cells demonstrated differentiation potential into osteoblasts. Since fresh BM CD34+ cells can be easily collected from fracture sites at the time of primary operation and stored for future use, autologous cEx-BM CD34+ cell transplantation would be not only a simple but also a promising therapeutic strategy for unhealing fractures in the field of orthopedic trauma surgery.

Abstract
We previously reported the therapeutic potential of human peripheral blood (hPB) CD34+ cells for bone fracture healing via vasculogenesis/angiogenesis and osteogenesis. Transplantation of not only hPB CD34+ cells but also hPB total mononuclear cells (MNCs) has shown their therapeutic efficiency for enhancing ischemic neovascularization. Compared with transplantation of purified hPB CD34+ cells, transplantation of hPB MNCs is more attractive due to its simple method of cell isolation and inexpensive cost performance in the clinical setting. Thus, in this report, we attempted to test a hypothesis that granulocyte colony-stimulating factor-mobilized (GM) hPB MNC transplantation could also contribute to fracture healing via vasculogenesis/angiogenesis and osteogenesis. Nude rats with unhealing fractures received local administration of the following materials with atelocollagen: 1 × 107 GM hPB MNCs (Hi group), 1 × 106 GM hPB MNCs (Lo group), or PBS (PBS group). Immunohistochemistry and real-time reverse transcriptase-polymerase chain reaction (RT-PCR) demonstrated human cell-derived vasculogenesis and osteogenesis in the Hi and Lo groups, but not in the PBS group at week 1. Intrinsic angiogenesis and osteogenesis assessed by rat capillary, osteoblast density, and real-time RT-PCR analysis was significantly enhanced in the Hi group compared to the other groups. Blood flow assessment by laser doppler perfusion imaging showed a significantly higher blood flow ratio at week 1 in the Hi group compared with the other groups. Morphological fracture healing was radiographically and histologically confirmed in about 30% of animals in the Hi group at week 8, whereas all animals in the other groups resulted in nonunion. Local transplantation of GM hPB MNCs contributes to fracture healing via vasculogenesis/angiogenesis and osteogenesis.

Abstract
The aim of the present study was to investigate the osteogenic capability of rat calvarial periosteal cells in hypoxic conditions in vitro. Periosteum was obtained from the calvarial bone of Sprague-Dawley rats. Following primary tissue culture, subcultured cells were used in hypoxic or normal conditions. On days 1, 2, 3 and 4 following the cell culture, cell proliferation and mRNA and protein expression levels were evaluated. No significant difference in the cell proliferation rate was found between the normal and hypoxic condition groups. The hypoxic condition group exhibited a stronger expression of hypoxia-inducible factor (HIF)1α, vascular endothelial growth factor (VEGF), Runx2, alkaline phosphatase (ALP), bone sialoprotein (BSP), osteocalcin (OCN) and periostin at the mRNA level compared to that of the normal condition group. The hypoxic condition group also exhibited a stronger expression of HIF1α, VEGF, bone morphogenetic protein (BMP)2, Runx2, ALP and BSP at the protein level compared to that of the normal condition group. In conclusion, periosteal cells cultured in hypoxic conditions demonstrated activated osteogenic capability in vitro.

In-vivo generation of bone via endochondral ossification by in-vitro chondrogenic priming of adult human and rat mesenchymal stem cells. BMC Musculoskelet Disord 2011; 12:31.

Abstract
BACKGROUND Bone grafts are required to repair large bone defects after tumour resection or large trauma. The availability of patients' own bone tissue that can be used for these procedures is limited. Thus far bone tissue engineering has not lead to an implant which could be used as alternative in bone replacement surgery. This is mainly due to problems of vascularisation of the implanted tissues leading to core necrosis and implant failure. Recently it was discovered that embryonic stem cells can form bone via the endochondral pathway, thereby turning in-vitro created cartilage into bone in-vivo. In this study we investigated the potential of human adult mesenchymal stem cells to form bone via the endochondral pathway. METHODS MSCs were cultured for 28 days in chondrogenic, osteogenic or control medium prior to implantation. To further optimise this process we induced mineralisation in the chondrogenic constructs before implantation by changing to osteogenic medium during the last 7 days of culture. RESULTS After 8 weeks of subcutaneous implantation in mice, bone and bone marrow formation was observed in 8 of 9 constructs cultured in chondrogenic medium. No bone was observed in any samples cultured in osteogenic medium. Switch to osteogenic medium for 7 days prevented formation of bone in-vivo. Addition of β-glycerophosphate to chondrogenic medium during the last 7 days in culture induced mineralisation of the matrix and still enabled formation of bone and marrow in both human and rat MSC cultures. To determine whether bone was formed by the host or by the implanted tissue we used an immunocompetent transgenic rat model. Thereby we found that osteoblasts in the bone were almost entirely of host origin but the osteocytes are of both host and donor origin. CONCLUSIONS The preliminary data presented in this manuscript demonstrates that chondrogenic priming of MSCs leads to bone formation in vivo using both human and rat cells. Furthermore, addition of β-glycerophosphate to the chondrogenic medium did not hamper this process. Using transgenic animals we also demonstrated that both host and donor cells played a role in bone formation. In conclusion these data indicate that in-vitro chondrogenic differentiation of human MSCs could lead to an alternative and superior approach for bone tissue engineering.

Abstract
Although implantation of crude bone marrow cells has been applied in a small number of patients for fracture healing, transplantation of peripheral blood CD34(+) cells, the hematopoietic/endothelial progenitor cell-enriched population, in patients with fracture has never been reported. Here, we report the first case of tibial nonunion receiving autologous, granulocyte colony stimulating factor mobilized CD34(+) cells accompanied with autologous bone grafting. No serious adverse event occurred, and the novel therapy performed 9 months after the primary operation resulted in bone union 3 months later without any symptoms including pain and gait disturbance.

Abstract
Self-assembling peptide scaffold (SAPS) is well known to have very good bone conduction properties. However, the intensity of SAPS is too weak to actually use it for a clinical bone regeneration. Therefore, we have produced a hybrid scaffold system that involves fabricating a cage from polyetheretherketone (PEEK) that has high intensity, filling the interior of this cage with SAPS, and then transplanted this hybrid scaffold to bone defects in rat femurs. After 28 days, soft X-ray radiographs and histological assessment revealed that good new bone formation was clearly observed in the defects transplanted the PEEK cage with SAPS, but not in the PEEK cage only. The PEEK cage maintained a form and osteoconduction ability of internal SAPS, and SAPS promoted bone formation inside the PEEK; therefore, each was in charge of intensity and bone regeneration separately. The present study suggests that hybrid scaffolds made from PEEK cages and SAPS can be useful tools for the regeneration of load-bearing bones, based on the idea that it should be possible to develop ideal bone filler materials by combining the strength of artificial bone with the bone regeneration and bone conduction properties of SAPS.
