Methods of creation of bladder cancer models and their application in preclinical studies (literature review)

Purpose of the study to summarize available data on methods for creating bladder cancer models for their application in preclinical studies. Material and Methods. A systematic literature search was conducted in the Elibrary, Pubmed, GoogleScholar, CyberLeninka databases. Results. The review shows current data on various bladder cancer models and their application in practice. Bladder cancer pathology, identification of diagnostic markers and the development of new therapies are of the main challenges facing the management of bladder cancer. To solve these problems, it is often necessary to conduct preclinical studies using experimental models. Conclusion. Bladder cancer models that can fully reproduce a human disease in terms of histology and behavior are necessary to study the factors involved in cancer development, progression and metastasis. For this, various experimental models are currently used. Human tumor xenografts in mice are widely used. They can reproduce the main pathophysiological features of cancer biology. However, it is necessary to clearly present all the pros and cons of the selected experimental models. The literature review presents modern data on the etiology of bladder cancer, results of preclinical studies on various experimental models, including orthotopic and heterotopic xenografts.
