Apparatuses, systems, and methods are provided for culturing a buoyant target tissue. Embodiments include a first surface configured to culture a first layer of supporting cells, and a second surface configured to culture a second layer of supporting cells. The first layer of supporting cells may be formed on a portion of the first surface and the second layer of supporting cells may be formed on a portion of the second surface. The buoyant target tissue may be added to the first layer of supporting cells. The second layer of supporting cells may be placed on the first layer of supporting cells such that the buoyant target tissue is sandwiched between the first layer of supporting cells and second layer of supporting cells.
