In this study, we developed a 3D-printed magnesium- and strontium-co-doped calcium silicate (MSCS) scaffold using direct ink writing to optimize its bioactivity and structural integrity. X-ray diffraction confirmed the successful incorporation of Sr and Mg, leading to phase modifications that influenced ion release and degradation. Wettability and mechanical testing showed that Sr improved the stability, while Mg accelerated degradation, with M5S5 co-doping exhibiting a balanced degradation profile. In vitro, Wharton's jelly mesenchymal stromal cells cultured on M5S5 scaffolds displayed enhanced proliferation, cytoskeletal organization, and osteogenic differentiation, as evidenced by increased alkaline phosphatase activity and bone matrix protein expression. Angiogenesis assays using human umbilical vein endothelial cells revealed that Sr and Mg co-doping synergistically enhanced vascular endothelial growth factor and angiopoietin-1 secretion, thereby promoting endothelial tube formation. In vivo micro-computed tomography and histological analysis of a rabbit femoral defect model confirmed that M5S5 facilitated extensive new bone formation, exhibiting superior trabecular architecture and mineralization.

In the article, the word 'fossil' refers to all forms of mined carbon and minerals from the Earth, including water from aquafers, which cannot be replenished at the rate that will maintain their capacity to provide for the future. The natural world through its many circular systems uses energy and renewable resources to perform functions that produce zero waste. One organism's waste becomes another organism's food, material, and energy, forming a circular loop (take-make-use-decay-reuse). Over the past 4 years, deliberate engagements with leaders of multiple disciplines and stakeholders resulted in conclusions that the problems of the complex biologically active systems (biosystems) that are intertwined with natural systems and socio-economic systems can only be addressed by having a robust culture of convergent science and engineering and systems-thinking for transitioning from linear fossil-based to circular bioeconomy systems. We present the need and propose forming a multidisciplinary professional society alliance to promote and support networks of multidisciplinary teams to address problems of complex, intertwined bio-natural-socio-economic systems of systems. This article proposes that the Institute of Biological Engineering (IBE), a society whose primary objective is to \"to apply biology-inspired engineering principles to design systems to improve the quality of the human condition\", and inculcates a culture of convergent science and engineering that has members representing expertise of multiple science and engineering discipline, is potentially an excellent candidate to play a pivotal role in designing innovative solutions for advancing sustainable circular bioeconomy systems.</p>","PeriodicalId":15053,"journal":{"name":"Journal of Biological Engineering","volume":"19 1","pages":"57"},"PeriodicalIF":5.7,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12180189/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144333199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
