Microfluidic technology has great potential for complementing and, in some instances, replacing the use of animal models in the testing of medicines and in developing personalised treatments for cancer patients. The maintenance of tissue in an in vivo-like state provides a platform upon which normal and diseased tissue biology can be investigated in a novel way. This review describes the use of microfluidic technology for the maintenance of tissue samples ex vivo and the current state of play for the use of this technology in the replacement of animal models, with a focus on cancer
