1. A jig for fabricating a luminal cell structure, comprising:
a plurality of jig members, each of the jig member comprising a plate-shaped support and a comb-shaped member having needle-shaped bodies, wherein the plate-shaped support has an upper surface, a bottom surface, and side surfaces extending in a longitudinal direction, the side surfaces abutting the upper surface in a thickness direction are tapered from the bottom surface to the upper surface,
the comb-shaped member is disposed on the upper surface of the plate-shaped support so that the needle-shaped bodies are aligned in the longitudinal direction of the plate-shaped support and the needle-shaped bodies extends in a thickness direction of the plate-shaped support, and
the plurality of jig members are aligned in a circular arc such that the side surfaces of the plate-shaped support face each other and tips of the needle-shaped bodies point towards a center of the circular arc.
