Predication on organs-on-chips applications the systematic treatment of breast cancer

Abstract. With the continuous development of cancer therapy, traditional in vitro models have been unable to reproduce the structure of organs and tissues of various parts of the human body, fluid flow and mechanical stimulation characteristics, and the human tumor microenvironment, which is crucial to the study of the behavior and progress of cancer, can not be presented through the animal model in vivo, which shows that the traditional physiological model of cancer can no longer meet the research of human anti-cancer therapy. Benefits from the continuous infusion of cell cultures through the microchannel, the device of organ-on-a-chip improves cell viability and activity and facilitates the simulation of the tumor cell microenvironment, which is expected to further replace traditional zoological experiments. This study reviews a method to simulate the microenvironment of the vitro breast cancer metastasis combined with microfluidic technology, and the application of this device in relevant researches of breast cancer cell metastasis and screening of breast cancer therapeutics.
