Therapeutic use of differentiated organ cells from human induced pluripotent stem cells (hiPSCs) is one of the promising strategies for regenerative medicine. Differentiation into definitive endoderm is an essential process in the preparation of metabolic organs. However, the manufacturability of differentiation is limited due to the high-cost cytokines required for the differentiation of endodermal lineage. Furthermore, the cytokines remaining in the used culture medium and possible endogenous factors are removed along with toxic metabolites by the medium replacement. To address these problems, the application of dialysis culture can retain and fully utilize their accumulation to create a better culture environment that contributes to differentiation cost reduction.
