However, small molecules have been suggested as alternatives to recombinant protein-based treatments because of their unique advantages. To date, therapeutic methods for orthopaedic applications still heavily rely on therapeutic protein-based growth factors. This trend is likely to be reversed since innovative drug discovery strategies, such as broad-spectrum database analysis and high throughput functional screens, have led to the discovery of many novel small molecule compounds and the development of novel applications of existing approved small molecule compounds. It should be noted that some of these small molecules with osteoinductive potential have been approved for human use due to their efficacy in treating other health ailments. Thus, these approved small molecule compounds are highly translatable to orthopaedic applications. In this article, we review the literature, paying attention to the prospects of existing approved small molecule therapeutics with bone regenerative capacity. Future directions of bone repair and regeneration using these approved small molecule drugs will be discussed as well.","PeriodicalId":269533,"journal":{"name":"Advances in Regenerative Biology","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131935718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reinhart-King","doi":"10.3402/arb.v1.25247","DOIUrl":"https://doi.org/10.3402/arb.v1.25247","url":null,"abstract":"Angiogenesis, the process where new blood vessels form from existing vasculature, is essential for the successful integration of most tissue-engineered constructs and is dysregulated in many diseases, including cancer. To be functional, the newly formed vasculature must have similar structure and integrity as existing blood vessels, both of which are dependent upon mechanical and chemical cues from the surrounding extracellular matrix (ECM). ECM stiffness has emerged as a critical extracellular parameter that can modulate capillary network formation and barrier integrity. Moreover, matrix stiffness can alter how endothelial cells respond to soluble, angiogenic factors released by stromal cells, such as vascular endothelial growth factor (VEGF). In this review, we will discuss how matrix stiffness can affect the formation and structure of angiogenic vessels, and we will highlight the role of this work in the development of therapeutics to treat angiogenesis in cancer. Knowledge of the governing parameters for vessel formation is critical to the intelligent design of materials made to foster blood vessel growth for tissue-engineering applications and pharmaceuticals designed to intervene with newly formed vasculature in diseased tissue.","PeriodicalId":269533,"journal":{"name":"Advances in Regenerative Biology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132555967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
