Abstract
BACKGROUND The effect of functional orthopaedic treatment for mandibular deficiency relies on mandibular advancement (MA)-induced condylar new bone formation. However, this is not easy to achieve, especially in non-growing patients. Therefore, how to obtain reliable MA-induced condylar osteogenesis is a subject much worthy of study. OBJECTIVE To investigate whether deferoxamine mesylate (DFM) enhances MA-induced condylar osteogenesis in middle-aged mice. METHODS Forty 30-week-old male C57BL/6J mice were randomly divided into 4 groups: the control (Ctrl), DFM, MA + Ctrl and MA + DFM groups. After a 4-week experimental period, femurs, tibias and condyles were collected for morphological, micro-computed tomography and histological evaluation. RESULTS For long bones, DFM reversed osteoporosis in middle-aged mice by promoting H-type angiogenesis. For mandibular condyles, MA promoted condylar osteogenesis in middle-aged mice, thereby allowing the mandible to achieve a stable protruding position. In addition, DFM enhanced the volume and quality of MA-induced condylar new bone formation. Furthermore, histological analysis revealed that DFM enhanced MA-induced condylar subchondral ossification. Mechanistically, it was confirmed that DFM increased the number of H-type vessels and their coupled Osterix+ osteoprogenitors by upregulating the hypoxia-inducible factor (HIF)-1α signalling pathway, thereby enhancing MA-induced condylar osteogenesis. CONCLUSION Applying DFM to enhance MA-induced condylar osteogenesis through H-type angiogenesis is expected to be an effective strategy to achieve favourable functional orthopaedic treatment effectiveness in non-growing patients.

Abstract
Type H vessel is a specific vessel subtype that is strongly positive for CD31 and endomucin (CD31hiEmcnhi). It has already been identified that it can tightly regulate the coupling of angiogenesis and osteogenesis in the long bone of mice and human beings. The long bone is formed through endochondral ossification, which is the same type of process happening in mandibular condyle. Although the ossification of long bone and mandibular condyle has the same developmental process, the existence of type H vessels in the mouse condyle remains unclear. To address this, we identified that abundant type H vessels existed in the subchondral bone of the mouse condylar head and endosteum of the mouse condylar neck. Meanwhile, immunofluorescence imaging of the condyles in different ages of male C57BL/6J mice demonstrated that type H vessels decreased while aging. Furthermore, we validated a positive correlation between type H vessels and Osterix+ osteoprogenitors in the condyle induced by mandibular advancement. Mechanistically, we confirmed that deferoxamine mesylate, which promoted the proliferation of type H endothelial cells by activating hypoxia-inducible factor 1α (HIF-1α) signaling pathways, largely prevented the osteopenia in the condyle induced by botulinum toxin type A. Collectively, these results demonstrate that in the mouse condyle, type H vessels in areas of high function positively correlate with bone formation. In addition, we show a novel influence of HIF-1α signaling on osteogenesis via an increase in type H vessels. In conclusion, promoting angiogenesis of type H vessels is a promising strategy for the therapeutic improvement of osteogenesis in mandibular condyle.

Int J Mol Med 2017; 41:729-738. [PMID: 29207140 PMCID: PMC5752241 DOI: 10.3892/ijmm.2017.3258] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2017] [Accepted: 11/02/2017] [Indexed: 11/13/2022] Open
Abstract
Platelet-rich plasma (PRP) is used in the clinic as an autologous blood product to stimulate bone regeneration and chondrogenesis. Numerous studies have demonstrated that PRP affects bone remodeling by accelerating osteoblast formation. With the research perspective focusing on osteoclasts, the present study established a mouse model of mandibular advancement to examine the effect of PRP on osteoclast differentiation induced by modification of the dynamics of the temporomandibular joint (TMJ). The lower incisors of the mice were trimmed by 1 mm and the resultant change in mandibular position during the process of eating induced condylar adaptation to this change. PRP significantly increased the bone mass and decreased osteoclastic activity, in vitro as well as in vivo. Mechanistically, the reduced expression of receptor activator of nuclear factor-κB ligand (RANKL)-induced differentiation marker genes, including nuclear factor of activated T-cells, cytoplasmic 1, c-fos and tartrate-resistant acid phosphatase, and that of the resorptive activity marker genes such as cathepsin k, carbonic anhydrase 2 and matrix metalloproteinase 9, indicated that PRP suppresses RANKL-induced osteoclast differentiation. A microarray analysis revealed that several genes associated with the Wnt pathway were differentially expressed, which indicated the involvement of this pathway in osteoclast differentiation. Furthermore, the activation of the Wnt pathway was verified by reverse transcription-quantitative polymerase chain reaction and immunoblot analysis of Dickkopf-related protein 1 and β-catenin. The results of the present study indicated that PRP inhibits osteoclast differentiation through activation of the Wnt pathway.
