| 4 | Bone without borders-Monetite-based calcium phosphate guides bone formation beyond the skeletal envelope显示文摘Calcium phosphates(CaP)represent an important class of osteoconductive and osteoinductive biomaterials.As proof-of-concept,we show how a multi-component CaP formulation(monetite,beta-tricalcium phosphate,and calcium pyrophosphate)guides osteogenesis beyond the physiological envelope.In a sheep model,hollow dome-shaped constructs were placed directly over the occipital bone.At 12 months,large amounts of bone(~75%)occupy the hollow space with strong evidence of ongoing remodelling.Features of both compact bone(osteonal/osteon-like arrangements)and spongy bone(trabeculae separated by marrow cavities)reveal insights into function/need-driven microstructural adaptation.Pores within the CaP also contain both woven bone and vascularised lamellar bone.Osteoclasts actively contribute to CaP degradation/removal.Of the constituent phases,only calcium pyrophosphate persists within osseous(cutting cones)and non-osseous(macrophages)sites.From a translational perspective,this multi-component CaP opens up exciting new avenues for osteotomy-free and minimally-invasive repair of large bone defects and augmentation of the dental alveolar ridge. | Furqan A.Shah Martina Jolic Chiara Micheletti Omar Omar Birgitta Norlindh Lena Emanuelsson Håkan Engqvist Thomas Engstrand Anders Palmquist Peter Thomsen | 2023 | Bioactive Materials2023，，1： | 0 |
| 5 | Magnesium implant degradation provides immunomodulatory and proangiogenic effects and attenuates peri-implant fibrosis in soft tissues显示文摘Implants made of magnesium(Mg)are increasingly employed in patients to achieve osteosynthesis while degrading in situ.Since Mg implants and Mg^(2+)have been suggested to possess anti-inflammatory properties,the clinically observed soft tissue inflammation around Mg implants is enigmatic.Here,using a rat soft tissue model and a 1-28 d observation period,we determined the temporo-spatial cell distribution and behavior in relation to sequential changes of pure Mg implant surface properties and Mg^(2+)release.Compared to nondegradable titanium(Ti)implants,Mg degradation exacerbated initial inflammation.Release of Mg degradation products at the tissue-implant interface,culminating at 3 d,actively initiated chemotaxis and upregulated mRNA and protein immunomodulatory markers,particularly inducible nitric oxide synthase and toll-like receptor-4 up to 6 d,yet without a cytotoxic effect.Increased vascularization was demonstrated morphologically,preceded by high expression of vascular endothelial growth factor.The transition to appropriate tissue repair coincided with implant surface enrichment of Ca and P and reduced peri-implant Mg^(2+)concentration.Mg implants revealed a thinner fibrous encapsulation compared with Ti.The detailed understanding of the relationship between Mg material properties and the spatial and time-resolved cellular processes provides a basis for the interpretation of clinical observations and future tailoring of Mg implants. | Heithem Ben Amara Diana C.Martinez Furqan A.Shah Anna Johansson Loo Lena Emanuelsson Birgitta Norlindh Regine Willumeit-Römer Tomasz Plocinski Wojciech Swieszkowski Anders Palmquist Omar Omar Peter Thomsen | 2023 | Bioactive Materials2023，，8： | 0 |
