Cryopreservation is a method used for preserving living cells by cooling them to very low temperatures. Although cryopreservation methods for oocytes and embryos have been developed for use in reproductive medicine, there are no established methods yet for preserving cell aggregates (spheroids) in regenerative medicine. We have developed a bio-three-dimensional (3D) printer that can fabricate scaffold-free 3D constructs by loading spheroids onto a needle array. We fabricated several constructs such as blood vessels, liver, diaphragm, and
