Understanding how the bone niche interacts with tumor cells and the mechanisms leading to drug resistance is a crucial step for enabling the identification of effective cancer therapies. Nevertheless, bone tumor research and the development of new effective anticancer drugs have been hampered for a long time due to the limitations of preclinical models. Traditional 2D cultures and animal models have failed to accurately replicate the human bone cancer microenvironment, driving researchers to develop 3D <em>in vitro</em> bone models using tissue-engineered bone constructs and advanced technologies like microfluidics and additive manufacturing. While a complete reproduction of the bone tumor microenvironment (TME), including all relevant cell types, stromal elements, and biophysical cues, remains elusive, targeted inclusion of key components has advanced the physiological relevance of these models. The following review evaluates the biomimetic approaches that have been used to recapitulate the bone TME through 3D <em>in vitro</em> models, with particular attention to recent studies aimed at more accurately mimicking the complexity of bone TME, highlighting future directions and the advancements required to overcome present limitations.</div></div>","PeriodicalId":48806,"journal":{"name":"Journal of Bone Oncology","volume":"53 ","pages":"Article 100698"},"PeriodicalIF":3.4,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
