Abstract
For easily seeding cells in its scaffold, a porous cell scaffold is produced by steps of filling a guiding solution with kinematic viscosity being 50 to 450% of that of a culture medium, in a whole continuous small hole structure having hole diameters of 5 to 3200 μm and an average hole diameter of 50 to 1500 μm, of a sheet-shaped or block-shaped scaffold having a thickness of 2 mm or more, supplying thereafter a culture medium with cells being suspended to an upper side of the scaffold, sucking the guiding solution from a lower side of the scaffold by low suction force, and entering thereby the culture medium with cells being suspended into the whole small hole structure, where a water absorber such as a filter paper is preferably used for sucking the guiding solution by low suction force.
