抜粋

Adult rat hepatocytes formed spherical multicellular aggregates (spheroids) when they were cultured in the pores of polyurethane foam (PUF). The diameter of the spheroids was within the range 100-200 μm. These spheroids partly attached and immobilized in the PUF pores for at least 2 weeks. The albumin production rate by the spheroids increased up to 17.0 μg/106 nuclei per day during the first 6 days and maintained at a high level for 2 weeks. In contrast, the albumin production rate by the monolayer markedly decreased after 3 days. The spheroid culture using PUF seems to be a convenient and simple method for maintaining some differentiated functions of hepatocytes and for making a bioreactor using the function of spheroids.
