Mechanism and Role of Tumor Microenvironment in the Initiation and Progression of Bladder Cancer

Abstract

Tumor microenvironment (TME) is a huge network, composed by tumor cells, tumor associated stromal cells, immune cells, cytokines and chemokines secreted by these cells, in which various cells communicate with each other. Bladder cancer is characterized of tendency of relapse, progression, metastasis because of the role of TME. With the application and development of new technologies recently, such as tumor bulk RNA-sequencing and single-cell transcriptome sequencing, the composition of TME for bladder cancer is increasingly clear and the complex cell-to-cell communication network is fully duged, which provides a new vision for the therapy of bladder cancer. This paper reviewed and further analysed the research hotspots of cellular components and extracellular matrix components of bladder cancer on the basis of the latest research progress.
