A device for culturing a tissue section comprising:

• a frame having a circumferential profile and a central opening defined by the circumferential profile, the frame comprising two frame components, each of which has a circumferential component profile and a respective central component opening defined by the circumferential component profile, which the two frame components being configured to be fitted together flush with one another to form the frame;
• and
• two supporting components wherein the two supporting components are configured to receive a tissue section,
• wherein each frame component of the two frame components comprises a frame component base body and a frame component insert, which are configured to be assembled to form the frame component,
• wherein for each frame component, the frame component insert and the frame component base body are configured to hold the supporting component such that the supporting component is clamped on the frame component spanning the respective central component opening.
