Abstract
Organs-on-chips (OOC) refer to microfluidic devices used to create biomimetic systems of physiological organs. The system contains engineered or natural miniature tissues grown inside microfluidic chips. Organ-on-a-chip technology enables numerous human pathologies to be reproduced, since classical animal models may fail to adequately predict the therapeutic response in humans. This technology can be an intermediate link in the animal-human research system. Moreover, in cancer studies, OOC simulate the three-dimensional hierarchical complexity of tumors in vivo and the tumor microenvironment, being an efficient and cost-effective solution for tumor growth studies and cancer drug screening. Organs-on-chips represent compact and easy-to-use microphysiological functional units simulating physical and biological processes in human body. This extends the possibility of preclinical studies, such as disease modeling or even the development of diagnostic devices. In this regard, the present study is aimed at reviewing the scientific literature in the field of microfluidic devices intended for use in urology and oncourology.
