The design basis and application in urology of the tumor-on-a-chip platform.

Clinical research has been desperately looking for effective treatments for tumors. As the molecular mechanisms of tumors have not been thoroughly defined, and the problem of anti-tumor drug resistance and clinical drug screening are not effective, new ways are currently needed to explore and improve. Given the limitations of traditional cell culture models and preclinical animal models, we review the recently developed tumor chip, a micro-physiological platform based on microfluidic technology that maximizes replication of the human TEM. Here, we focus on the design basis of the tumor microarray and its application in urology oncology, summarizing the challenges facing future development in the field. In conclusion, this review demonstrates the wide range and application of tumor chips and the potential of these systems for the future treatment and management of urological tumors.
