A microfluidic device includes a base comprising a chamber configured to receive a microfluidic component. A sealing member includes a body, an inlet reservoir, and an outlet reservoir, where the inlet reservoir and the outlet reservoir communicate with the chamber through fluid passages when the sealing member and base are removably coupled. A microfluidic component removably within the chamber includes microfluidic channels on a surface thereof and a tissue culture chamber coupled to at least one of the microfluidic channels. The microfluidic channels and the tissue culture chamber are in fluid communication with the inlet and outlet reservoirs through the fluid passages to form a fluid circuit for directing fluid from the inlet reservoir, through the tissue culture chamber, to the outlet reservoir, and from the outlet reservoir back to the inlet reservoir upon tilting the microfluidic device to a forward tilted position and to a reverse tilted position, respectively.
