Vascularized microfluidic models of major organ structures and cancerous tissues

Organ-on-a-chip devices are powerful modeling systems that allow researchers to recapitulate the in vivo structures of organs as well as the physiological conditions those tissues are subject to. These devices are useful tools in modeling not only the behavior of a healthy organ but also in modeling disease pathology or the effects of specific drugs. The incorporation of fluidic flow is of great significance in these devices due to the important roles of physiological fluid flows in vivo. Recent developments in the field have led to the production of vascularized organ-on-a-chip devices, which can more accurately reproduce the conditions observed in vivo by recapitulating the vasculature of the organ concerned. This review paper will provide a brief overview of the history of organ-on-a-chip devices, before discussing developments in the production of vascularized organs-on-chips, and the implications these developments hold for the future of the field.
