AbstractAdult bone regeneration is orchestrated by the precise actions of osteoprogenitor cells (OPCs). However, the mechanisms by which OPC proliferation and differentiation are linked and thereby regulated are yet to be defined. Here, we present evidence that during intramembranous bone formation OPC proliferation is controlled by Notch signaling, while differentiation is initiated by activation of canonical Wnt signaling. The temporospatial separation of Notch and Wnt signal activation during the early stages of bone regeneration suggests crosstalk between the two pathways. In vitro and in vivo manipulation of the two essential pathways demonstrate that Wnt activation leads to initiation of osteogenic differentiation and at the same time inhibits Notch signaling, which results in termination of the proliferative phase. Here, we establish canonical Wnt signaling as a key regulator that facilitates the crosstalk between OPC proliferation and differentiation during intramembranous, primary bone healing.

Abstract Objective The purpose was to observe whether systemic administration with silibinin(SIL) have an positive effect on bone defect regeneration through HIF-1α/VEGF and Notch signaling pathway in an ovariectomized(OVX) rat model. Methods The MC3T3-E1 cells were co-cultured with lower SIL and higher SIL and induced to osteogenesis, and the cell viability, osteogenic activity were observed by Cell Count Kit-8(CCK-8), Alkaline phosphatase (ALP) staining, Alizarin Red(RES) staining and Western blotting(WB). After the drilling defect model was established, the OVX rats were treated with SIL for 12 weeks. Micro-CT, histology and Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis were used to observe the therapeutic effect and explore the possible mechanism. Results CCK-8, ALP and ARS staining results show that the cell mineralization and osteogenic activity of LSIL and HSIL group is significantly higher than the Con group. Protein expressions show that related regulatory proteins such as ALP, OPN, RUNX-2, OC, VEGFA, HIF-1α, Notch 1, JAG 1, HEY 1 and HES 1 of LSIL and HSIL group are significantly higher than Con group. Micro-CT and Histological analysis evaluation show that group SIL + OVX presented the stronger effect on bone regeneration, bone mineralization, higher expression of VEGFA and HIF-1α, when compared with OVX group. RT-qPCR analysis shows that SIL + OVX group showed increased Notch 1, HES1, HEY1 and JAG1 than the OVX group(p < 0.05). Conclusions Our current study demonstrated that systemic administration with SIL is a scheme for rapid repair of femoral condylar defects, and these effects may be achieved by activating HIF-1α/VEGF and Notch signaling pathway.

Bone possesses an intrinsic regenerative capacity, which can be compromised by aging, disease, trauma, and iatrogenesis (e.g. tumor resection, pharmacological). At present, autografts and allografts are the principal biological treatments available to replace large bone segments, but both entail several limitations that reduce wider use and consistent success. The use of decellularized extracellular matrices (ECM), often derived from xenogeneic sources, has been shown to favorably influence the immune response to injury and promote site-appropriate tissue regeneration. Decellularized bone ECM (dbECM), utilized in several forms — whole organ, particles, hydrogels — has shown promise in both in vitro and in vivo animal studies to promote osteogenic differentiation of stem/progenitor cells and enhance bone regeneration. However, dbECM has yet to be investigated in clinical studies, which are needed to determine the relative efficacy of this emerging biomaterial as compared with established treatments. This mini-review highlights the recent exploration of dbECM as a biomaterial for skeletal tissue engineering and considers modifications on its future use to more consistently promote bone regeneration.
